Ring of the Soul Harvest

Ring - uncommon - requires attunement

This ring has a design of a sickle and wheat at the top. Reversing the ring shows a design of longboats sailing toward a sunset, representing the afterlife. While wearing the ring, you regain 1 hit point whenever a Small or larger hostile creature is slain within 30 feet of you, provided that you're not unconscious and the creature isn't a construct or undead. You can't regain more than 1 hit point per turn in this way.

A harvest always takes one life to sustain another. Whether it be wheat from the field or animal for the slaughter, we all eat from the Reaper's silver platter.
