The Corruptianos is the most corrupted biome known. It is thought to be a combination of most dimensions and planets. In it, many of the mobs from most dimensions and planets will spawn. The spawn rates of the mobs with more shadonic features (Being in the Umbra kingdom, being able to shapeshift, etc.) have a drasticaly higher chance to spawn. It also has some unique mobs of it's own. When the player is in the corruptianos, the Mortem Grass acts much like Soul Sand, giving the mobs the ability to not burn during sunlight. Additionaly, it doesnt matter what time it is in the Corruptianos. Mobs will always spawn, even if the world is at noon. Sadly, Dreitharans are very common in this biome.
