Lunar Mode Walkthrough
Once the moon lord dies, the world will enter Lunar Mode, and a Lunar Pillar will spawn above the Dungeon. When destroyed, it will drop a Lunar Forge . Right-click this with a Lunar Sigil and Kheatr will spawn, a boss slightly harder than the moon lord based on stats but you can only attack it's head (like the crawltipede) and will drop lunar essence. This can be used as a farming technique for lunar essence. Lunar Mode is a peaceful mode, until you break the pillar. Doing this will unleash many enemies (such as the Yoyo Slime, etc).
