Jewel Of Vision?

Ok, I have to ask this, because I'm about to finish my MNK AFv3+1 head and I want to be able to get to work on the +2... does anyone have an idea where I would have to go to get the 6 Jewel of Vision that I need for it? I didn't see any info about where they drop from Wiki, but I've seen Screenshots of people rocking AFv3+2 heads for other jobs (like SAM) that use the same item for their +2 trial

they got from highest tier nm's in new abyssea zones. wiki & bg have all the info on all mobs that they can be got from

All head-related gear upgrades come from Abyssea - Attohwa. For Jewels of Vision, you'll have to defeat the NMs:

- Titlacuaun (Corse NM, popped with Blotched Doomed Tongue, Cracked Skeleton Clavicle, Writhing Ghost Finger and Rusted Hound Collar)

- Ulhuadshi (Sandworm NM, popped with Mucid Worm Segment and Shrivelled Hecteyes Stalk)

Thanks you guys, greatly appreciated
