Events

Events are occasions which can be activated by using an item or at random over time. During these events special enemies will spawn and certain aspects of the game may change during the period of the event. At the moment, there are 4 events, not including random "Boss Nights".

Blood Moon


The Blood Moon is an event that has a 1 in 9 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 increases as well.

During a Blood Moon Zombies, Werewolves and Possessed Armor can open doors. In Hardmode Clowns can spawn and all Bunnies and Goldfish become Corrupt Bunnies and Corrupt Goldfish. The Groom also has a chance of spawning.

Deathweed will also bloom during a Blood Moon. In the 1.2 update, all water in the world turns to blood.

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:


 * Goblin Peon: A basic Goblin.
 * Goblin Sorcerer: A Caster-type enemy that fires a projectile which can travel through walls. It can teleport.
 * Goblin Thief: A quicker Goblin that can also jump higher than others.
 * 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.
 * Goblin Archer: A Goblin that shoots arrows at the player.

When the Goblin Army have 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.

Frost Legion


The Frost Legion is an event which is very similar event 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:


 * Mister Stabby: A Snowman wielding a knife.
 * Snowman Gangsta: A Snowman that inflicts ranged damage with a gun.
 * Snow Balla: 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 introduced with the 1.2 update. Before the event, you will be told the solar eclipse is happening. Be warned, the solar eclipse enemies can be very difficult, lower tiered players should be cautious! Note that during the eclipse, it will become very dark, only slightly better than night.

The enemies that spawn are very dissimilar:
 * Swamp Thing: A swampy creature that can run quickly.
 * Frankenstein: A zombie-like creature that has much more health than a normal zombie.
 * Eyezor: Much like the laser shooting twins, this zombie breed will fry your brain with a deadly laser!
 * Reaper: A dark creature that is similar to the wraith, except it has a scythe!
 * Vampire: A VERY fast flying creature that will land on the ground and suck your blood dry! These are the hardest creatures to deal with during this event.

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 send warning all players that "Pirates 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:
 * Pirate Deckhand: A simple enemy. Very similar to the Goblin Peon.
 * Pirate Deadeye: A pirate enemy who carries and shoots a gun.
 * Pirate Corsair: Similar to the deckhand, but a little faster with a little more damage. He carries the Cutlass.
 * Pirate Crossbower: Similar to the Goblin Archer. She carries a crossbow that seems to resemble one of the repeaters obtainable during hardmode.
 * 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: A flying enemy that seems to spawn near the Captain.

During the event, the track titled "Golem" will play, and upon defeating the Pirate Invasion, a message will appear stating that "The Pirates have been defeated!"

Defeating the Pirate Invasion is the main requirement for obtaining the Pirate NPC.

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:
 * Scarecrow: The most basic monster, it slowly walks or hops about.
 * Splinterling: A slow but resilient monster that is highly resistant to knockback.
 * Hellhound: An extremely fast Wolf-like creature.
 * Poltergeist: A floating monster that passes through walls like a Wraith.
 * Mourning Wood: The first boss-type monster, it passes through and climbs blocks and shoots volleys of fireballs.
 * Headless Horseman: Another boss-like monster, it is similar to the Unicorn, but is vastly more dangerous.
 * Pumpking: 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. However, trying to record itwith a Music Box will give you an Ankh Charm instead. 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.
