Molars

Molars is a common lobbed weapon in the Bone set — 1 damage, 10-20 uses, reaching targets up to 5 tiles away. At that damage value it isn't a real combat weapon, but that's largely the point: its lob trajectory and long range make it ideal for triggering on-hit ally abilities like Thorns or Hulk Up from a safe distance, since those abilities respond to any hit regardless of damage. You can activate them repeatedly without wasting high-damage weapon swings.

Blacksmith pushes it toward infinite uses while gradually adding damage. Dual Wield adds a free second projectile per use, and Robot Arms adds a second throw per turn. Obtained through the Hollowskull event; Pliers used against enemies have a chance to drop additional copies.
