Wave of Wrath

As you hold your weapon (or shield) aloft, a blast of intense rage shoots forth in front of you. Each creature in a 30-foot cone must make a Will saving throw. A creature takes 4d4 psychic damage on a failed save, none on a successful one.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 2d4 for each slot level above 1st.
