D&D token (the pit) detail

A D&D token (the pit) is an item gained from the Squeal of Fortune, granting the player an extra game of The Pit and its corresponding reward. To claim your reward, simply use the token, and talk to the Talent scout at any agility course (except Burthorpe where there is none). Only one such token can be used each day.
