Events



Events (also known as Invasions) are temporary occasions where varieties of special enemies spawn, most at elevated spawn rates, even near NPCs, and attack players. Some events can occur randomly during gameplay, while others can be triggered via certain summoning items or special circumstances. Events spawn their own unique enemies not seen during ordinary gameplay, which can, in turn, drop unique items that are only obtainable within the event. Some events also bring unique visuals and a unique atmosphere, such as an altered Moon and noticeable shaders applied to the screen. Events also are accompanied by their own special music, adding on to their theme. Depending on the particular event, they may last until a certain time limit is reached, or until a certain number of enemies are defeated.

On the, a progress bar can be seen in the bottom right corner of the screen to indicate how far the player has gone into the event, and how far they are from completing it. It only appears during invasion-style events (Goblin Army, (only if 75/150 slimes are defeated),, Frost Legion, Pirate Invasion, Pumpkin Moon, Frost Moon, , and ) and will not appear during events that are supposed to last a certain amount of time (Blood Moon, Rain,  (only if less than 75/150 slimes are killed), Sandstorm, and Solar Eclipse).

Note that invasions seem to require that at least one NPC is nearby; if an invasion's progress bar disappears beyond a certain distance, it may be necessary to place a house near the area. The game only checks horizontal distance to the NPC; you can house them far above or below your arena.

There are currently 14 / 11  / 8  different events and invasions.

All of the events of Terraria except the Party event on the, created to celebrate Terraria's 5th birthday, spawns unique enemies.
