Bloodwarp

One target within range is forced to make a Constitution saving throw. On a failure, they have disadvantage on attack rolls, and ability checks and saving throws that use Strength and Constitution, and take 1d6 Necrotic damage each time they fail one of these for the duration. On a success, they take 1d6 Necrotic damage, and have disadvantage on the next attack roll, or ability check and saving throw that uses Strength or Constitution.
