Spiral Sphere

4th-level evocation

Casting Time: 1 action

Range: Self (20-foot radius)

Components: V, S, M (a spiral-patterned token)

Duration: Instantaneous

A swirling orb of force energy expands outward from you in a 20-foot radius. Each creature in the area must make a Dexterity saving throw, taking 6d8 force damage on a failed save or half as much on a successful one. The energy distorts space briefly, making the area difficult terrain until the start of your next turn.
