Describe the problem. Be as specific as possible!:
The Phantom skill, Carte Blanc, acts very much like final attack, but it only has a chance to activate after critical hits. The skill activates just fine, however, the skill doesn't actually deal damage like it's supposed to. It does actually display damage, but that is all it does. I've tested it on several monsters that should have died in one hit from Carte Blanc, but their health bars weren't displayed and they didn't even seem to be agroed by the attack.
