Toothpick

The  is a heavy melee weapon that deals a powerful hit if the attack button is held down for long enough. If the charged attack strikes an enemy, the Toothpick breaks and becomes much weaker for several seconds. This item is exclusive to the Rise of the Giant DLC.

Trivia

 * Because the blueprint for this item is only dropped by enemies within the Cavern, it is technically an item exclusive to the Rise of the Giant DLC, even though it was added to the game in v2.3, which was eleven updates later.
