Concussive Blast

You brandish the weapon used in the spell’s casting and make a ranged attack with it against one creature within the weapons short range of you. On a hit, the target suffers the weapon attack’s normal effects and then becomes sheathed in concussive energy until the start of your next turn. The creature is incapacitated until the start of your next turn.

This spell’s damage increases when you reach certain levels. At 5th level, the ranged attack deals an extra 1d8 force damage to the target on a hit. The damage rolls increase by 1d8 at 11th level (2d8) and again at 17th level (3d8).
