Strategy
You always want a Blm for these missions, or a Brd, I guess. Sleeping stuff helps a lot… An alliance of 12x 70s is more than sufficient for this mission. If you're careful you can likely get away with less.
Drake Fang is inside Zehrun Mines.
Anyway, after the talking, head to Kuftal Tunnel. Just inside there is a ??? by the edge of a roped-off cliff. Be careful because the haunts below can actually aggro you wben you're in the upper area. Once you've all "knocked the piece of wood off the edge" (cute eh?) head around below by hugging the left hand wall. Kill all the haunts you meet along the way because they'll link to the ghost NMs that you're going to spawn.
Note that there are two ??? down here. I don't know what the one on the right hand side is, but everyone I did this with said "don't touch it!"
Have someone tag the ??? which is directly under the cliff above to spawn 3 ghosts NMs. Kill them (look out for their AoE drain and curse abilities).
Naturally you have to make sure everyone touches the ??? after the battle for a very short cutscene.
Go back to Drake Fang for a final scene and Rank 9!
