When you cast a spell with a duration other than Instantaneous targeting an ally, you can take a Bonus Action and expend one Battle Die to give that ally Temporary Hit Points. The number of Temporary Hit Points equals one roll of the Battle Die plus your Intelligence modifier. These Temporary Hit Points vanish when the spell ends.
