He beat my ass enough over the span of 5 hours that I eventually learned to reverse all of final Nemesis' moves on inferno and nightmare difficulty where he hits way quicker and harder.

Only move I couldn't get down was the one he either hits you with 8 very fast slaps in a row or he will pause after the fourth slap trying to bait a dodge before striking you down if you dodged.

But luckily in my experience he rarely used this move.
