Open Wounds (Rank 4)[]
The Garou may cause the next wound he inflicts to bleed profusely, weakening the target further. A pain-spirit teaches this Gift.
System[]
The player spends one Gnosis point and rolls Strength + Medicine (difficulty 7). If the Shadow Lord's next attack does any damage, the target will bleed continuously, losing one health level per turn for a number of turns equal to the number of successes rolled. This hemorrhaging is considered lethal damage.
