So it looked like AoE attacks did damage (subterranean assault) but nothing else would touch him. There would be a slight animation start for my skills but then it stopped & used up my stam like I had used a skill. It's all in the video - https://clips.twitch.tv/EvilBigIguanaItsBoshyTime - is this a bug, or should I report this guy?
