I was playing as usual. When I got to the third scene where there's full of toxic fog and corrosive stream, I encountered this "werewolf creature" (don't know what this called in English, I'm not playing this game in English neither) and I killed it with my bow and arrow, so the execution animation didnt trigger. However, as the last enemy was slayed, the magical dome-shape screen didnt disappear as it normally did, and I found out the "werewolf creature" was lying down in the stream below. Seems like it had been knocked out, so I tried to give one more last hit to finish it off and surprisingly it failed; no matter what kinds of deadly skills I used it just could not die. I would like to attach a video for better reference.
