Benefit: Whenever you fail a Strength check (for bursting through a door for example), you gain a cumulative +2 bonus on your next try of that single Strength check. Whether or not the check succeeds, the strain to your body deals you some damage. You take cumulative 1d6 points of damage for every failed Strength check after the first. Check table below for clarification.
