Benefit: A rogue with this ability can cause living opponents to bleed by hitting them with a sneak attack. This attack causes the target to take 1 additional point of damage each round for each die of the rogue’s sneak attack (e.g., 4d6 equals 4 points of bleed). Bleeding creatures take that amount of damage every round at the start of each of their turns. The bleeding can be stopped by a DC 15 Heal check or the application of any effect that heals hit point damage.
Special: Bleeding damage from this ability does not stack with itself. Bleeding damage bypasses any damage reduction the creature might possess.
