Booming Voice

4th-level transmutation

Casting Time: 1 action

Range: Self (30-ft. cone)

Components: V, S, M* (the hair of a howler monkey)

Duration: Concentration, up 1 minute

You transmute your own voice and turn it into a powerful weapon. As an action during the spell’s duration, you can release a booming shout. Each creature in a 30-foot cone must make a Constitution saving throw. If the creature fails, they take 4d10 thunder damage and are deafened. If they succeed, they take half of the damage and are not deafened. Deafened creatures are immune to this spell.

At Higher Levels. When you cast this spell using a spell slot of 5th or higher, the thunder damage increases by 1d10 for each slot level above 4th.
