"Your weapon rings with thunder that is audible within 100 meters of you."
| Tier 1 | With your next attack, you can expend one spell slot to deal additional thunder damage to the target. The extra damage is 1d8 for each spell slot level. The target must succeed on a Fortitude saving throw or be pushed 5 meters away from you and knocked prone. |
| Tier 2 | A sphere of sonic energy explodes in a 5-meter-wide sphere. Each creature except you in the sphere must make the Fortitude saving throw. If the target fails, it's affected twice. |
| Tier 3 | A cone of sonic energy shoots out in a 10-meter-wide cone. Each creature in the cone must make the Fortitude saving throw. If a target is affected by the cone and the sphere, it's affected twice. The targeted creature is affected thrice. |
