Transfer Wounds

You redirect a portion of your pain back at your attacker. When a creature deals damage to you, you can use your reaction to channel that wounding energy. You reduce the damage you take by 1d4.

Choose a creature you can see within 30 feet. That creature must make a Constitution saving throw. On a failed save, it takes necrotic damage equal to the amount of damage you prevented. On a successful save, it takes half as much damage.

At Higher Levels: When you cast this spell using a spell slot of 2nd level or higher, the damage reduction (and subsequent potential damage dealt) increases by 1d4 for each slot level above 1st.
