A supplement for fourthcore adventures that adds powerful, dramatic rewards and equipment for players and Dungeon Masters.

Many also provide narrative abilities, such as stealing a monster’s body or instantly raising crops across a valley. The collection is designed to complement standard treasure while offering more prominent and complex options.
