I've finally reached the final boss of the DLC, after 70+ hours spent playing it and checking every corner while at it. This is the point I need to admit: this is hard. I had fun listening to all the crybabies complaining about the difficulty of the Dancing Lion (first try for me), Gaius (10 tries), Bayle (12), Messmer (13), but this looks like a different story. It's actually so hard I'm not sure I will be able to go through it solo
26 attempts and I'm not even getting close, unless I'm missing something obvious here. The second phase is just WTF.
