Waking Death is an item in Tyranny.
Taken before falling unconscious, the spores of the Waking Death mushroom guarantee to revive the imbiber with a fraction of their full health. It's common enough for a soldier to feel outclassed by a foe. When there's a chance of dropping on the battlefield, Waking Death offers a second wind of energy - albeit at a reduced capacity. The imbiber is capable of staving off unconsciousness long enough to seek aid or press a desperate attack, which can make all the difference.
