...and I failed badly. lol. Act II was incredibly tough without the additional healing bonuses from items but still managed to finish it. It was the Act III's hydra warriors and abyss prowlers that ended my epic adventure. Playing on Rag'narok difficulty is almost impossible.
On the side note, the Bosses in Rag'narok difficulty are a bit too easy. I suggest giving the bosses some kind of AoE reduction debuff to make the fights more interesting.
