Wolverine

"It is not by accident that the witchers have named this potion after an animal known for its fierce and aggressive nature. Wolverine unleashes the entire potential of mutation, turning the witcher into a dervish of destruction. Witchers use this potion when they are certain that Signs will not help them in combat."

The Wolverine potion increases the damage inflicted when a witcher's Vitality falls below half.

When albedo is used as the dominant substance the Wolverine potion increases the attack efficiency and damage inflicted by 50% (Vitality penalty required).
