One use only. The bearer becomes Daemonic and follows all of the rules outlined in the Bestiary section. If the bearer is the army's General, he must lead a daemonic army. Remember, a daemonic character cannot join non-daemonic units. At the start of the battle he must take a Toughness test (remember that rolls of 6 always fail). If the test is failed, the bearer reduces his Wounds and Toughness by -1.
