Corrupted Link

You touch a creature that has died within the last month. That creature returns to life with 1 hit point. This spell can't return to life a creature that has died of old age, nor can it restore any missing body parts. The creature also shares a unique brand on its forehead, showing it has returned to life. from this point onward the resurrected has a permanent link to the caster. If the creature this spell was used on dies, the 5 health points are returned to the caster, however, if the caster dies, all creatures connected take 4D12 Necrotic Damage.
