Notes

• The Magnification Lens also drops from other events with an Eye of Zhaitan - see the item page for a full list of events.
• The Celestial Cartographer's Gear must be assembled before the steps to create the Tyrian Constellation Almanac as the Celestial Cartographer's Gear is used to create the Star Charts.
  • Stars need to be charted during the night — see Day and night for details. Dusk and dawn do not count as night.
  • Star Chart: Cauldron can be done at any time as the Fractals of the Mists are not affected by the day/night cycle.
• The steps to create Cosmic Power can be done at any time.
• The location to use the Celestial Cartographer's Gear at the Hidden Garden is on the second platform (the grassy rock on the way up to the Canticle of Light), above the chest to the east, not near it. You do not need to complete the jumping puzzle to obtain the chart.
• When interacting with the Hero Point to collect item #47 Ley-Line Font Energy, having Quartz Crystals in your inventory appears to prevent the option to acquire the item, offering instead to fuse 25 crystals for a Charged Quartz Crystal. Depositing any quartz crystals to the character's Bank appears to avoid this.
