Onmyo Burst Wave

1st-level evocation

Casting Time: 1 action

Range: Self (15-foot cone)

Components: V, S, M (a small jade disc)

Duration: Instantaneous

You emit a burst of focused energy in a 15-foot cone. Each creature in the area must make a Dexterity saving throw. On a failed save, a creature takes 3d6 force damage and is pushed back 10 feet. On a successful save, the creature takes half as much damage and is not pushed. The energy ripples with a vibrant glow, leaving traces of energy behind.
At Higher Levels: When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d6 for each slot level above 1st.
