Hadonami Beam

4th-level evocation

Casting Time: 1 action

Range: 60 feet

Components: V, S, M (a polished stone inscribed with waves)

Duration: Instantaneous

You unleash a powerful wave of energy in a 30-foot line that is 10 feet wide. Each creature in the line must make a Dexterity saving throw, taking 8d8 force damage on a failed save or half as much on a successful one. The wave leaves shimmering ripples of energy in its wake, marking the ground with faint light.
