I have whittled Yiazmat down to the last 2 or 3 bars of his health and I can't seem to keep my characters alive as his normal attacks will almost always instantly K.O. me. I've seen videos on YouTube where they never get KOed. Is there something that I'm doing wrong? I'm having to run out every 30 seconds or so and sometimes I don't make it. A little help would be most excellent.
