Scholar Glenna Threats Melded from Torment <Character name>, I've been keeping up with your efforts as you've battled the titans in Janthir. It's not every day that terrors from the Realm of Torment crawl back into Tyria. I'm going to meet you on Mount Balrior—don't think for one moment that I was going to allow you to challenge these beasts without my guidance or witness. This is a critical research opportunity, and one that we would regret not siezing[sic]. Don't kill them before I can get a closer look. —Glenna

Overview

Many important mechanics are hidden unless Character Model Limit is increased.

Several conduits spawn around the arena in different patterns for each phase. Beams will periodically link conduits together. Some mechanics can add one charge to the conduits (up to a maximum charge of three), indicated by an electrified appearance and an AoE around them. The AoE size increases per charge. Players will be punished for each maximally charged conduit during each defiance bar phase. Additionally, each maximally charged conduit that gains charge applies ₁ Exposed (60s) to all players and ₅ Peal of Harmony and ₅ Peal of Discord to Decima.

Each charged conduit releases sparks that must be stopped by a minimum number of players, indicated by the indicator above green circles. The minimum number increases for each charge on the conduit. Decima gains ₁ Charge for each spark that reaches her. Charged conduits can lose charge when discharging sparks, with a singly charged conduit becoming uncharged after releasing 2 sparks.

Decima becomes  Unstoppable upon reaching 10 stacks and defeats all players shortly afterwards. Players should thus minimize the charges on conduits to reduce the damage and mechanical pressure of the encounter.

Decima has  Thrumming Presence and gains ₁ Peal of Harmony and ₅ Peal of Discord every 5% and 10% health lost, respectively.

Phase 1 (100-75%)

Decima starts with ₅ Peal of Harmony uses the following skills during this phase:

Skill	Notes
Chorus of Thunder (Spread)	Targets the closest untargeted players (up to the stacks of  Peal of Discord consumed) with orange AoE's, adding one charge to any conduit hit by them. Targets uncharged conduits (up to the stacks of  Peal of Harmony consumed) near the furthest player, adding one charge to each hit conduit. Both effects are consumed immediately prior to any Orange Arrow attack.
Earthrend	AoE under the boss that downs players, paired with a distant ring-shaped AoE that pushes players towards the boss on-hit. Players may ricochet into conduits and take additional damage.
Fluxlance (Orange Arrow) → Decimation & Harmonic Sensitivity	Targets the furthest player and applies  Galvanic Sensitivity (30s) on-hit, adding one charge to any hit conduits. Players with this effect take increased damage from Green Circles. Players with  Harmonic Sensitivity take increased damage from Orange Arrows. Deals additional damage for each stack of  Charge present on the boss. Alternates with Red Arrow.
Foreshock → Mainshock	Set of large AoE's around the boss.
Fluxlance (Red Arrow)	Targets the furthest player and inflicts lethal damage. Hide behind a conduit to block this attack; however, this adds one charge to all hit conduits. Alternates with Orange Arrow.
Seismic Crash	AoE under the boss that downs players, paired with a shock wave that pushes players away from the boss on-hit. Players may ricochet into conduits and take additional damage.
Sparking Aura (Green Circles) → Galvanic Sensitivity	Sparks originating from charged conduits and applying 1 Charge to the boss upon reaching it. Enough players must stand within the circles (indicated by the overhead icon) to stop and gradually reduce their health. Minimum player count increases with each charge on the conduit (indicated by AoE size around conduit). Players with  Galvanic Sensitivity take increased damage from Green Circles. Damage cannot be mitigated with blocks or invulnerability.
Thrumming Presence	Red-outlined AoE around the boss that pulses low damage and  Harmonic Sensitivity (30s). Players with this effect take increased damage from Orange Arrows. Deals more damage for each  Charge on the boss.

Players that impact a conduit will take damage from the following skills:

Skill	Notes
Fulgent Aura	AoE around charged conduits that grows with each charge.
Fulgent Fence	Lasers between conduits that pushes back players on-hit. Players hit by Earthrend or Seismic Crash will ricochet off of the lasers at high speeds. Cannot be bypassed using evades or invulnerability, however teleports work.

