Stay in the middle at the top of the rig... you're going to have to just stand in the fire.
Use the Dome of protection/soothing presence/mend metal so that your armour and magic armour are regenerating.
Your guy should be smart enough to stay in the dome. Make sure you have a couple of characters who can cast fortify, and maybe magic shell.
Slowly but surely you should be able to pick off everything.
