When Jack of Blades disappears to find all of the spheres (I forgot what they're called) Heroes, Guards, and Guild Members will come to help you to kill all the minions, if you kill more than all of them combined you'll gain more exp if you kill most of them yourself, while minions are good blockers I suggest before you start your mothers quest to stop jack to stock up on will exp and go directly to the guild each time you have enough to get your lightning spell, assassin rush, and your fire ball and skill exps to max, if you're going for a melee fighter and only fight with physical weapons ignore getting skill points and only focus on will exp, get your lightning up to max its most important when defeating minions, if its at 4 you can target four minions at once whixch will help a great deal, if you just keep killing minions and other creatures
