Dungeons & Dragons 2024 (D&D) Feat: Toughness (Combat)

An intrinsic hardiness marks you as one born for battle. Your Hit Point maximum increases by 1, and it increases by 1 each time you gain a level.

Extra Tough. If you take this trait twice, your Hit Point maximum increases by 2 instead of 1, and it increases by 2 each time you gain a level.

Additionally, when you make a saving throw against an effect that would decrease your Hit Point maximum, you have Advantage on the save. You regain the use of this feature when you finish a Long Rest.
