Demonic Barrage

You conjure a malevolent orb of fire and hate. You can pay the demon held within some of your energy to increase the potency of the spell. When you cast the spell, any number of willing creatures may expend a hit die to empower the orb. When all hit die are spent, the orb sends fourth an amount of bolts equal to the amount of hit die spent. Each bolt does 1d4 + 1 fire damage, cannot miss, and can hit different targets. You can only fire up to five bolts per casting of  the spell.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, you can increase the maximum number of bolts able to be fired by 5 for every level beyond 1.
