Sorry I have to make this quick since I'm halfway out the door, but basically, a ton of "Kusas" (NIN mobs in NIN AF) and Bhoots (named Kuga....something). The Kusas are true-sound, the Bhoots are regular sound.
There are 3 Kusa NMs, Saizo, Oko, and Danzo. Our second attempt we snuck past all the Bhoots and all the Kusas (except two that we aggroed), and killed the 3 NMs in that order. When Danzo died, a ??? popped below him. Clicking it wins the assault. 1999 with first win bonus. ??? necklace appraised to Phi necklace.
This is the map:

Start at G/H-10
Saizo at I-8
Oko at F-8
Danzo at G/H-8 (after going up the stairs west of Oko)
Drop from Danzo's room right on top of the Rune.
