The S's Sonic Boom

You feel your chest break open, as you unleash a 10 by 10 cylinder attack of directed sound toward one creature within range. The target must succeed on a DC 10 dexterity saving throw or take 1d8 force damage and become deafened until the beginning of you next turn.

Casting At higher levels grants additional damage dice, i.e. 2d8 at level 2, 3d8 at level 3, 4d8 at level 4, etc.
