Diabolist

The Diabolist is a Hardmode enemy found in the post-Plantera Dungeon. It is most common in areas backed by Tiled Walls. These are identified by the related Faction Flag, the Diabolic Sigil.

Diabolists attack by firing blazing magic bolts that can travel through blocks at the player. Their magic bolts explode, creating an "inferno", a large flaming sphere that lasts for several seconds and deals massive damage on contact, inflicting the On Fire! debuff. Diabolists teleport to a different location on-screen every time they are hit.

 * Weapons that deal high damage in single hits are effective against Diabolists. Weapons that fire multiple projectiles simultaneously may be able to land multiple hits before they teleport as well.
