Celebrationmk10



Celebrationmk10 is a secret world seed included in the 1.4.2.3 update. It is accessed by entering the following code into the 'seed' box when creating a world:


 * Seeds (case-insensitive):

This seed celebrates Terraria's tenth birthday, May 16, 2021.

Overall

 * The spawn point can be on the left or right edge of the world, implying most of the spawns usually happening in the inner third of the world will happen in the left or right sixth of the world. So, for instance, Goblin Scout s will spawn in the middle of the world, while the Martian Madness event will only occur near the ocean you spawn in.
 * Andrew the Guide, Whitney the Steampunker, Yorai the Princess, a Party Girl, and an Angora Town Bunny will also spawn there and a Party immediately starts.
 * A majority of the world is painted: The Dungeon is in deep pink, Living Trees, the Pyramid, and Clouds on Floating Island are painted in pink, the Jungle Temple is painted with purple tiles and cyan walls, and all Sand Blocks, grass, and surface objects are painted in cyan.
 * There are even more Living Trees than in a drunk world.
 * Items in Chests always have a "best" modifier.
 * Accessories will have one of the +4 modifiers (Lucky, Menacing, Quick, Warding).
 * Weapons will have modifiers with the most stat increases, according to their damage type. The possible modifiers are:
 * Legendary, Godly, or Ruthless for melee weapons
 * Unreal, Demonic, or Ruthless for ranged weapons
 * Mythical, Demonic, or Ruthless for magic and summon weapons
 * Note that this generation is beyond the "modifier limit". For example, it is possible to get a flail with the Legendary modifier, which is impossible in a normal world.
 * Half of the Underground Cabins have their tiles and walls replaced with Rainbow Bricks, and a half of the remaining ones are painted with a diagonal rainbow pattern.
 * Gem Trees are more common, similarly to the drunk world.
 * All Floating Islands have Hallowed grass and a Hallowed Water Fountain.

Desert

 * The Desert generates without its usual entrance but with a single Pyramid.
 * The Chest in the Pyramid always contains a Pharaoh's set in addition to its normal loot.
 * The caves of the Underground Desert are smaller.

Other changes

 * Two unique enemies can be encountered in this seed:
 * The Jungle Mimic can be found in the Hardmode Jungle.
 * Golden Slimes can rarely spawn.
 * Fairies are less rare and most of them are Pink Fairies.
 * Uncommon and rare enemies seem to have a higher spawn rate.

 * Fireflies and Butterflies are more common.
 * The chance of obtaining a developer set from a Treasure Bag is doubled, and developer sets can be obtained from any Treasure Bag.
 * The chance for nights with an increased Fallen Star rate is doubled.
 * More clouds spawn in the background and more of them have a special shape.
 * The Steampunker and the Princess can always spawn.
 * Every non-corrupt tree grows as a vanity tree.
 * Most bosses (including the Celestial Pillars and the bosses' minions, but except the Leeches, Servants of Cthulhu, King Slime, Queen Slime, Plantera, Golem, Betsy, Lunatic Cultist, and the Moon Lord) are smaller than normal.
 * The Traveling Merchant always sells 2 more items than normal.

 * Flask of Party
 * Sandstorm in a Bottle (while in the Desert)
