In the upcoming version update, the intricate augment system will receive an expansion. Previously excluded in the initial update, higher level equipment will now be available to augment from elite training regimens in Fields of Valor. In addition, the ever vigilant Sprites and Pixies in the past have taken it on themselves to challenge adventurers with notorious monster battles, with brand new rewards awaiting those willing to test their mettle.

Hear ye, mighty champions of Vana'diel!
Have you gazed longingly at the augmented apparel donned by your lower-level peers, wondering when similar equipment would be introduced for those of powers puissant?
Consider your wait over! A host of new augmented items designed especially for high-level characters will be one of the many exciting additions in the upcoming version update.

Further Fields of Valor!

Elite training regimes will be added to the following areas:
Cape Teriggan / Eastern Altepa Desert / The Sanctuary of Zi'Tah / Ro'Maeve / Yuhtunga Jungle / Yhoator Jungle / Western Altepa Desert / Valley of Sorrows / Ru'Aun Gardens

Thus far, Elite training regimes have yielded augmented items intended for players level 50 and below. Those who demonstrate their valor by completing the new regimes in the fields above, however, will be rewarded with a new selection of augmented items suited for levels above 50.

A New Challenge Awaits!

The greatest heroes and heroines of Vana'diel—those who have achieved the pinnacles of their respective professions—can also look forward to a new quest that will test the limits of their prodigious powers, and promise rich rewards in kind.
With hordes of fell beasts threatening their ancestral homelands, the pixies would entreat your aid. By entering into a pact with the fey folk to slay one of their notorious foes, high level players will have the opportunity to obtain an augmented item to add to their arsenal.
While Fields of Valor and the elite training regimes offer quick, straightforward objectives that can be enjoyed by lone wolves, this new quest is intended to provide a significant challenge to full parties of up to six veteran adventurers.

To participate in this quest, players must first craft a suitable weapon via a set of new recipes that will be introduced in the coming version update. Entrust one such weapon to the new quest-giving NPC and successfully complete the assigned task, and your weapon will be retuned, freshly endowed with an augment of impressive potency. Should the initial enchantment not be to your liking, you will also have the opportunity to slay a different foe—up to a maximum of five times—to receive a new augment that may better suit your needs.

This quest will offer something for everyone, as each member of the victorious party who has accepted the quest will be eligible to reap the augmented reward. Even players who have not accepted the augmentation quest will be compensated for assisting fellow adventurers with a bounty of their own.