To minimize the charges on the conduits, players must properly handle the Arrow, Spread, and Peal of Harmony mechanics:

1. Red Arrow - Hide behind an uncharged conduit to avoid defeat. Only applicable for the furthest player.
2. Orange Arrow - Position the arrow to not hit any player and conduit. Only applicable for the furthest player.
3. Spread - Avoid letting this attack resolve near a conduit. Only applicable for the closest player(s).
4. Peal of Harmony - Stand in an area with charged conduits to isolate charged conduits in/near the same area. Only applicable for the furthest player.

The Orange Arrow alternates with the Red Arrow: Orange → Red → Orange, etc. Players can reliably bait this attack by being the furthest player right before a player gets targeted. However, standing in the AoE near the boss will also apply  Harmonic Sensitivity, increasing the damage taken by Arrow attacks.

The player targeted by either Arrow attack should also be mindful of  Peal of Harmony stacks on Decima. Each stack summons an AoE that strikes an uncharged conduit near the furthest player (almost always the player targeted by the Arrow attack). The AoE's resulting from this effect should ideally charge uncharged conduits that are behind the group. This minimizes the need for the group to spread far out since the Green Circles will be restricted to a limited section of the arena.

At 75% health, Decima gains  Nova Shield, becomes invulnerable, and unlocks her defiance bar upon finishing her current attack. Breaking this bar applies  Fractured Armor to her, which then applies  Exposed (10s) and  Stun (10s) to her when she becomes vulnerable to damage. Players must prevent all Green Circles from reaching the boss, otherwise they apply  Charge to her and regenerate her defiance bar.

After some time, Decima will use the following skills before becoming vulnerable:

Skill	Notes
Fulminate → Flux Nova	All conduits explode and inflict damage. Conduits with 3 charges additionally inflict 1 Exposed to players, and apply 5 Peal of Discord and 5 Peal of Harmony to the boss. This is followed up by a massive explosion, which deals lethal damage if the boss is fully charged.

After completing her attack, Decima will summon new conduits for the next phase.

Phase 2 (75-40%)

This phase is similar to the previous one aside from a few mechanical changes:

Skill	Notes
Aftershock	AoE's that strike during Fluxlance Fusillade
Fluxlance Fusillade (Orange Arrow)	Replaces Fluxlance but is functionally the same. Now targets the 5 furthest players indicated by a roman numeral (, , , , ). Fires in ascending order. Alternates between 5 Orange Arrows and 1 Red Arrow + 4 Orange Arrows. The Red Arrow targets the most furthest player and is always the first beam. Indicated by a glowing screen border and one of the following effects:  Target Order: 1,  Target Order: 2,  Target Order: 3,  Target Order: 4, or  Target Order: 5.

The Orange Arrow alternates with the Red Arrow: 5 Orange → 1 Red + 4 Orange → 5 Orange, etc. The Red Arrow will always be the first target.

To minimize the damage taken, some players should be designated to be targeted by the Orange Arrows and Red Arrow. The remaining players should then focus on the Green Circles. The Orange Arrows should all ideally be positioned away from those players to avoid applying  Galvanic Sensitivity to them. The Orange Arrows can be staggered to minimize the damage taken while restricting them to a small area of the arena. Additionally, these players must be careful of standing in the red AoE near Decima to avoid taking extra damage from Orange Arrows due to  Harmonic Sensitivity.

The player baiting the Red Arrow should consider being near the side of the players handling Green Circles. This allows both the orange AoE's from consumed stacks of  Peal of Harmony and the Red Arrow to charge uncharged conduits near these players.

Decima periodically channels winds that displace players clockwise, which can be mitigated with  Stability.

At 40% health, Decima regains  Nova Shield, becomes invulnerable, and unlocks her defiance bar. A new set of conduits spawn once she becomes vulnerable.

