There's something wrong with the stylish executioner, I found myself didn't go invisible after a stylish execution, if you watch the clip, the melee damage is still amplified, but no invisibility is granted after that. This invisible thing is like a gamble, sometimes it work (https://youtu.be/VydU-YokK_I), sometimes it doesn't. I also found out that this only applies to those who are one-shotted by the powered melee, if the melee doesn't kill it will be weakened. Any help is much appreciated.
