Sorrows Furnace.

Ok..
I just started doing Sorrow's Furnace about 2 weeks ago. I dont normally go very deep into the place but a few times i have been totally ready and hopefull to kill the final boss. I have made it pretty far but every single time been stopped by the furnace gates (the doors guarded by the "Furnace Guardians"). Ihave had no problem killing the guardians, so, i am just wondering if anyone knows how to get through these gates. It is quite annoyiong getting that far then having to stop!

How do I get through the furnace gates?

if you are doing Final Assault quest, all you have to do is talk to one of those guys who follows you. I forget his name...its been awhile since ive done the quest. He will give you a barrel...drop it by the gate and it blows up....opening the gate.

k thx.
