Dauntless (5e Feat)
From D&D Wiki
Prerequisites: Constitution 13 or higher
You are well known for never giving up. In fact, you never compromise, even in the face of your own defeat. You gain the following benefits:
- When you start your turn, if you have no more than half of your hit points left, you gain 3 temporary hit points. You do not gain this benefit if you are unconscious or if you have not taken damage since your last turn.
- When you take damage that would reduce you to 0 hit points, you can use your reaction to bolster your willpower. You gain temporary hit points equal to 1d10 plus your level, which take as much of the triggering damage as possible. Once you use this feature, you must finish a short rest or long rest before you can use it again.
