Reverberate
2nd-level evocation
Casting Time: 1 action
Range: Self (15-foot cone)
Components: V, S, M (a metal ring)
Duration: Instantaneous
You strike the ground with the metal ring, shaking the earth ahead of you with the impact. Creatures and unattended objects touching the ground in a 15-foot cone emanating from you take 4d6 thunder damage and fall prone; a successful Dexterity saving throw halves the damage and prevents the creature from falling pone.
At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d6 for each slot level above 4th.
