Forvengwath is a mini-boss in Barad Gularan. He's easy to get to, easy to defeat, and easy to re-set. He is, therefore, also rather easy to farm.

Forvengwath drops two great teal weapons. They are Bane of Forvengwath (not linkable for some reason...) and Forvengwath's Despair

These are great items for a hunter or lore-master. Here's how you get them:

You need a group: 5 will do, but you need a minstrel. Travel to the fortress of Barad Gularan. The gate you need to go through is on the South side of the fortress. You will pass drakes getting to it, but the way you know you're at the right one is that there are 3 gertheryg immediately to the right of the door. They can easily be avoided by staying against the left wall approaching the gate.

Enter, and you'll fight 3 spirits. After defeating them, a gate opens ahead. You'll see Forvngwath standing at the end of a large room, over some grates that lay over hot lava. Kill the adds on the left and right side of the lava area before aggroing Forvengwath. Then, when this is done, go to the middle of the lava area, the fellowship should stand on the strip of brick in the middle, which avoide the fire damage from walking over the grates. The tank goes forward and pulls Forvengwath, brings him to the group. Some adds spawn, kill them and the boss.

To re-set, leave BG through the door you came in. You must disband fellowship, then re-form. This will re-set the instance. Go back in, rinse repeat until you get the drops you need.

This is an easy kill, and each kill can be done in about 20-25 minutes. The bow and staff do NOT drop every time, in all likelyhood you'll need to kill him several times to get what you want.
