Bone Helm

The Bone Helm is an Expert Mode accessory obtained from the Treasure Bag dropped by the Deerclops. When equipped, it summons Shadow Hands to damage enemies. These shadow hands are spawned a distance from enemies before flying at them, piercing anything in their path including blocks. Their flight behavior mirrors the shadow hands found in the Deerclops fight, either flying straight or swerving harshly in flight.

Trivia

 * It is the third passively attacking accessory, following the Volatile Gelatin and the Spore Sac. Coincidentally, all of these items are exclusive to Expert Mode, but only the Bone Helm can be obtained pre-Hardmode.
 * Despite being an accessory, the Bone Helm's sprite will override any cosmetic in the player's helmet slot.
 * The tooltip is a reference to Willow's examination quote for the Bone Helm in Don't Starve Together.
