Periapt of Wound Closure

Attunement: Yes
Source: Level Up A5E

Engraved with symbols of healing, this warm silver pendant prevents you from dying.

While wearing this pendant, you automatically stabilize when dying. You may still roll your Death saving throw to try and roll a 20, but may only roll once on each of your turns and no more than three times.
Whenever you roll a Hit Die to regain hit points, you regain twice as many as normal.
