Blue Armored Bones

Blue Armored Bones are Hardmode enemies that spawn in the Dungeon after Plantera is defeated. Similar to Angry Bones, they come in multiple forms, follow the Fighter AI, can open doors after a few hits, and are immune to the Poisoned and Venom debuffs. Blue Armored Bones have a 50% (1/2) chance to inflict the Broken Armor debuff for 10 seconds /.

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