Gilded cabbage

The Gilded Cabbage is an optional item obtained after the Death of Chivalry quest. After the quest is completed, it can be looted from one of the coffins in the room where you fight Dawn, the final boss of the quest.

After kicking your own Gilded Cabbage a certain amount of times, it will say, "All hail Brassica Prime," and grant the player an additional 10,000 bonus prayer experience. The player will then receive a chat head from Brassica Prime himself!
