Black Sand

Black sand threads up a creature you can see within range. It engulfs the target, filling their lungs and eyes. Make a ranged spell attack. If the attack hits, the creature takes 4d8 necrotic damage. On a hit, the target must also make a CON save against your spell save DC. On a failure, the target is blinded for 1 minute. It can repeat the save at the end of its turns. Roll a d100 as well.
