Radiant Sphere

3rd-level evocation

Casting Time: 1 action

Range: 60 ft. (10-foot radius sphere)

Components: V, S, M* (phosphorous powder)

You release a burst of blinding radiant energy condensed into a 10 ft. radius sphere centered on a point within range. Each creature within this sphere must make a Dexterity saving throw. On a failure, a creature takes 6d8 radiant damage and is blinded until the end of their next turn. On a success, the creature takes half that damage and is not blinded.

Any creature not within the 10 ft. radius sphere but is within a 20 ft radius of the center of the sphere must succeed on a Constitution saving throw or also be blinded until the end of their next turn.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d8 for each slot level above 3rd.
