Surviving crippling blows along slab dungeon corridors
Rusty Armored Bones make their lair exclusively in post-Plantera Dungeon zones backed by slab walls. Characterized by oxidized armor and jagged broadswords, these resilient undead boast 550 health in Classic (reaching 1,100 in Expert and 1,650 in Master). They hit fiercely with 70 contact damage, while introducing a crippling tactical threat: their strikes can inflict both Bleeding and the Slow debuff, severely dampening sprint speed and flight.
Gathering adhesive bandages for the medicated charm
Because the Slow debuff leaves spelunkers vulnerable to surrounding dungeon horrors, hunting Rusty Armored Bones is essential for status defense. They are the prime dungeon provider of the Adhesive Bandage, dropping at 1% to craft the Medicated Bandage and Ankh Shield. In addition to medicinal supplies, their loot includes the Morning Star at 0.5%, the Keybrand at 0.5%, the Magnet Sphere at 0.33%, the Bone Feather at 0.33%, and the Wisp in a Bottle at 0.25%.
Trivia
- Rusty Armored Bones spawn in the same slab-walled areas frequented by Ragged Casters.
- Equipping a Fast Clock or Ankh Shield completely nullifies the Slow affliction applied by their rusted weapons.
