PC: Gold Firey Dragon Sword of Sowrdmanship

Gold
Firey dragon sword of swordsmanship:
fire dmg, req 10
15^50
swordmanship +1 (20%chance while using skills)

I found this in a tombs drop and was wondering what it was worth and if i should put a perfect defense mod on it?

wouldn't mess with the mod... may get 10-20k outta it but dunno

a perfect swordmanship is fine (is less commonly seen, and might catch more attention then armor) 15k+
