not sure what u have in mind with parry on your char using mage weaps...
point is: u need 80 dex for parry for being 100% effective. I suppose you want to run a mage template, therefore u will waste a lot of stats to dex to get your parry run. further, if you happen to become cursed, u will fall back far beyond 80 dex. therefore, u need high magic resist OR chiv OR have to chug pots/eat apples.
Second: U can use mage weaps BUT u will fail to use special moves if u don't have the weapon skill also (and tacs, of course). Therefore u get the active (chance to hit the enemy with your weap) and passive (chance to be hit by the enemy) weapon skill effect, but not the specials.
what do you have in mind to do with your template?
