Divine Grace
If one embraces death in order to regain life, then they will be given what is called Divine Grace or just Grace after resurrection. One can also acquire this through other means, such as leaving one of the arenas. Walking in the grace of the Gods means one cannot harm, or be harmed by an adventurer and most (but not all) denizens. To end the protection of Divine Grace, one can RENOUNCE GRACE, or simply wait a short time, after which Divine Grace will end naturally.
