Collect Celestial Essence from Ascendant rewards
Current 1.3.1-era Resplendent Troves and Dread encounters can provide Celestial Essence for altar use.
Resplendent Treasure Troves in Ascendant Mode campaign zones, or Dread encounters that can occur during Ascendant Mode play.
Repeatable through new troves and Dread encounters, but the material is not guaranteed. Each individual character’s troves are encountered through play; the method has no fixed run yield.
Stop when you have the Essence needed for your planned altar use, or switch to another activity if troves are scarce or Dread threatens the build.
