Lunar Events


 * "Celestial creatures are invading!"

The Lunar Events are a series of four late-Hardmode events initiated by defeating the Lunatic Cultist boss. Once the boss is defeated, four different sections of the world each show a large moon in their backgrounds and spawn several unique enemies at high spawn rates, with one corresponding Celestial Tower in each. These areas can be found on the minimap via icons that represent each of their Celestial Towers.

Defeating a Celestial Tower reverts an area back to normal. In order to damage a Tower, one must first kill 100 enemies (150 in Expert mode) from within its section, which removes the shield that protects the Tower and makes it vulnerable to attacks.

Defeating all four Celestial Towers triggers the status message "Impending doom approaches...", signifying that Moon Lord, Terraria's final boss, is about to spawn. It spawns one minute after the message appears.

Tips

 * It can be helpful to launch the Lunar Events even if you don't have the means to survive them fully yet, as you will gradually defeat pillars, then can use the drops from that pillar to defeat the next one, and so on. Even if you lose to the Moon Lord, you will be much more prepared than you were before.
 * Once the final pillar has been destroyed and "Impending doom approaches...", do not save and exit the game, as doing so will abort the event and stop the Moon Lord from spawning.
 * A Solar Eclipse can occur during the Lunar Events. However, while near a pillar, the pillar's enemy spawns will override those of the Solar Eclipse.
 * The pillars retain their damage, regardless of player deaths.
 * An effective setup for melee players is The Horseman's Blade and Turtle Armor. Then build a small area where you can have lots of statues that spawn enemies so when your sword kills them, it spawns homing pumpkin heads. Have up to three statues of the same type.
 * Because neither sentries nor the pillars despawn or leave when the player dies or leaves, as monsters do, sentries can continue attacking a pillar with no players nearby, as long as the shield is already gone.

Trivia

 * The music played during the Lunar Events was made available as part of the second Terraria Soundtrack volume under the title "Lunar Boss" despite not being implemented in the game.
 * This is one of the only two events in the game whose enemies don't drop coins, along with the Old One's Army.
 * The game's files identify this event as the Lunar Apocalypse.
 * While the Lunar Events are active, events such as the Pirate Invasion may occur.
