Blue 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. Blue Armored Bones have a 50*1/2 (50%) chance to inflict the Broken Armor debuff for 10 seconds / 20 seconds.

They are much more likely to spawn in Dungeon areas with Brick Walls.