Phase 3 (40-0%)

This phase is similar to the previous one aside from a few mechanical changes: ^{[verification requested]}

Skill	Notes
Focused Fluxlance (Green Arrow)	Spawns opposite of the most furthest player and targets an outer conduit. Requires 3 players standing within to evenly distribute the damage and block the conduit from getting charged.[verification requested] No additional damage taken even if players have  Harmonic Sensitivity.
Fluxlance Salvo (Orange Arrow)	Replaces Fluxlance Fusillade but is functionally the same. Targets the 5 furthest players but now fires all at once. Alternates between 5 Orange Arrows + 1 Green Arrow and 4 Orange Arrows + 1 Red Arrow. The Red Arrow targets the most furthest player.

The Green Arrow alternates with the Red Arrow: 5 Orange + 1 Green → 4 Orange + 1 Red, etc. The Red Arrow will always be the first target.

3 players need to be in the Green arrow(down from 5) to prevent it from charging the pylon.

Any skills that says "Prevents capture point contribution" will not count the player doing the green arrow or green circles(Like Mesmer distortion).

Either ignore these green arrows because they only give her one stack and instead focus on the more numerable green orbs ^{[verification requested]}, or, have the players who are taking the green orbs (who are not afflicted with  Galvanic Sensitivity) take the Green Arrow.

Decima periodically channels winds that displace distant players clockwise and nearby players counter-clockwise, both of which can be mitigated with  Stability.

Reeg, the Blighter	21,234,960	600	-
Elite Empowering Beast	236,003	240	500

Overview

The fight begins with Greer, the Blightbringer, positioned in the middle, Gree, the Bringer on the left side of the entrance (northwest), and Reeg, the Blighter on the right side of the entrance (southeast). The fight will rotate between three sub-phases: Greer, Breakbar (Elite), and Split (Gree and Reeg).

Greer will target the closest foe, either a player or a player's minion, within a 600–1200 range in front of him. If there is no target within his sight, Greer will use Ripples of Rot to leap to the target area. Players caught in the center of the AoE will be instantly killed, while those in the outer circle will be knocked back and gain  Infectious Rot, which lasts for 20 seconds or until the player is downed. After landing, vine walls will form around him in a ring shape, knocking back any player who touches them. This skill can be prevented by tanking Greer and baiting him to remain in place.

Most of the projectiles can be reflected or blocked. Except, Blob of Blight a large orb that targets up to 3 players, preferring the farthest players which are determined by the blue reticle over their head or the  Target on their effect bar. This orb follows the targeted for 12 seconds, firing multiple smaller projectiles as it moves. If it hits, it will stay in place and fires projectiles for several seconds. If this orb misses the target by dodging through or using an invulnerability, it will lose its targeting and continue moving until it dissipates.

Through the fight, Greer will gain stacks of  Empowered by 2 sources: Orbs from Greer's minions and failing green mechanic. For each stack Greer will deal 5% more damage and at 99 stacks all attacks become unblockable. These stacks can be removed by breaking the defiance bar at 80%, 50%, and 20% of Greer’s health. After that, whether succeed in breaking defiance bar or not. Greer's armor will explode and spawn Elite Empowering Beasts nearby trying to empower Greer. The numbers of these elite will increase depending on phase, from 2 up to 4.

The Eruption of Rot (Green Circles) can be used by Greer, Gree, and Reeg. This skill requires minimum of 2 players within each circle which are determined by the green icon. If a player is within more than one stacking circle, they are instantly downed. If there are not enough players within the circle, a Rot Eruption occurs and the players are given a debuff of  Infectious Rot and the titan gains ₂ Empowered stacks.

At 66% and 33% of Greer health, he will using Invulnerable Barrier, immune to any damage. Which requires players fight with both Gree, and Reeg. Once both of them reach 50% health, Greer will stop using his barrier and become attackable again.

Minions

• Gree, the Bringer and Reeg, the Blighter
  • Gree: a lesser version of Greer, performs melee attacks: Cage of Decay, Ripples of Rot, Sweep the Mold.
  • Reeg: a lesser version of Greer, performs range attacks: Blob of Blight, Scattering Sporeblast.
  • Both of them using Empowering Blast to Greer and they will flee every 25% of their health.

For skills detailed and other shared skills, see below.

