Druid: Nature Boon: Timeless Body

 

Timeless Body

Sustained by the living nature, your body does not perish easily, granting you the following abilities:

          When you are reduced to 0 hit points and are not killed outright, you can choose to drop to 1 hit point instead. Once you use this ability, you can't use it again until you finish a short or a long rest.

          When you roll death saves, you regain 1 hit point and return to consciousness whenever you roll as success on the save.

          Additionally, you suffer none of the drawbacks of old age, and you can't be aged magically
