Just got a Malachite to drop with a 32 amber level. Didn't see anyone post what amber level you should have to get this to drop, so i figured It would put it up. Hope it helps.
Used in the quest "An Offer You Can't Refuse".
Trade to Garnev in Abyssea Attohwa (F-8) for an augmented Elite beret, and 0-1 head seals for either BLM/NIN/COR/DRG.
