Augmentation Process
The Key Item:"Scintillating Rhapsody", obtained from the final Rhapsodies of Vana'diel Mission, must be obtained first in order to begin the augmenting process for these items.
To begin, speak with Oboro about the weapons.
You actually need to select the option, "About the weapons" in order to be allowed to augment!!
This requires you to go into the "Show me the List." option, and then select the option "About the Weapons" at the bottom.
Trade the iLevel 119 weapon and either a single Pluton, Riftborn Boulder, or Beitetsu to him to begin the process.
The initial type of stone traded to begin the augment process locks the weapon in to being upgraded only with that type of stone.
The initial stone is not counted toward augment ranks, but is consumed.
Pluton, Riftborn Boulder, or Beitetsu x299 are required to complete the augment process up to rank 15 augmentation.
Each stone increases augment by 20 rank points.
All 299 must be of a single type.
The type required matches the stone which the player traded to initially to start the augment process.
Though the item says augment path A, there are no other augment paths possible to take.
