Cauterize
At 2nd level, you learn how to use caustic and flammable reagents to seal a wound so that it can be cared for later. As an action, touch a creature. That creature gains temporary hit points equal to half their missing hit points plus your Intelligence modifier (minimum 1). In addition, if an effect, such as bleeding, would be removed by healing granted, cauterize ends that effect. These temporary hit points last until the next time the creature completes a short or a long rest.
Cauterize has no effect on constructs, undead, or creatures with immunity or vulnerability to fire damage.
Once a creature has benefited from cauterize, that creature cannot benefit from it again until they have completed a long rest.
