[Wed Sep 27 00:35:36 2017] You begin casting Identify.
[Wed Sep 27 00:35:38 2017] Item Lore: Cloaks you in the appearance of a sarnak skeleton.
[Wed Sep 27 00:35:38 2017] This item gives positive faction to Brood of Di`Zok.
[Wed Sep 27 00:35:38 2017] This item gives positive faction to Empire of the Di`Zok.
Similarly to the Visage of Chardok Royalty, note the following:
You get the faction modifier while having this item equipped in your Face slot. It's not the illusion buff that gives the faction modifier, although the illusion may possibly have its own separate racial faction modifier that some illusions naturally provide towards some NPCs.
The scroll an enchanter gets for handing this in to Bindral Argaff is: Spell: Illusion: Sarnak Skeleton .
