Well i like how you have to find a pattern in the game and try a few times untill you find the correct one, however i never really figured out how to do the jigzaw puzzle as it would not complete by itself :/
If you get "Frozen Diamonds", "Sword of Winter" and "Frozen Stone", if you then get a litle Splash Damage, and some Crit Rate + Crit DMG, You have the best Epic set, in game, i easily completed both Normal, and Nightmare, went to Hell, and got bored, BUT!, maybe il check back later :)
