Full: Bring target dead party member back to life at full Health and full Energy. If you stop maintaining this enchantment or if this enchantment is removed, that party member dies and leaves an exploited corpse. Deaths while enchanted with Unyielding Aura do not incur a death penalty. (50% failure chance with Divine Favor 4 or less.)
Concise: Resurrects target party member (full Health, full Energy). End effect: this ally dies and leaves an exploited corpse. Does not incur a death penalty. 50% failure chance unless Divine Favor 5 or more.
There is no way to prevent the death caused by Unyielding Aura ending.
If the caster of the enchantment dies approximately one second after casting, the enchantment will never be placed, resulting in a full resurrection with no penalty for the resurrected player.
Ending this enchantment does not incur death penalty, just as any death while under this enchantment does not incur a penalty.
Bug! Sometimes, when a player is resurrected with Unyielding Aura, that player gets a massive white box instead of the normal head. This effect lasts until death and renews after getting resurrected again.
