Scryllar

The Scryllar is a Pre-Hardmode enemy that spawns in the Brimstone Crag. It is a ghostly figure that can travel through blocks. It will swoop around the player before moving in to attack. It also has two variations; the normal variant and the rage variant. While they have different stats, they both drop the same loot.

Its stats receive a significant boost and starts dropping Bloodstone after Providence, the Profaned Goddess is defeated.
