Well, in Faerun mage slaying invidual needs GOOD reason slay mages and what is his views about it. As heroic invidual I asume you have something against about evil mages and you simply 'trained' yourself fight against them more better and you do not view your combat style no more different than learning how wield rapier more effectively.<br/><br/>Anycase I recomend you take Mage Slayer feats from Complete Arcana. Some of them are quite nasty ;). But otherwise I do not view the combo odd, I would imagine that a Sembian tutored finesse figther realized he faces alot spellcasters or mysterious power users so he decides it is benefitical to study fight against mages (because you lack your own magic) and you could view it as 'market hole' where many would hire a magic resilient mage/cleric slaying bodyguard.
