In one trip to the market i bought the Dwarven Blacksmiths Pack, Court Jesters Hat, and Witch Hunters Potion of Rust. She had the Thiefs Jacket equiped. I played the Jesters hat on her Paladin, played the Backpack on my Necromancer copying her thieves jacket and destroyed her thieves jacket. She cried foul saying that since the jacket was destroyed the backpack couldnt copy its abilities. Needless to say I changed my strategy and played the jester hat on her Paladin, the backpack on her bodyguard(copying the jesters hat) and destroyed her thieves jacket. She didnt like that either.
I just have to say that if I didn't already have the game, a scenario like the one described would have made me run out and buy it. I love games like this.
