Yamato

Necromancy Cast Time: 1 action Range: Touch Components: V, S, M (a shard from a kiln) Duration: Concentration, up to 1 minute Effect: You touch a creature, heating their body from within like clay in a kiln.

On a successful save, they take half the initial damage and avoid the ongoing effect.
