Lucanic Breastplate of the Knight. You will do fighter archetype line. The quest series is 3 parts, racial, archetype, and the main line. Look up Freeport Reborn on Zam
Stats on Zam are outdated. Would suggest looking at the BP on the Upgrade Merchant in the big tent, by Reforger. He will only show one BP.. your class. I hope its visable before you unlock purchase.
Stats on my scout version were in line with the Thur and Rygor pieces I had.
