Storm Diver's Additions Mod/Eye of the Dungeon

The Eye of the Dungeon is a pre-hardmode accessory that is dropped from Cursed skulls. It makes spinning bones spawn from the player that travel a short distance in any direction. They deal 20 damage to enemies and can hit multiple times each, but fade away after a very short time.

Trivia

 * This was the first accessory to be added, but it used to only provide a damage buff.
