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 Desktop only.png Desktop version, 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 (such as the Goblin Invasion and the Frost Moon), and will not appear during events that are supposed to last a certain amount of time (including the Blood Moon 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.

There are currently 14 (Desktop only.png) / 7 (Console only.png) / 7 (Mobile only.png) different events and invasions.

Pre-Hardmode[edit | edit source]

Blood Moon[edit | edit source]

Blood Moon2.png

The Blood Moon is an event that has a 1 in 9 (11.11%) chance of happening every night as long as one player in the world has 120 health or more. A message saying: "The Blood Moon is rising..." is displayed when the event starts. During this event, the spawn rate of enemies and the maximum amount of enemies that can be on the screen at any time is increased. Enemies will also spawn near NPCs, even when they normally do not. It can be skipped using an Enchanted Sundial.

During a Blood Moon, Zombies and Werewolves can open doors after a few hits.

Special enemies spawn in addition to the usual enemies of the surface biome the players stands in. The following enemies spawn during a Blood Moon:

* Blood Zombie.png Blood Zombies (Desktop only.png): A stronger variety of a zombie. Increases in movement speed the closer they are to a player.
* Drippler.png Dripplers (Desktop only.png): Commonly found flying enemies.

Deathweed.png Deathweed will also bloom during a Blood Moon. They can be found in the Corruption/Crimson even if it isn't a Blood Moon.

All water in the world aside from the ocean, Fish Bowls, and Water Fountains gain a blood red color, including Rain. It does this similarly to the Crimson Biome.

Extra 9.pngGoblin ArmyExtra 9.png[edit | edit source]

The Goblin Army is an event that has a 1 in 3 chance of occurring every dawn if certain criteria are met. It can also be summoned using a Goblin Battle Standard. Before the event starts the message: "A Goblin Army is approaching from the [east/west]!" will be displayed a certain number of times. When the Goblin Army is about to spawn around the player's spawn point, the message: "A Goblin Army has arrived!" will be displayed.

During the event, five (Desktop only.png six during Hardmode) different types of Goblins will spawn:

* Goblin Peon.png Goblin Peon: A basic Goblin that can destroy doors and inflicts basic melee damage.
* Goblin Sorcerer.png Goblin Sorcerer: A Caster-type enemy that fires Chaos Balls which can travel through walls. It teleports to a location near the player after firing 3 projectiles.

* Goblin Warrior.png Goblin Warrior: A Goblin with more health, defense, and damage than others, that takes the most time to kill. It cannot collide with wood platforms in any way.

If the world is in Hardmode:

* Goblin Summoner.png Goblin Summoner (Desktop only.png): A Goblin mini-boss that appears during Hardmode, will summon multiple Shadowflame Apparitions to attack the player.

Although they do not appear in the Goblin Invasion, Goblin Scouts can be found rarely on the outer thirds of the map. They drop Tattered Cloth which is used to make the summoning item for this event.

The "Boss 1" theme used to play during a Goblin Army , but as of the 1.3.0.1 update, the Goblin Army has its own theme. This theme is also present on the 3DS version.

After the 1.3 update, a progress bar shows the percentage of completion of the event

When a certain number of enemies are defeated, the message: "The Goblin Army has been defeated!" will display.

After defeating the event for the first time, the Goblin Tinkerer will be able to spawn underground.

Rain[edit | edit source]

The most common event is Rain. Rain can occur in any surface biome, changing the theme music, the background, and lighting dims, Goldfish walk on land, and some new enemies spawn, such as Flying Fish or Umbrella slimes, and Zombies may occasionally wear rain gear. Once the rain has completed the effect fades away and the affected biome returns to normal. Rain in the snow biome becomes a blizzard.

Slime Rain[edit | edit source]

Desktop only.png Desktop-Only Content: This information (or parts of it) applies only to the desktop version of Terraria.

The Slime Rain is an event that has a random chance of occurring in a world, and the event starts when the message "Slime is falling from the sky!" is announced in chat. It can only appear, though, if the player has at least 140 health and 8 defense (except in Expert Mode, where it can occur with a significantly decreased chance before meeting the criteria), in which after those criteria are met the random chance of occurring will be put into play. During this time, different variations of slimes fall from the sky constantly until the day or night is over. If the player kills 150 (75 if King Slime was previously defeated) slimes before the event naturally ends, King Slime will spawn. Once the event is over, the message "Slime has stopped falling from the sky." will be displayed in chat.

