Finding Barrage

Hi, I don't know whether to post topics like this here or not cause I'm new to this forum but not the game. So here goes.

I'm a ranger and am trying to find the elite skills; Poison Arrow and Barrage.
Can anyone please help tell me where the boss of these skills are? Any help would be appreciated, thanks.

I think it would go in the arcane repository but barrage can be obtained from markis in the iron mines of Moladune mission just make sure to kill him First then the jades so that u have enought time to cap it.

The char ranger boss in pre-searing has barrage. :P
