You cause your weapon to ring with the powerful force of thunder as you strike your foe.

The first time you hit with a melee weapon attack during this spell's duration, your weapon rings with thunder that is audible within 100m of you, and the attack deals an extra 2d6 Sonic damage to the target.

Additionally, if the target is a creature, it must make a Strength saving throw, potentially knocking a creature

Prone

Success. The target is unaffected.
Failure. The target is knocked Prone or pushed 4m away from you (your choice).
Critical Failure (–10). The target is knocked Prone and pushed 6m away, taking 1.5× Sonic damage.

At Higher Levels: Increase the damage by 1d6 for each spell level increase.
