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 7 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:
 * 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. Only difference is, instead of turning purple, it becomes bloody.
 * A potentially very dangerous enemy, it sends bombs flying toward the player.

will also bloom during a Blood Moon. They can be found in the Corruption 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. It uses the same soundtrack as The Underworld.

Goblin Army


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 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.

When the Goblin Army has arrived the "Boss 1" theme will play.

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).

Frost Legion


The Frost Legion is an event which is very massive event similar to the Goblin Army and 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.

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 enemies that spawn are as follows:
 * : A swampy creature that can run quickly.
 * : A zombie-like creature that has much more health than a normal zombie.
 * : 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.

The solar eclipse lasts an entire Terrarian day, so the only way to stop it is to wait it out. It is possible to skip this event by simply going underground and waiting it out.

Pirate Invasion


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 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.

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!"

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

Pumpkin Moon


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 is much more dangerous.
 * : The strongest beast of the Pumpkin Moon, it is similar to Skeletron and has three modes of attack based on which face it is showing.

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.

Frost Moon


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:
 * : Basic enemy found in the early waves.
 * : Another fighter-type enemy.
 * : Dangerous ranged enemies that shoot flaming arrows.
 * : Powerful enemies that come in two variants.
 * : Similar to Krampus and Nutcrackers, but stronger.
 * : Flying, bullet-shooting enemies, with high damage.
 * : Stronger version of Nutcrackers.
 * : Spawn rarely during the event, but fly at the player at high speed, making them dangerous enemies.
 * : The first boss found during the Frost Moon, which shoot pine needles and tree decorations at the player. Can get through walls to reach the player.
 * : The second boss of this event, that shoots bullets, rockets and presents.
 * : The final boss, the strongest of the event. It's very evasive, and has attacks which are hard to dodge.
