Webber's Skull is an item used to unlock the Don't Starve: Reign of Giants character, Webber. It has a 5% chance to drop when any Spider dies, including variants in Caves and Ruins. It can also be dropped when any tier Spider Den or Spilagmite is destroyed or a Spider Queen is killed with the same chance. The skull will not drop if it already exists in the world or if Webber is already unlocked. Trapped Spiders will not drop the skull.
Burying Webber's Skull in a dug-up Grave will cause Webber to appear under a "spotlight" after the grave is struck by Lightning. He will then jump back down into the grave, disappearing, while 6 Spiders appear in his place. Webber is then unlocked in the character menu. The Spiders will be aggressive towards the player, though killing them is not necessary for unlocking Webber.
Webber's Skull will keep dropping as long as it hasn't been buried, but not more than one in each world unless the previous one is destroyed.
- Increasing the amount of Spiders and Pigs in World Customization can help with finding the Skull, since Spiders fighting with Pigs will be more commonplace, and each Spider killed by Pigs has a chance to drop the Skull as well. However, players would have to pay attention to all the battles around, since the skull isn't going to drop more than once per world.
- The addition of Webber's Skull makes Webber one of four playable character that is not unlocked via experience, the other three being Wes, Maxwell and Woodlegs.
- Webber's Skull will become "Ashes of Webber's Skull" (Ashes) when carried through the Teleportato.
