Crimera

The Crimera is technically the Crimson variant of the Eater of Souls and as such, behaves in the same manner. It will fly toward the player, sometimes circling it at a set distance before rushing toward it. Since they spawn frequently in the Crimson, they can be great for obtaining Vertebrae or making farms. They are immune to the Confused debuff.

Spawning
It spawns only in the Crimson biome and in several varieties with different sizes that has different amounts of health, strength and defense.

Trivia

 * The Crimera's name is a portmanteau of crimson and chimera, a mythical beast made of parts from different animals.
 * It appears to be made of a silverfish (body), leech (mouth), and a bull (horns).
 * It somewhat resembles a Wrinkler from the game Cookie Clicker.
