I think its possible to enter Stormfist Castle by level 3. If all you do is do the Orc quests without killing anything. What I'd like to know is if you never cure Madarious (sp?) well he show up cured in the later quests or won't he show up until he is cured?
My level 2 charactor got an Elemental Hail book which is a level 24 spell that would deal with just about anything in Rivertown, just a matter of having enough mana. So I can see where you could fly through the game with that, but not sure I see the point of it.
