Start by fading into the shadows with an Evasive Shadow Sneak to avoid that thunder wave. It can't hit you because the ground you're now part of will insulate the attack. Then use Shadow Punch to get some damage in. Finish the round with Rock Tomb. If we can make him slower, it'll be to our benefit.
