Augmentation (EFA - A)

You enhance the destructive power of the next spell you cast. If you cast a
damaging spell on your next turn, you add 1 point of damage per die to the damage rolled. If you don't cast a damaging spell on your next turn, augmentation dissipates.

At Higher Levels. If you cast this spell with a 4th level or higher spell slot, the extra damage increases by 1 for each slot level above 3rd.
