From D&D Wiki
Boon Of Second Chances
Give yourself a second chance in combat with ease
As an action, roll 1d20 and add your Constitution modifier plus your Nature modifier, gaining hit points equal to whatever you get from the roll. Any hit points over your maximum are instead turned into temporary hit points. You also gain resistance to the next damage type you take within a minute, and does not suffer damage from that one attack. You lose the damage resistance at the end of your next long rest. Once used, you cannot use this again until you finish a long rest.
