Core Splitter

You bring out both hands as they charge up a devastating attack. An enormous cone of fire bursts from your arms up to 60ft. in front of you. Every creature in the cone must make a Dexterity saving throw. Each creature takes 5d10 fire damage on a failed save, or half as much damage on a successful one.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the damage increases by 1d10 for each slot level above 4th.
