Sudden Death A 9% chance to allow the execute ability after any hit. It's effect will not damage like an execution on targets less than 20%, but can crit up to 6500 (at least 20% of target health).

This was apparently in like patch 3.0.2, when I didnt play a warrior. Would this be a viable substitution for the sudden death we have now, since CS got nerfed? Or this could be our mastery?
