Question regarding Freelancers and Swordplay

[Viladin]

Had another question from the same player, he's still tweaking his build.

What bonuses apply to Holy Sword Techs and Dark Sword Techs? He figures that universal damage boosters would apply but he's curious about things like weapon enhancements or the Temper spell, or anything that would boost melee attacks in general. He says that he'll understand if the answer is "no," but it's best to be sure.

The only techs that would get a boost from weapon enhancements or anything else that would boost melee attacks are the ones that actually deals weapon damage. Like, Doomslayer's Slash from Dark Knight.
