Blood Clots

Choose one creature you can see within 30 feet of you. That target makes a Constitution Saving Throw, upon a failure, the target know has disadvantage on all attack rolls, ability checks, and saving throws until the spell ends. The target gets to retry the save at the end of each of their turns or whenever they take damage.

When you cast this spell using a 7th level slot or higher you can target one additional creature for each two-slot levels above 7.
