"The frigid moon shimmers brightly."
Endothermic Energy is a post-Moon Lord crafting material dropped by most Frost Moon enemies after The Devourer of Gods has been defeated. It is used to craft several late-game items typically themed around cold temperatures, and it is also used in conjunction with Darksun Fragments, Nightmare Fuel, and Polterplasm to make Ascendant Spirit Essence.
- The item is a reference to the Endothermic Fire from Don't Starve, which cools the player.
