A Paladin, a Bardo and mage/cleric or sorcerer.

I have been thinking about the Summoner Party idea.

3 is not enough! I would add one more.

A Jester. His song does the party no good right? WRONG! His song would keep monsters fighting each other and reduce the damage on your summons. At least in theory it would work.

It would be like a traveling circus! Animals! Music! Bad smells! Confusion and chaos! Crime! (Well you have a few pickpockets... What's a circus with out a little filching? ) Strange sights and fireworks!

Crap. I hate multiplayer games because of the loss of interaction, but, I might have to try this my self.
