Confirmation of Skullcap Quest Item Existing in P99?

[Manticmuse]

I'm hoping to gain some clarity regarding the final Iksar Necro Skullcap Quest, #8. Quoting the p99 wiki: Necromancer 8th Rank

The final Skullcap in the questline. Go talk with an Iksar hermit (located in a cave just before you zone into the LoIO from West Cabilis). He tells you he is looking for a great sorcerer and hands you a flaxen hilt with some slots in it. He then tells you what to put into those slots.

The items you need are: Flaxen Lock of Hair (drops from Chief RokGus in Frontier Mountains), a Yellow Whip (drops from a wulfware lonewolf in the Dreadlands near the FV zoneline), Large Tassel Bookmark (reward from The Tome Raider quest in Kaesora.

Combine these items to receive a new Flaxen Hilt and return to the Iksar hermit. Hand him the hilt and he will give you a Barbed Scale whip. Give him the whip and your skullcap and receive your Necromancer Skullcap.

What I'm confused about is the flaxen lock of hair that supposedly drops off Rokgus. It's not listed under his loot table, and none of the many people I have talked to that camp him have even seen it. So the real question is...can anyone confirm a drop of the flaxen lock of hair?

Thanks,
