Blue Armored Bones

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, 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.
