Bristle's Pain Transference

You sacrifice some of your blood to transfer your pain to another creature. You take 4d8 necrotic damage, which can’t be reduced in any way, and one creature of your choice within range that you can see must make a Wisdom save. On a failed save, the creature takes twice the damage you take as psychic damage. On a successful save, the creature takes the same amount of damage you take as psychic damage.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d8 for each slot level above 3rd.
