Color From Beyond

The caster makes a spell attack against a creature within range. A shimmering ray like a stream of rainbow colors strikes the creature. It suffers 5d10 acid damage. It then has to make a constitution saving throw against your spell save DC. On a fail, the creature is blinded for 1 minute. It can repeat the saving throw at the end of each of its turns to attempt to get rid of this condition.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d10 for each slot level above 3rd.
