Subclass featureValdaSpire242014Warmage

When you roll Initiative, choose a number of Allies up to your Intelligence modifier (minimum of one) within 60 feet of yourself that can see or hear you. Give each Ally a Battle Die without expending it.

Once within the next minute when the Ally fails a D20 Test, it can roll the Battle Die and add the number rolled to the d20, potentially turning the failure into a success. A Battle Die is expended when it's rolled.
