14th-level Circle of Wildfire feature
The bond with your wildfire spirit can save you from death. If the spirit is within 120 feet of you when you are reduced to 0 hit points and thereby fall unconscious, you can cause the spirit to drop to 0 hit points. You then regain half your hit points and immediately rise to your feet.
Once you use this feature, you can't use it again until you finish a long rest.
