Spread

Main article: Biome spread

The Contagion spreads itself, similar to the Corruption, the Crimson and the Hallow. This means that it slowly converts certain susceptible tiles that are in the vicinity of existing Contagion blocks. While its spreading capabilities are very limited during pre-Hardmode, it spreads much faster and more aggressively after defeating the Wall of Flesh. Defeating Plantera for the first time reduces the speed of the Contagion's spread by 1/2 (50%).

Contagion Desert

In Hardmode, Contagion spreads through Deserts, transforming them into Contagion Deserts. A Contagion Desert is fairly similar to a regular Contagion biome: The theme music and enemies are the same, with the addition of:

Sand is replaced by Snotsand. Cacti drop ordinary cactus when cut, even though they have a different color. Waterleaf is unable to grow in Contagion Deserts.

Contagion Snow

Like the Contagion Desert, Contagion Snow biomes are created when Contagion spreads into a Snow biome during Hardmode. Snow Block is not convertible, but Ice Block can be converted into Yellow Ice Block. Yellow Ice can be created during generation if a Contagion biome overlaps a Snow biome, but it will not spread until Hardmode.

Notes

The tree icon of a world with Contagion in world selection menu (right: Hardmode world)
  • During the generation process of a world with the Contagion, the left half of the progress bar frame will be green, and the main progress bar will be lavender.
  • Contagion can be created or spread artificially using Contagion Seeds, Vomit Water, and either the Clentaminator or the Terraformer with Contagion Solution, obtainable from the Steampunker during a Blood Moon in Contagion worlds (she sells Purple Solution and Red Solution in Corrupt and Crimson worlds instead).
  • It is possible to create an artificial Contagion biome in a Corrupt or Crimson world without the use of another world. To do so, one must buy Contagion Seeds in Hardmode from the Dryad while in a Graveyard.
  • Artificially creating a new Contagion biome requires at least 300 Contagion tiles. Although Corruption or Crimson might replace Contagion at world generation, it does not prevent Contagion from being artificially created in a Corruption or Crimson world (and vice versa), nor does it prevent the Contagion biome's spread.
  • During Hardmode, any enemy in the Contagion or Underground Contagion has a 0.04*1/2500 (0.04%) chance to drop a Contagion Key.

Trivia

  • The music used in the Contagion was created by Turquoise.