Many types of slimes spawn including:

* Blue Slime.png Blue Slime: A common slime.
* Green Slime.png Green Slime: A common slime.
* Purple Slime.png Purple Slime: A common slime.
* Pinky.png Pinky: A rare slime who will always drop Pink Gel (Desktop only.png).
* King Slime.png King Slime: The boss of all slimes, spawns at the end of the event if enough slimes are killed.


Party[edit | edit source]

Desktop only.png Desktop-Only Content: This information (or parts of it) applies only to the desktop version of Terraria.

The Party is an event that takes place when a Party Center is active. When it occurs, all NPCs will wear a Party Hat (except the Tax Collector and Old Man). When the event ends, the message "Party time is over!" is announced in chat. The event will end at night (7:30 PM) in the game. A party has a random chance to occur at any dawn, without needing a Party Center near the involved NPCs. When NPCs initiate their own parties, any placed Party Center will activate, and a pink status message will display "Looks like [NPC name] & [NPC name] are throwing a party!" Sometimes only one NPC will throw a party and even three NPCs can throw a party. The pink status message will adapt to however NPCs are throwing the party.

Sandstorm[edit | edit source]

Desktop only.png Desktop-Only Content: This information (or parts of it) applies only to the desktop version of Terraria.
SandstormBiomeBanner.png

Sandstorms occur randomly while the player is in a Desert and do not affect other biomes while active. During a sandstorm, the Mighty Wind debuff will be inflicted, pushing creatures afflicted with it in the direction of the wind, and particles will appear in the dusty yellow background. Sandstorms can also occur in Corrupted, Hallowed, or Crimson deserts.

In addition to regular Desert enemies, the following enemies will spawn:

* Angry Tumbler.png Angry Tumbler

Desktop only.png Desktop-Only Content: This information (or parts of it) applies only to the desktop version of Terraria.
BiomeBannerOldOne'sArmy.png

The Old One's Army is a unique Dungeon Defenders 2 crossover event that can be triggered by placing the Eternia Crystal on the Eternia Crystal Stand. The objective is to protect the Eternia Crystal from waves of enemies seeking to destroy it. If the Crystal is destroyed, the event terminates. If it is kept "alive" until all waves are cleared, the event is defeated.

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.

Each wave becomes progressively more difficult. When 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:

* Ogre.png Ogre
* Dark Mage.png Dark Mage
* Betsy.png Betsy
* Old One's Skeleton.png Old One's Skeleton
* Etherian Wyvern.png Etherian Wyvern
* Etherian Javelin Thrower.png Etherian Javelin Thrower

Hardmode[edit | edit source]

Extra 7.png Frost Legion Extra 7.png[edit | edit source]

Frost Legion.png

The Frost Legion is an event that functions similarly to the Goblin Army, but it requires an item to start the event, which is only attainable in Hardmode. The seasonal update allows enemies to drop Presents. If in a Hardmode world these presents have a 1 in 13 chance of containing a Snow Globe, which is used to spawn the Frost Legion. Before the event starts, the message: "The Frost Legion is approaching from the [east/west]!" will display. When the Frost Legion is about to spawn around the players spawn point, the message: "The Frost Legion has arrived!" will be displayed.

During the event, three different types of unique snowmen will spawn:

* Mister Stabby.png Mister Stabby: A Snowman enemy that wields a knife, inflicting melee damage.
* Snowman Gangsta.png Snowman Gangsta: A Snowman that inflicts ranged damage with a gun.
* Snow Balla.png Snow Balla: A Snowman that throws snowball projectiles, which form Snow Blocks on impact.

All of the snowmen drop Snow blocks, technically granting the player a way to obtain infinite amounts of Snow.

When the Frost Legion have arrived, the "Boss 3" theme will play.

When the last wave of snowmen has spawned, the message: "The Frost Legion has been defeated!" will display.

After the Frost Legion has been defeated, the Santa Claus NPC will be available (Only in the Christmas period) and will move into an empty home.

Solar Eclipse[edit | edit source]

type=gif

The Solar Eclipse is a rare Hardmode event that has a 1/20 chance to occur each day, as long as any Mechanical Boss has been defeated. It can also be summoned with a Solar Tablet Desktop only.png. A Solar Eclipse will be announced at dawn with the message "A Solar Eclipse is happening!". The sun will rise, obscured by the moon, dramatically reducing natural light to a level darker than night time. Normal biome enemy spawns are replaced with special enemies that can spawn near NPCs, and spawn much more frequently and in greater numbers than usual. It can be skipped using an Enchanted Sundial.

The enemies that spawn during a Solar Eclipse at the start of Hardmode are as follows:

* Swamp Thing.png Swamp Thing: A swampy creature that can run quickly. Can also drop a Broken Hero Sword (Console only.png Mobile only.png).

