Events (some 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 Versão para Computador, Versão para Console, Versão para Celular, Versão para Switch e a versão usada pelo tModLoader, 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, Chuva de Geleias (only if 75/150 slimes are defeated), Exército do Ancião, Frost Legion, Pirate Invasion, Pumpkin Moon, Frost Moon, and Loucura de Marte) and will not appear during events that are time-limited (Blood Moon, Rain, Chuva de Geleias (only if less than 75/150 slimes are killed), Tempestade de Areia, and Solar Eclipse).
Note that certain invasions (Goblin Army, Frost Legion, Pirate Invasion, and Loucura de Marte) have location requirements. The player must be no deeper than 67.5 tiles below the surface, and the player must be within 187.5 tiles horizontally of the location of the invasion. If the invasion has reached the center of the world, then the horizontal check can also be satisfied by the player being within 187.5 tiles horizontally of any town NPC, although at a reduced spawn rate. The town NPC's vertical position is not checked and so they can be housed far above or below your arena.
There are currently 19 / 14 / 8 different events and invasions.

During the event, five ( six during Hardmode) different types of goblins will spawn:

The Old One's Army is a unique Dungeon Defenders 2 crossover event that can be initiated after rescuing the Tavernkeep, who can be found on any layer after defeating the Eater of Worlds/Brain of Cthulhu. The objective is to protect the Eternia Crystal from waves of enemies seeking to destroy it. If the Crystal is destroyed by enemies, the event terminates. If it is kept safe until all waves are cleared, the event is won.
Both the Crystal and its Stand are purchased from the Tavernkeep NPC for coins. Players are inflicted with the Creative Shock debuff for the duration of the event, which prevents the removal or placement of blocks during the entire event within a certain range.
Each wave becomes progressively more difficult. If triggered before any Mechanical Bosses have been defeated, the event consists of 5 waves. If triggered after at least one Mechanical Boss is defeated, the event consists of 7 waves. Once Golem has been defeated, the event becomes even more difficult with the boss Betsy spawning in the final wave. Only one Betsy will spawn during each invasion and defeating it will complete the event. The event also contains 2 mini-bosses, the Ogre and the Dark Mage.
The following enemies are exclusive to the event:
Initiated when around 100 torches accumulate in close proximity anywhere below the Surface layer.
The Torch God is a mini-event that happens when 100 torches accumulate in close proximity underground. The placed torches begin launching small fireballs at the player, extinguishing themselves in the process. The fireballs deal 40 / 80 / 120 damage, and they travel in straight lines through blocks. They can also spawn from torches located off-screen.
While the event is active, the player is inflicted with the Blackout debuff, significantly reducing the player's light vision.
When all torches are extinguished, the event ends. After a brief period, the torches reignite, and if 100 or more torches have been activated, the Torch God's Favor drops near the torches. The player can not challenge the event again once the player has a Torch God's Favor either in their inventory or consumed, and must create another character to do so. A player that has not consumed a Torch God's Favor can continuously challenge and complete the event and obtain more Torch God's Favors, as long as they do not have one in their inventory.

During the event, three different types of unique snowmen will spawn:
All of the snowmen drop Snow Blocks, technically granting the player a way to obtain infinite amounts of Snow.
The event is completed after a certain number of snowmen have been defeated. Afterward, the Santa Claus NPC will spawn during Christmas.
