I never did sneak during the whole game. I guess I didn't see the value at first, then forgot about it. I guess I missed out on another tactic.
Re ethereal magic, nice one. I couldn't figure out which magic was most effective against bosses, except for the hammer that almost never failed. With enough speed (30-35), a magician can hammer the boss quickly enough that he's always stunned.
For summoning dolls, I guess the final battle is definitely the only one where it kind of makes sense, but how powerful is it? I supposed you used the ranaar skeleton for that?
Final boss could summon allies? Heh, I never saw that.
