Goblin Masks?!

[FFXITsukasa]

Ok, Lv 29 Alchemy and I need to make Artifical Lens. I dont feel like wasting away all my gil buying Glass Fiber so does anyone know what Goblins drop Goblin Masks, please keep in mind im only level 51 Black Mage.

any of the buggers that have the leather mask+goggles appearance would drop it, i.e. ambushers, thugs, gamblers, leechers, etc. it's a crappy drop rate tho

[Gman]

Pretty much any of the gobbies that arent in the Black armor have a chance to drop it. Gobs that have no chance would be Fishers, Tinkerers, Butchers, Smithys, Reapers, etc...

If you watch your AH carefully you can usually buy them for ~400-600. Even if you fail 50%, if you do them on the right day (IE: Lightning, Light or Earth day) you should still come out ahead because of HQ. I found Windurst Ah to be the best for prices and availability followed by Sandoria and then Bastok. Bastok tends to have higher prices so I usually didn't bother looking.

It may seem like a bitch but honestly its faster than farming them.

Try goblin fishers, diggers, thugs and weavers. they drop a few.

A fairly comprehensive list of the goblins that drop Goblin Masks can be found here: http://ffxi.somepage.com/itemdb/display-item.php?item=3603

As a black mage of your level, you shouldn't have any problem farming a large number of them.
