Hell 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. Hell Armored Bones inflict the On Fire! debuff for 10 seconds / 20 seconds. They are visible in darkness, but do not actually emit light, except for a faint glow when immersed in water.

Hell Armored Bones are most common in Dungeon areas with Tiled Walls, as indicated by the Molten Legion Flags present within these sections.

Notes

Despite them being immuned to the On Fire! debuff, they still take damage from lava.
In the Getfixedboi and Don't dig up Secret world seeds, Hell Armored Bones will drop the Katana instead of the Keybrand.

Trivia

The Bestiary entry for the Hell Armored Bones: "The fiery glow of the Molten Legion is unmistakable. With their red-hot armaments in hand, they blaze a trail through all those in their way."
