In my parties the cleric was always the only one using a blunt weapon for melee in Kresselack's tomb, only a part of the undead there are resistant to them and they still take half damage, most damage is dealed by ranged weapons (bow, sling) anyway.

The shield spell grants immunity to magic missile spells IIRC.

I have cleric, mage, bard and 3 fighters, that okay?

It's your game; of course it's ok.

Thanks! (:
