Doomed A5E
A doomed creature dies at a time determined by the Narrator, or within 13 (2d12) hours.
A doomed creature continues to be doomed even after it dies. Magic equivalent to a 7th-level or higher spell can remove the doomed condition (such as regenerate cast on a living creature, resurrection, true resurrection, or wish).