Extra 11.png Pirate Invasion Extra 11.png[edit | edit source]

Pirate Invasion.png

The Pirate Invasion is an event that is very similar to the Goblin Army. It can spawn randomly, or be summoned by the use of a Pirate Map, which can be obtained from killing any mob in the Ocean biome during Hardmode. When activated, a message will warn all players that "Pirates are approaching from the East/West!" When the Pirate Invasion has reached the original spawn point, a message will send, saying "The Pirates have arrived!"

During the event, six different enemies themed around a pirate crew will spawn:

* Pirate Deckhand.png Pirate Deckhand: A simple enemy. Very similar to the Goblin Peon.
* Pirate Deadeye.png Pirate Deadeye: A pirate enemy who carries and shoots a gun.
* Pirate Corsair.png Pirate Corsair: Similar to the deckhand, but a little faster with a little more damage. He carries the Cutlass.

* Pirate Captain.png Pirate Captain: The strongest pirate enemy you will encounter. He walks normally until the player enters his range, and then enters attack mode where he mounts a machine gun and starts to rapid fire at the player. Upon being attacked, he will cease to fire, and will not start firing again until the player stops attacking him. He can also fire cannonballs.
* Parrot.png Parrot: A flying enemy that seems to spawn near the Captain.
* Flying Dutchman.png Flying Dutchman(Desktop only.png): A flying pirate ship mini-boss that appears only after the event reaches 50%. It has four cannons with individual health bars that shoot multiple grenades at the player's location. All 4 cannons must be destroyed to defeat the ship. It also spawns many of the normal Pirate Invasion enemies.

Before the 1.3.0.1 update, the music played during the event was the Golem theme. On the Desktop and 3DS versions, the Pirate Invasion now has its own track.

Upon defeating the Pirate Invasion, a message will appear stating that "The Pirates have been defeated!".

Defeating the Pirate Invasion unlocks the Pirate NPC, which will arrive during daytime if the world has a suitable housing.

Extra 12.png Pumpkin Moon Extra 12.png[edit | edit source]

Pumpkin Moon.png

The Pumpkin Moon is a Autumn/Halloween-themed event that can only be summoned at night with the Pumpkin Moon Medallion. Unlike most other events, the Pumpkin Moon takes place in distinct waves, each one preceded with the message "Wave [#]: [list of the monsters that will be spawning in the wave]". There is a total of 15 waves, which grow harder as the night wears on, culminating in the "Final Wave," which lasts for the remainder of the night. Later waves will contain multiple boss enemies, so it is not recommended for players to summon the Pumpkin Moon until they have end-game weapons and armor and well-reforged accessories. It can be skipped using an Enchanted Sundial, however, it would be considered a waste of resources.

The Pumpkin Moon has seven monsters, in increasing order of difficulty:

* Scarecrow.png Scarecrow: The most basic monster, it slowly walks or hops about.
* Splinterling.png Splinterling: A slow but resilient monster that is highly resistant to knockback.

The Pumpkin Moon used the "Eclipse" music track but got its own in 1.2.1.2. Though there are no rewards for surviving the event, most (if not all) of the enemies can drop unique items, including Spooky Wood and equipment like the Spooky Hook and Raven Staff.

Extra 8.png Frost Moon Extra 8.png[edit | edit source]

Frost Moon.png

The Frost Moon is a Christmas-themed event similar to the Pumpkin Moon that can only be summoned at night with the Naughty Present. It uses the same wave system as the Pumpkin Moon, with each new wave starting with the message "Wave [#]: [list of the monsters that will be spawning in the wave]". The Frost Moon also has an additional five "bonus waves" after the "Final Wave", making the max wave count to 20. Enemies have similar behavior to Pumpkin Moon counterparts, but are tougher, making this event the hardest as of Terraria 1.2.4.1. It can be skipped using an Enchanted Sundial, however, it would be considered a waste of resources.

It has 11 types of enemies:

* Gingerbread Man.png Gingerbread Man: Basic enemy found in the early waves.

The Martian Madness event is a post-Golem event. It is unique from the others in that in order to start it you must find a Martian Probe randomly around the surface and space levels of the world and go into its light. Once you're discovered by a Martian Probe, it will float away and, if not destroyed by the time it leaves the screen, it will initiate the Martian Madness event, displaying the message "Martians are invading!". If you do not wish to unintentionally begin the event, it is recommended to destroy the Probe immediately. The Martian Madness event has enemies as follows:
