==Events==

===Seasonal events===
Tied to the date in real life instead of anything in-game, seasonal events cause changes that aren't vital for game progression but often have exclusive items. Some add enemies/enemy variants, some allow certain enemies to spawn in more places, and two historical ones even had unique bosses tied to them.

Modern versions feature only two seasonal events, both of which can also be manually triggered for an ingame day if certain conditions are met (see Pumpkin Moon and Frost Moon below):
*Halloween - Pumpkins naturally grow without having to be manually planted, Ravens spawn everywhere (not just Graveyards) at night, Ghosts spawn naturally underground, and Hopping Jacks (think big pumpkins that want to kill you) spawn in Hardmode. Enemies drop Goodie Bags with Halloween-themed loot being obtained from them. Some critters and enemies gain Halloween variants, which are basically them wearing costumes. Goes from October 10th to November 1st.
*Christmas - Enemies drop Presents, which contain Christmas-themed loot. Most notable of which is the Snow Globe in Hardmode, meaning the ([[Derp|underdeveloped]]) Frost Legion event is technically locked behind the Christmas season. Some enemies and critters have festive outfits. Goes from December 15th to 31st, and goes out with a bang (literally) by exploding Santa.

Older versions (particularly old console/mobile ones) have a few more:
*Valentine's Day - Worlds generated during this event can contain a Heart Shrine in the Snow biome which allows players to obtain the normally post-Plantera Frozen Biome Chest early - the chest contains several love-themed items (including [[PROMOTIONS|69 coins]]) and the shrine itself also has two Life Crystals which grant 40 extra max HP total. Gems broken during this period have a chance to drop a Cupid pet, and the Merchant sells an accessory and special arrows. Lasts the entirety of February. Still available on Windows Phone and 3DS, with the Heart Shrine oddly only being present on the former.
*Easter - A new enemy, the Diseaster Bunny (ha), spawns if Lepus hasn't been defeated yet. These enemies (alongside Corrupt Bunnies if Lepus hasn't been defeated) are the only way to obtain the Suspicious Looking Egg to summon the boss. Lasts the entirety of April. Still available on Windows Phone and 3DS.
*Thanksgiving - The Merchant sells a pet turkey, and enemies have a chance to drop Cursed Stuffing. Committing animal cruelty using both is the only way to fight Turkor the Ungrateful. Lasts the entirety of November. Still available on Windows Phone and 3DS. (Noticing a pattern yet?)
*St. Patrick's Day - Rainbow pieces fall from the sky during the day (basically Falling Stars but in the sun) and can be crafted into a leprechaun pet. Lasts the entirety of March, and is only still available on Windows Phone (it was never available on 3DS, strangely enough).

A Chinese New Year event was planned for the Mobile version but was scrapped when Re-Logic made the decision to remove content not made by them in the modern console and mobile versions. It would have given the Wyvern a dragon puppet variant among other things.

Several of these removed events, alongside other removed console/mobile-exclusive content, are added back in by mods.

===Blood Moon===
At night, monsters come out. Zombies and Demon Eyes, mostly. On a Blood Moon, a somewhat uncommon event, evil is stronger; the Zombies and Demon Eyes hit harder (and sometimes mutate into abominations), and the Zombies gain the presence of mind to open doors, and Female NPCs get grumpy towards you because...ahem. Encounters for all monsters skyrocket. Suffice to say, the Zombie apocalypse is on, and your NPCs are in jeopardy unless you built your base well. (Hint: Two-door "airlocks" work just fine, since zombies can only open doors inwards.)  Good training for the much more dangerous rigors of Sieges and PVP, Blood Moons give you a real taste of a sustained assault. You must hold the line until [http://www.youtube.com/watch?v=EjazC45Qkww the morning sun vanquishes the horrible night].

God help you when these happen on Hard Mode. And don't go fishing unless you want more nasties to fight, including a miniboss in Hardmode.

===Solar Eclipse===
Rarely, there will be a solar eclipse, during which vampires and Frankensteins come out to play. If and when this happens, it will suck, because vampires have 800+ HP, and hit like a pissed off angry marine. Have fun! Oh right, some of the zombies shoot lasers. Mostly based on monster movies.

You'll want to kill the Mothra clones for the Broken Hero Swords they drop, since otherwise you won't be able to craft the uber-swords locked behind the True versions of the Night's Edge and Excalibur.

===Goblin Siege===
Occasionally, a bunch of Goblin shits get together and decide to raid your village, putting you pesky humies to the sword. When this happens, the Goblins will march towards the center of the map and actively seek to occupy buildings and kill NPCs. Goblin Mages, siege engineers, and warriors will attack, and you must perform a veritable [[Exterminatus]] to kill them all, since the siege only breaks when so much time passes that they give up, they kill everyone, or each and every Goblin is killed. A Siege can be summoned by using a Goblin Battle Standard: which is crafted from 10 tattered cloth and 5 wood at a loom. Goblin Sieges are easy to dispatch if you killed a few and are holding spiked balls they drop, Goblins are incredibly stupid and will walk right into the spiked balls you set on the ground.

