Events



Events are temporary occasions when enemies spawn at elevated spawn rates, even near NPCs, and attack players. Some Events occur randomly, while others can be triggered via 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, such as an altered Moon. Depending on the particular Event, they may last until a time limit is reached, or until a certain number of enemies are defeated.

There are currently 10 different Events.

Blood Moon


The Blood Moon is an event that has a 1 in 10 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.

During a Blood Moon, Zombies, Werewolves and Possessed Armor 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 only during a bloodmoon: If the world is in In Hardmode
 * s are a faster, stronger variety of a zombie.
 * s are flying melee enemies.
 * is an uncommon zombie.
 * is an uncommon zombie.
 * spawns in place of the standard bunny, and is not anymore a harmless critter.
 * spawns in place of Goldfish in bodies of water, or even can be seen walking if simultaneous rain. It will now attack Players.
 * spawns in place of Penguin in the Snow Biome. Again, it is now an enemy. The only difference is, instead of turning purple, it becomes bloody.
 * , a potentially very dangerous enemy, because it sends bombs flying toward the player.

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 and near a Water Fountain gains a blood red color, including Rain. It does this similarly to the Crimson Biome.

[[File:Extra 9.png]]Goblin Army[[File:Extra 9.png]]


The Goblin Army is an event that has a 1 in 15 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 players spawn point the message: "A Goblin Army has arrived!" will be displayed.

During the event five (six during hardmode) different types of unique Goblin will spawn:


 * : A basic Goblin that can destroy doors and does basic melee damage.


 * : A Caster-type enemy that fires a projectile which can travel through walls. It can teleport.
 * : A quicker Goblin that can also jump higher than the others.
 * : 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.
 * : A Goblin that shoots arrows at the player.
 * (1.3) A Goblin that is introduced during hardmode, will summon multiple Shadowflame Apparitions to attack the player.
 * Altough they do not appear in the goblin invasion, Goblin scouts can be found rarely on the outer thirds of the map.

The "Boss 1" theme used to play during a Goblim Army invasion, but as of 1.3, the Goblin army has its own theme.

When the last wave of Goblins has spawned, the message: "The Goblin Army has been defeated!" will display, and the Goblin Tinkerer will spawn underground (only if defeated for the first time).

Any Goblin will drop banners and a 100% chance of dropping Spiky Balls.

Slime Rain
Added in the 1.3.0.1 update, a new event was released where in context it says "Slime is falling from the sky!". During this time, many different slimes fall from the sky constantly until the day or night is over. Towards the end of the event a King Slime may spawn. Once done, in context it will say "Slime has stopped falling from the sky." The event lasts for one in-game day or night.

Many types of slimes spawn including:


 * : A common slime. Can drop Blue Slime Banner.
 * : A common slime. Can drop Green Slime Banner.
 * : A common slime. Can drop Purple Slime Banner.
 * : A common slime. Can drop Sand Slime Banner.

[[File:Extra 7.png]]Frost Legion[[File:Extra 7.png]]


The Frost Legion is an event which is very massive, similarly to the Goblin Army, but the item to start the event is only attainable legitimately in Hardmode. The seasonal update allows mobs to drop Presents, if on a Hardmode world these presents have a 1 in 13 chance of containing a Snow Globe, the item 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:


 * : A Snowman wielding a knife.
 * : A Snowman that inflicts ranged damage with a gun.
 * : A Snowman that throws snowball projectiles, which form Snow blocks on impact.

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 and will move into an empty home.

Solar Eclipse


The Solar Eclipse is a rare event that was included with the 1.2 update. A Solar Eclipse is a Hardmode event that can occur with approximately 1/25 chance after a Mechanical Boss has been defeated. 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 closer to nighttime. 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. The Solar Eclipse can also be summoned with a Solar Tablet.

The enemies that spawn are as follows:
 * : A swampy creature that can run quickly. Can also drop a Broken Hero Sword (very rare).
 * : A zombie-like creature that has much more health than a normal zombie. Can also drop a Broken Hero Sword (very rare).
 * : A slow-moving zombie variant with high health. It is capable of firing a laser.
 * : A dark creature that is similar to the wraith. Reapers are best dealt with by standing on a platform over an empty space.
 * : Enemies that spawn as very fast bats that may target the player. They morph into their humanoid form upon coming close to a player. Can drop Broken Bat Wings.
 * : A flying enemy that has much more health than any other in the Solar Eclipse. They can fly through blocks and will continually attack the player until killed. It drops a Broken Hero Sword and The Eye of Cthulhu yoyo.

The solar eclipse lasts for one (1) in-game day.

[[File:Extra 11.png]]Pirate Invasion[[File:Extra 11.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 (Except in the Mobile Version where it can be dropped anywhere prior to the Ocean biome). When activated, a message will warn all players that "Pirates are approaching from the East/West!" When the Pirate Invasion has reached the spawn point, a message will send, saying "The Pirates have arrived!"

During the event, six different enemies themed around a pirate crew will spawn:
 * : A simple enemy. Very similar to the Goblin Peon.
 * : A pirate enemy who carries and shoots a gun.
 * : Similar to the deckhand, but a little faster with a little more damage. He carries the Cutlass.
 * : Similar to the Goblin Archer. She carries a crossbow that seems to resemble one of the repeaters obtainable during hardmode.
 * : 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.
 * : A flying enemy that seems to spawn near the Captain.
 * : As of 1.3 a flying pirate ship boss was added to the event. It has four cannons with individual health bars that must be destroyed to defeat the ship. It also spawns many of the normal Pirate Invasion enemies.

During the event, the track titled "Boss 4" will play, and upon defeating the Pirate Invasion, a message will appear stating that "The Pirates have been defeated!" As of 1.3, the Pirate Invasion has its own unique track.

Defeating the Pirate Invasion unlocks the Pirate NPC, which will arrive during daytime if the player has an available house.

[[File:Extra 12.png]]Pumpkin Moon[[File:Extra 12.png]]


The Pumpkin Moon is a challenging Halloween-themed gauntlet that can only be summoned at night with the Pumpkin Moon Medallion. Unlike 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 are 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-caliber monsters, so it is not recommended for players to summon the Pumpkin Moon until they have end-game weapons and armor and well-reforged accessories.

The Pumpkin Moon has seven monsters, in increasing order of difficulty:
 * : The most basic monster, it slowly walks or hops about.
 * : A slow but resilient monster that is highly resistant to knockback.
 * : An extremely fast Wolf-like creature.
 * : A floating monster that passes through walls like a Wraith.
 * : The first boss-type monster, it passes through and climbs blocks and shoots volleys of fireballs.
 * : Another boss-like monster; it is similar to the Unicorn, but takes no knockback and is much more dangerous.
 * : The strongest beast of the Pumpkin Moon, Pumpking is similar to Skeletron and has three modes of attack based on which face it is wearing.

The Pumpkin Moon used the "Eclipse" music track, but got its own in 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.

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 an additional five "bonus waves" after the "Final Wave". Enemies have similar behavior to Pumpkin Moon counterparts, but are tougher, making this event the hardest as of Terraria v.1.2.4.1.

It has 11 types of enemies:

Added in the 1.3.0.1 update. The Martian Madness event is Post-Golem. 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.
