Ravager

Not to be confused with sans.

The Ravager is a Hardmode boss that spawns alongside illagers during raids and can be fought anywhere on the Surface. On top of dropping a unique set of weapons and accessories, its purpose is to act as an efficient, though not necessarily easy, means of acquiring Life Alloys, Cores of Calamity, and other materials via Fleshy Geodes. It attacks players, adult villagers, wandering traders, and iron golems by charging, biting, and roaring at them. A ravager can sometimes become stunned if its attack is blocked with a shield.
