So the quester who pops the NMs can easily "superkite" the WHM and RNG around the room with initial aggro while the rest of the party kills the THF. Because the kiter hasn't done anything to claim the kited mobs, a healer can cure them without pulling hate.
All melees should bring several hi-potions and/or max-potions and wear as much resist fire gear that they can find.
At low health, the goblins can use back-to-back Bomb Toss and Goblin Rush.
Killable duo by various 75 job combos. See talk page.
When all the Goblins are dead, head back to Qufim (re-examining the ??? does not seem to do anything), and upon zoning back to Qufim Island, you will receive a cut-scene and, finally, your Fighter's Lorica.

If multiple warriors with this quest active are in the alliance, the NM only have to be fought once.
