Trian's Holy Flare

A bright streak flashes from your pointing finger to a point you choose within range and then blossoms into a blazing radiance. Each creature in a 20-foot-radius sphere centred on that point must make a Constitution saving throw. A target takes 4d12 radiant damage on a failed save and is blinded for the duration. At the end of each of its turns, the target can make another Constitution saving throw. On a success, the spell ends on the target.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the damage increases by 1d12 for each slot level above 4rd.
