I don't know if this has been asked before, but I'm throwing it out as a question.
According to the Collapse of the Republic Sourcebook the Duskblade has Pierce 2 and the Nightsister has a Talent known as Ichor Blade which adds Pierce 2 to a Melee or Brawl weapon. Would this be stackable?
I ask because I know you can't stack two armors, but you can increase with the various Armor Master Talents, so would this as a Talent work the same way?