• Elite Empowering Beast (Elite)
  • Elite: a titanspawn coming from Greer's bark, spawns after the defiance bar at 80%, 50%, and 20% of Greer’s health. The numbers of elite will increase from 2 to 4 depending on phase.
  • When they spawn, they will try to shoot the empowering orb to Greer. These orbs can be reflected or blocked by player's skills.

Bugs:

• Greer and Gree can aggro on minions and use Ripples of Rot on them.
• At 10% Greer interrupts his skill cast and loses aggro even if a player is in front of him.

She also gains ₁ Rising Pressure every 10 seconds (starting 12 seconds into the fight), with each stack increasing outgoing damage and reducing incoming damage by 5%. These can only be removed upon breaking her defiance bar, which is unlocked every 5% health.

Phase 1 (100-70%)

Two players must interact with the bloodstone shards in the center of the arena to start the encounter. These players will gain red icons above them, the  Deterrence effect, and the   Dispel special action skill. Using this skill drops the bloodstone shard below them and then applies  Bloodstone Saturation. Players with this effect take increased periodic damage when handling a shard. If a Bloodstone shard is not interacted with within 4-5 seconds after being dropped, it will pulse a small red AoE on a 3 second interval which itself is not damaging. But directly correlates to Bloodstone Radiation, the range of which encompasses the whole arena rather than the visual marker on the ground. Bloodstone Radiation deals 10% max. health damage to each player with every pulse and can not be blocked or distorted.

Bugs:

The following transformations do not allow you to pick up the bloodstone shard:

• Ranger:   Celestial Avatar
• Necromancer:   Death Shroud,   Reaper's Shroud,   Harbinger Shroud,   Ritualist's Shroud,   Lich Form
• Engineer:   Elixir S,   Engage Photon Forge
• Thief:   Enter Shadow Shroud
• Elementalist:   Tornado,   Mist Form
• Guardian:   Enter Radiant Forge

The following bundles are unequipped upon picking up the bloodstone shard:

• Ranger:   Summon Cyclone Bow
• Engineer: All Engineering Kits
• Elementalist: All Conjures
• Warrior:   Unsheathe Gunsaber
• Guardian: Tomes

The following effects are removed upon picking up the bloodstone shard:

• Elementalist: bullets from Pistol, projectiles for   Grand Finale

Ura uses the following skills during this phase:

Skill	Notes
Acid Spray	Periodically sprays out white projectiles that inflict  Sulfuric Acid on-hit.
Pressure Blast	Targets two players with an orange AoE (and blurred screen border) that traps hit players in a rising bubble. Players will be downed if not promptly broken out. Players carrying a bloodstone shard can stand within a white circle and use   Dispel to free all players above them.
Propel	Charges towards the furthest player.
Scalding Aura	Periodic damage from standing too close to her.
Sulfuric Acid	Periodic damage from  Sulfuric Acid and applies  Exposed every 5 seconds. Can be cleansed (conversion does not work).
Sulfuric Froth

Toxic geysers spawn 10s after the fight starts and then every 12s throughout the fight removing all and stopping spawns once Ura is below 70% and first uses Create Titanspawn Geyser. Toxic geysers start spawning again every 12s once Ura hits 40%. Above 70%, the furthest player can guide Ura away from these geysers, allowing the group to ignore them altogether.

At 70% health, Ura channels the following skill:

Skill	Notes
Return	A whirlpool around Ura pulls all players towards her. All players are then stacked together and trapped in a rising bubble. Requires a player to use   Dispel. Can be mitigated with invulnerability.

Phase 2 (70%-40%)

This phase is similar to the previous phase, however Ura no longer uses Pressure Blast or Propel, remaining stationary and gains a few new skills:

Skill	Notes
Create Titanspawn Geyser	Channels a large AoE that inflicts  Launch (2.5s) then spawns a Titanspawn Geyser and Elite Fumaroller. If Ura's defiance bar is also up, players can break her to interrupt this skill. A Champion Fumaroller soon spawns if the geyser stays active for too long. The geyser can be instantly defeated upon breaking its defiance bar.
Sulfuric Eruption	Targets a player with an overhead timer and orange circles pulsing out from under them that spawns a Sulfuric Geyser under them after a delay. The spawn of the geyser is followed by a Eruption Vent shockwave. Geysers are protected by a  Hardened Crust, which can only be broken by using   Dispel on top of them.
Eruption Vent	Shockwave generated by the spawn of a sulfuric geyser.
Steam Prison	Targets a player with a ring AoE that spawns a circular wall around them after a delay. The wall reflects projectiles and pushes players back upon contact. Shadowsteps or stability can be used to escape before the wall expires naturally.

