Yamato

Transmutation Cast Time: 1 action Range: 30 feet Components: V, S, M (a mason’s hammer and a rock fragment) Duration: Instantaneous Effect: Strike the ground with a mason’s hammer, creating a seismic shockwave that cracks the earth in a 30-foot radius around a point you choose within range. All creatures in the area must make a Dexterity saving throw, taking 4d8 bludgeoning damage on a failure, or half as much on a success. Additionally, the ground in the area becomes difficult terrain for 1 minute as jagged rock fragments protrude from the surface.
