Concussive Blast

You unleash a small burst of concussive force around you, forcing all creatures within range to make a Constitution saving throw. On a failed save, a creature takes 1d6 thunder damage and cannot take reactions until the beginning of their next turn.

This spell's damage increases by 1d6 when you reach 5th level (2d6), 11th level (3d6), and 17th level (4d6).