Phase 3 (40%-0%)

Ura now resumes using Pressure Blast, and Propel to move, alongside previous skills.

Bugs:

• Breaking her defiance bar at 70% or reaching the HP threshold during a Propel jump can cause her to be self-interrupted and not cast Return.
• At 40% Ura can interrupt her animation and use Propel.
• Breaking her defiance bar below 40% interrupting a skill animation will cause Ura to use Propel as its only available skill.
• A player getting knocked or launched during Pressure Blast will cause the white circle underneath to be desync from the player location, as it's not attached to the player but to the ground.   Dispel must be used at the new player location and not visual effect.
• The Eruption Vent shockwave visual of Sulfuric Geysers is desync from its hitbox. The further away the geyser spawn is from the player, the bigger the desync becomes.
• Supposedly (needs verification), if the camera is not pointing at the spawn point position of the Eruption Vent, the visual will look even further accelerated and desync.
•   Dispel can remove the debuff off a geyser but not kill it due to the two actions of the skill seemingly having different radiuses of affect.
• The Eruption Vent shockwave of a Sulfuric Geyser can spawn tilted when the Geyser is placed on uneven terrain and can be spawned underneath the map if the geyser is placed underneath (such as in a puddle).
• Blinking through the "edge" of the arena will cause Acid Rain to not be applied to the player.
• The Fumaroller spawning from the south west Titanspawn Geyser often runs off to the west with no target even if nothing is in that direction to aggro it.
• Spawning a Sulfuric Geyser on raised terrain or while jumping can cause the player to get stuck in its hitbox.
• The No Geysers, No Problems achievement can be obtained in normal mode under certain conditions.

As of 2025-06-04:

• Titanspawn Geysers will not stop spawning NPCs even when their defiance bar has been broken.

Challenge and legendary mode

Overview

General

• Ura, the Steamshrieker is now named Godscream Ura

Monster buffs

• Increased boss health but reduced defiance bar strength
• Ura regains 15% health upon reaching 1% health
  • LM: Now regains 30% health and spawns Legendary Ventshots from Titanspawn Geysers

<Character name>: Wow. Pretty.

<Character name>: Wasn't expecting a hike...

Crossing the Eldren Bridge, one of the following

<Character name>: Moving out.

<Character name>: Going to scout ahead.

Reaching Balrior Ravine

Scholar Glenna: Help! Anyone!

<Character name>: Is that...

Scholar Glenna: Whoa! The heck you doing? I'll bite back!

<Character name>: I'm coming!

After cleansing the camp of titanspawn

Scholar Glenna: Excellent timing, Commander!

<Character name>: I see little has changed...

Scholar Glenna: Heh, whoops. Sorry, I was gonna wait at the base of the mountain for you. But what can I say? The call of research...

<Character name>: Glad we made it before things escalated.

Scholar Glenna: Ha, you and me both! Now, you've got a couple titans to kill. I'm here to observe.

Scholar Glenna: Just be careful if you're headed out. Haven't been able to scout much farther myself. Titanspawn everywhere.

Scholar Glenna: Heavy concentrations of them to the east and west. Might want to pick a direction and start there.

Scholar Glenna: Oh, and it's good to see you again. Been far too long. Now don't get yourself killed!

Engaging Decima

Decima, the Stormsinger: (whimpers)

Decima, the Stormsinger: N-no! No...no...

<Character name>: Need cover.

<Character name>: Steady! Everyone!

Decima, the Stormsinger: The sound of your flesh, crackling and burning away...

Decima, the Stormsinger: Ha! I rumble! And rumble! And rumble!

Decima, the Stormsinger: Banal little bug.

Decima, the Stormsinger: Persistent little pests!

