High Lord Dagra Dai in Ninja Gaiden II, on Master Ninja difficulty, is the single most sadistic fight I have ever had in a game. The fight itself isn't too bad by that stage on Master Ninja since you've already beaten him 3 times previous to get to Master Ninja difficulty in the first place, it's the sections preceeding it that are a right bastard, because before fighting Dagra Dai, who imo is the hardest boss in the game, you need to fight and beat, without any breaks for buying items or upgrades, 3 other almost-as-hard bosses before him, so if you end up fucking one of those up, or hell even the tiniest errors over all 3, then you have no heals, resurrections or ninpo boosts for Dagra Dai himself which pretty much guaruntees you a 2 shot death.
Oh and did I mention that while fighting Dagra Dai there is a never ending supply of pain-in-the-ass Great Fiends who are constantly leaping on you and bashing your face, picking you up and blasting demonshit at your face, or just plain ol' getting in the way so that Dagra Dai can pwn you in the cheapest possible way...in the face.
Yep. It sucks.
