Lunar Events

The Lunar Events are a series of Hardmode, post-Plantera events initiated by defeating the Lunatic Cultist boss. Once the boss is defeated, several surface biomes show a large moon in their backgrounds, and spawn several unique enemies. The moon biomes will spawn in four distinctly spaced sections of the world. Defeating the pillar will revert the area back to normal. In order to defeat any of the four pillars, one must first kill many monsters corresponding to the selected pillar in order to remove the barrier that is protecting it.

Each of the four variants has a different theme, along with a corresponding Celestial Tower variant that acts as the centerpiece of the event.

The variations are as follows: Upon defeating all 4 pillars, the message "An impending doom approaches" appears in chat, in which shortly after, the Moon Lord will spawn on top of the player. (check chat message)

Tips
It is advised to first destroy the Nebula Pillar, as it grants access to the Nebula Blaze, an extremely fast and powerful homing magic weapon that will help take down the other three pillars. The Nebula Pillar can be easily taken down with a Razorpine and healing Spectre armor.. Or to beat the Vortex Pillar and get the very powerful Vortex Beater, which with shroomite armor, can easily take care of the other three pillars.