Decima, the Stormsinger: Still alive? I'll just have to scrub a little harder.

Decima, the Stormsinger: Ah... I feed!

Decima, the Stormsinger: Does this ignite a memory?

Decima, the Stormsinger: Vile vermin.

Engaging Greer

Greer, the Blightbringer: Away from me.

Greer, the Blightbringer: Blind is the eye that looks past the predator.

Greer, the Blightbringer: Erroneous, your spirit...

Greer, the Blightbringer: Foredoomed you have always been.

Greer, the Blightbringer: (growls)

Greer, the Blightbringer: A putrid storm builds...

Greer, the Blightbringer: (groans)

Greer, the Blightbringer: I cannot be defeated.

Engaging Ura

Ura: I told you to flee. But that offer has passed.

Ura: Boil over.

Ura: Do you see the delicate line between hope and viridity?

Ura: I will boil your oceans! All will disintegrate!

Version history

Patch	Changes
June 24, 2025	(Undocumented) Improved Ura's frontal aggro making it easier to "tank". (Undocumented) Fixed Titanspawn Fumaroller spawn rate. Fumarollers no longer spawn on a 10 seconds interval but the original 15 seconds. (Undocumented) Ura heals to 31% instead of 41% while Legendary Challenge Mode is active. (Undocumented) Ventshots present in the encounter are now capped at 4 from 7 previously.
June 04, 2025	Fixed an issue that caused fumarollers to spawn at the incorrect difficulty level in the Mount Balrior raid.
June 03, 2025	Fixed an issue in normal and challenge mode that caused the final attack of Decima's Mainshock skill to hit twice. (Undocumented) Titanspawn Geysers now spawn a single Elite Fumaroller and no other monsters across all difficulties in Mount Balrior.
April 15, 2025	Added additional time to the event timer when Godscream Ura's armor is shattered at 1% health during Ura's legendary challenge mode encounter in Raid: Mount Balrior. (Undocumented) The time increase at 1% affected Ura's challenge mode too. The time gained is 1 minute.
April 03, 2025	The Acid Rain effect applied to players who leave Godscream Ura's combat arena in Raid: Mount Balrior while the encounter is ongoing will no longer be removed when players are downed.
April 01, 2025	Godspoil Greer will now properly reset if players fail the Raid: Mount Balrior challenge mode encounter while he is in his shielded state.
March 25, 2025	Update 2: Fixed an issue that caused some legendary mode mechanics to persist if the difficulty was reduced after attempting the Ura legendary mode encounter in Raid: Mount Balrior. Fixed an issue that could sometimes cause Ura's Eruption Vent shock-wave effects to play at the wrong angle in Raid: Mount Balrior. A legendary mode encounter with Ura is now available. Decima's challenge mote will no longer appear until the legendary sentient conduit is defeated. Respawn locations are now correctly updated when engaging and defeating Decima with the challenge mote active. Fixed an issue that sometimes allowed a standard or deadly beam attack to pierce a conduit and hit players taking shelter behind it in Decima's challenge mode. Updated Decima's movement behavior during the first and second phases of her challenge mode to reduce cases where she fails to move to a new position. Fixed an issue that caused one of Decima's beam attacks in the second phase of her challenge mode to fire in the wrong direction. Fixed an issue in Decima's normal and challenge mode encounters that prevented Fluxlance Fusillade target indicators from properly disappearing. The skill will now fire a beam attack and the target indicator will disappear, even if the targeted character is dead. Fixed an issue in Decima's normal and challenge mode encounters that could cause dancing sparks to begin moving again even when enough players were within range of a spark's damage aura. (Undocumented) Decima's health during the challenge mode has been adjusted from 97,020,176 to 116,424,224. This has later been reverted back to 97,020,176 health. (Undocumented) The indicator for Steam Prison on players no longer scales with their model size, which was making it appear larger/smaller than the ring will actually be depending on their race. It now has a fixed size.
March 12, 2025	Fixed an issue which could cause the pulsing damage inflicted when dropping a bloodstone shard in the challenge mode Ura encounter in Raid: Mount Balrior to persist after the shard is picked up.
