As long as you have 80 dex, you will not have any negative buffs to parry. If you don't have 80 dex you will have a penalty on parry. I don't recall how severe it is, but it hurts your chance to parry a lot. It'll be hard to fight without resist, especially once you run out of apples. My one bud runs this template and it actually does alright with him.

120 magery
120 eval
120 resist
120 parry
120 mace
120 med

he's working on gettin 80 dex, but runs with a diamond mace and uses concussion blow. He actually does alright. I personally think that weapon mages are faulty, cause if a dexxer disarms you, you're done, but that's just me. I play my dexxer pretty much all the time now, and I destroy weapon mages using this tactic.
