Finally got my Foestriker's Mitts! Ended up joining a lone THM in Tam-Tara who was at the very end of the dungeon. We killed a few of the remaining guards before a GLD joined us, then took on Octavel. We got through his fight without any issues, but halfway through the Mindflayer fight our GLD disconnected and the THM and I had to deal with the boss and its adds. I've gotta give credit to him: he was damn good at sleeping the adds and healing me until the GLD got back on. A CNJ joined us at the very end of the fight, but we finished off the final boss without their help.

I couldn't ask for a better way to earn 'em, either: helping out two new players =P
