Rusty Armored Bones

Rusty Armored Bones are post-Plantera Hardmode enemies that spawn in the Dungeon after Plantera is defeated. Similar to Angry Bones, they come in multiple forms, follow the Fighter AI, and can open doors after a few hits. They can also inflict the Bleeding debuff for 10 seconds /. They are much more common in Dungeon areas with Slab Walls.
