Help with completing the game.

Thanks, but I've already maxed out the magic skills for one of my archers and I'm equipping him with as much intelligence and magic gear as possible (he even knows all the spells for fire, water, and air magic, and I'm not leveling up his earth magic skills for some reason). My second archer has focused on both melee and ranged combat (basically, he's become a "Knight").
I'm currently in Darkmoor, leveling up by fighting harpies and ghosts. My mercenaries are also pretty good. One heals, and the other creates portals. So, we're doing pretty well. No complaints!
