If you fight malistare and your a death wizard its pretty hard since he can resisit everything amazinlgly, even tho if you put a death prisim on him still you only have about 6 at the most possible in your deck :x
About every 3 quests theres like a 15 floor tower that ONLY people who have beat it already can help you with it which is kinda hard since most of my friends only like working on there OWN quests
I used to whip through the game now i am getting stuck at every quest :(
