Reborn Fortitude

You've gained the resilience of some undead, such as a zombie, allowing you to shrug off injuries that would have been lethal. You gain the following benefits:

• Increase your Constitution score by 1, to a maximum of 20.
• If damage reduces you to 0 hit points, you can make a Constitution saving throw with a DC of 5 + the damage taken, unless the damage is radiant or from a critical hit. On a success, you drop to 1 hit point instead.
