Bad Blood

Targeting a creature you can see within range, you attempt to corrupt its blood. Creatures without blood are immune to this effect.

The target must make a Constitution saving throw. On failure, they take 1d12 damage and become poisoned for the duration. Any movement also becomes difficult terrain under this effect. On a miss, the blood of the targeted creature instead burns with rage, providing them with an additional action on their turn.

At the end of each of its turns, the target can make another Constitution saving throw. On a success, the spell ends on the target, on failure, they take an additional 1d4 poison as the poison continues to ravage them.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, you can target one additional target for each slot above the 2nd level. The targets must be within 30 feet of each other when you target them.
