Thicken Blood

You attempt to slow a creature by thickening its blood. Choose one creature with blood that you can see within range. The target must make a Constitution saving throw. On a failed save, the target’s movement speed is halved, and it takes a -2 penalty to AC and Dexterity saving throws.

The target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. Creatures without blood are immune to this spell.

Blood Sacrifice. When casting this spell, you take 1d4 damage as you manipulate the target’s blood.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, you can target one additional creature for each slot level above 1st