In Hardmode, they bring in their tougher, Shadowflame-addicted <s>Summoners</s> Warlocks. That can fly.

===Old One's Army===
A crossover with some tower defense game called Dungeon Defenders 2, and basically plays like one somewhat. Except you can fight the enemies in the waves head-on yourself if you want. Notably gets upgraded as you progress, first becoming available after beating the World Evil boss (being locked behind the Tavernkeep NPC that only spawns after you kill the EoW/BoC) and getting upgraded (in terms of difficulty and the enemies you'll have to fight) twice in Hardmode: once after beating a Mechanical Boss and then after Golem. There are 3 (mini)bosses, with 2 first appearing in a respective tier and later both appearing in the final one with the remaining boss. They're the Dark Mage (a book-riding necromancer first appearing in the final wave of Tier 1 and later in Tier 3), Ogre (a giant club-wielding cyclops, spawning in the final wave in Tier 2 and later in Tier 3), and Betsy (a dragon that spawns on the final wave of Tier 3).

Also notably the only event that forces you to build an arena, since a relatively large, flat area is required to summon the event by using an Eternia Crystal on its Stand, and also blocks building and breaking blocks as long as it is active. You can get some gear out of it, either from boss drops or buying it from the Tavernkeep using Defender Medals you can collect for beating waves. You get 5 Medals for free from said Tavernkeep at the start, so make sure you grab a basic tower from him to make your life easier.

===Frost Legion===
Hard mode equivalent of Goblin Siege (in a sense), they are only encountered in Hard mode and can only be summoned from a Snow Globe which is only attained through opening presents during Christmas (Dec 15-31). The Snow Globes can summon them regardless of season. However they are even stupider than Goblins since they can't break down doors, nor can jump down wooden platforms. There are 3 kinds, Snowman Gangsters (Gunners), Mister Stabby (Warriors), and Snow Balla (Throws snowballs which can wreck homes and can block up holes in the ground).

You get Santa Claus as a NPC Villager after defeating the Legion but will only show up between Dec 15-31. After the 31st [[rip and tear|he explodes into gore]].

[[Derp|The most underdeveloped of the bunch]] (seriously, why didn't they flesh it out in one of the newer updates), so don't expect much.

===Pirate Invasion===
Yet another hard mode siege, except not season-specific. Can occur on its own, but can also be summoned by use of a Pirate Map, a hard mode drop from enemies in coastal areas. Pirates are in almost all regards just souped-up goblins. Watch out for the Captains though, since they have 2000 HP, hit like trucks, and are accompanied by obnoxious attack parrots. Like the goblins, these guys are total morons, and can be defeated with a modicum of strategy even if you lack superior firepower. Pirates generally drop golden furniture, although they have some disgustingly rare drops that can be found nowhere else. Hope you like farming! They also have a flying battleship.

Defeating your first Pirate Siege will get you the Pirate NPC Villager.

===Pumpkin Moon===
A Halloween-y event that can only be initiated by use of the Pumpkin Moon Medallion, an item constructed from Pumpkins (which only grow around Halloween initially), Ectoplasm, and Hallowed Bars. The Pumpkin Moon lasts one night, and consists of up to 15 ball-crushingly brutal enemy waves that culminate in not one but two consecutive boss fights, against the Mourning Wood (yes, really), and the almighty Pumpking. You will not only have to focus on staying alive, but also on micromanaging the rate at which you kill enemies, so as to ensure that the event progresses to waves 14 and 15 before you kill the bosses; killing them any earlier drastically reduces the odds of them dropping some of the best loot in the game. So yeah, not only is it incredibly tough, it's finicky bullshit as well. Fantastic!

If you get to wave 15 (or the final wave, 20, in older versions), the normally season-locked Halloween content will become available for an entire ingame day.

===Frost Moon===
Like the Pumpkin Moon, but Christmas-themed and harder. Summoned with the Naughty Present. Proof that you can turn Christmas music into something badass. Has three bosses, the Everscream (Mourning Wood without the innuendo), Santa NK-1 (A Santa-themed mech bringing Christmas cheer...with guns), and the Ice Queen (a cold bitch). Has the same reduced drop rate bullshit in early waves for the bosses as the Halloween counterpart. If you get to wave 15 (or all the way to the last wave, wave 20, in older versions) you get a day of the normally season-locked Christmas content.

===Martian Madness===
An alien invasion caused by getting seen by a martian probe that you let escape. Hope you like getting probed. Drops gear that's useful for the final stretch of progression.

===Lunar Events===
If you kill the Lunatic Cultist, four Eldritch pillars - themed Solar for melee, Vortex for ranged, Nebula for magic, and Stardust for summoning - appear across the world. As they are the final event of the game, they are incredibly tough, summoning endgame-tier enemies that need to be defeated in order to attack their associated Pillar directly. Killing them drops endgame materials relevant for their associated damage class, and killing them all summons the Moon Lord.

Having one spawn over your base ''will'' kill any town NPCs that wander outside wondering what the strange lights are. Oh, and [[rape|don't fly near Solar]].
