floyd is right, single class clerics don't make good tanks as they only get one attack per round. that means they really don't do any serious damage to the enemy. and because they can only put one prof. point into two weapons style dual-wielding is not a really viable option.
so while they can drop their AC down to bellow -10 and can get reasonably good HP (about 130) they don't do much damage.
I'm currently playing with a kensai/mage and have only viconia in with me and I find that she hardly manages to swing the Crom Faeyr once before the main character minces the enemy into oblivion
