  You deprive a creature of the blissful oblivion of unconsciousness, either to keep it going despite grievous injuries or to prolong its suffering. For the duration of the spell, the target gains the Ferocity ability (Pathfinder RPG Bestiary 300), allowing it to remain conscious and continue fighting even if its hit point total is below 0. The target is still Staggered and loses 1 hit point each round, and the target still dies when its hit point total reaches a negative amount equal to its Constitution score.
