Vala's Red Powder

You release a swarm of flying red motes against a creature you can see within range. The target must make a Dexterity saving throw. On a failed saving throw, the target takes 5d10 fire damage and can't see you until the spell ends. On a successful saving throw, the target takes half as much damage, and the spell ends.

The target can make a Dexterity saving throw at the end of each of its turns. On a success, the spell ends.

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.
