Blindness/Deafness

2-level Necromancy

You can blind or deafen a foe. Choose one creature that you can see within range to make a Constitution saving throw. If it fails, the target is either Blinded or Deafened (your choice) for the Duration. At the end of each of its turns, the target can make a Constitution saving throw. On a success, the spell ends.
At higher levels: When you cast this spell using a spell slot of 3rd level or higher, you can target one additional creature for each slot level above 2nd.