March 11, 2025	Three challenge motes have been added, allowing players to activate challenge mode versions of the Greer, Decima, and Ura boss encounters. Fixed an issue that could cause players to sometimes be teleported into Decima's arena while the encounter was resetting. The visual effects for Decima's Fulgent Fence skill have been updated to reduce visual noise. Entry to the Mount Balrior raid is now consistent with previous raid instances. If the first player to enter the instance has defeated the final boss since the most recent weekly reset, a fresh instance will open instead of a cleared instance. (Undocumented) A 10 minute enrage timer and the corresponding The World Ends in Decay skill have added for the normal mode Greer boss encounter. (Undocumented) The health for the Legendary Sentient Conduit has been reduced. (Undocumented) Blob of Blight now despawn upon being blocked or evaded. (Undocumented) Greer's pre-event no longer spawns 2 additional Elite Empowering Beasts when a new player enters the raid after they mobs were initially killed. (Undocumented) Ura's Create Titanspawn Geyser will spawn the geyser even if her defiance bar is broken and the attack is interrupted. (Undocumented) When a player is targetted to spawn a Sulfuric Geyser, they now automatically receive Superspeed.
December 10, 2024	Decima: Focused Fluxlance now requires only three players in the beam instead of five. Because base damage is divided among players, the base damage was also reduced to keep final damage numbers consistent. Fixed an issue that caused players to be miscounted by Focused Fluxlance. The mechanic will now fail consistently if too few players stand inside the beam. Decima's defiance has increased by 25%. However, the channeling for Flux Nova is now shortened when Decima's defiance is broken and she gains  Fractured Armor.  Peal of Harmony is now gained for every 5% of damage taken instead of every 3% of damage taken. This will reduce the number of dancing sparks generated overall. Fixed an issue that caused the telegraphs for Decima's various fluxlance attacks to be invisible to some players. When Decima is defeated, any telegraphed fluxlance attacks will be interrupted and vanish immediately. To provide players with additional time to position themselves for Focused Fluxlance, all fluxlance attacks in the encounter's third phase now have an extra half second of warm-up time before they fire. Players standing directly under Decima during Earthrend and Seismic Crash will now enter the downed state and be knocked away. Fixed an issue that prevented fluxlance attacks in the encounter's first phase from targeting downed characters. Greer: Greer no longer has permanent  Resolution. Enfeebling Miasma's attack region now matches its warning areas, and lingering gas clouds have area warning circles. Greer's projectiles can no longer be reflected back at him. Those projectiles will instead be destroyed, keeping the protective utility of the affected skills. Surviving Empowering Beasts will now be removed when Greer is slain. Blob of Blight now correctly stays in place after it hits a targeted player, and smaller projectiles are now properly destroyed on impact. Greer's first two stomp attacks in his Stomp the Mould skill are now blockable and dodgeable. Greer should now attack pets less often. Ura: Fixed an issue that could cause the  Sulfuric Acid effect to persist after defeating the boss. Added additional telegraphing for players targeted by Ura's Eruption Vent ability. General: Fixed an issue that caused unintended scaling for events that require the defeat of a legendary titanspawn. Fixed an issue that could cause events that require the defeat of a legendary titanspawn to stall. Fixed an issue that allowed players to leave Greer and Decima's arenas midfight. Fixed an issue that prevented some profession and elite specialization cooldowns and resources refreshed and reset at the start of an encounter if the player was mounted at the time. (Undocumented) Decima's health has been adjusted from 70,795,000 to 60,165,720.
November 22, 2024	Moved Greer's respawn trigger area in the raid instance to work properly with the player respawn spot. Changed part of the logic around the Greer event to prevent exploits.
November 19, 2024	Update 2: The bloodstone shards to begin the Ura fight no longer spawn in the Mount Balrior raid if the instance creator has previously defeated the boss for the week. Fixed a bug in which bloodstone shards would not pulse damage when left on the ground after using the Dispel skill in the Ura encounter in the Mount Balrior raid. Added more map markers in the Mount Balrior raid. (Undocumented) Decima's health has been adjusted from 83,288,232 to 70,795,000. Mount Balrior has been added to the game.
