Timothy, if your fight took place in Salvatore's novels, then Drizzt would fling a few daggers into your mage, dive into a forward roll past the flailing mass of summoned creatures, shred Minsc with hardly a thought along with any other tanks, then end the life of your entire remaining party. Being an intelligent warrior, he would probably evade the summoned monsters, knowing that they would dissappear before long.
Oh, and he wouldn't be alone. He may just fight the summoned monsters, knowing that Cattie-Brie will plug your mage full of arrows from her hiding spot
