Have you tried this:
park one char at the far end of the corridor and send the other one in single mode until one mage spots you. Then run back and take care, he follows you => at the end of the corridor, he should be out of stamina and can be killed in melee. they're weak, if they can't run away and use spells from the distance.

Do you have a spiritual bark? And a weapon with crushing damage?
