Divine Radiation

When you cast this spell, a wash of energy expands from you in a 10-foot radius sphere, mirroring the general alignment and aesthetic of your deity. The sphere is centered on you and follows you as you move. Any creatures in the dome that make a saving throw or attack roll get 1d8 added or subtracted to the roll (the caster decides individually).

At Higher Levels. When you cast this spell using a 4th level spell slot or higher, the radius of the spell increases by 5 feet for each slot level above 3rd.
