Barrage - Shiverpeaks

I wonder if someone could direct me to some detailed information on the area and stats of the boss that you get Barrage from in the Shiverpeaks?

if i remember you get barrage from 'markis' at the end of the iron mines of molandune mission.

"Markis" - He is the boss of the Iron Mines mission. A Ranger. Pretty easy to beat, but he is gaurded by Jade Armors.

After many problems with lag, we finally got it. Thank you to all of you who helped (party members, forum goers).
