Vallhallan's Death Curse by Rakino[]
When you would roll your Last Breath as a result of combat, don't. Death's Gate is closed to you. You're still unconscious, wounded, injured, or otherwise in a bad spot but you don't die of those injures. Just as normal, you'll need nursing, healing etc to recover. You're still perfectly capable of dying in any way that would not get you entrance into Valhalla - poison, old age etc.
