Ok..so I got a little confused about which quest was which.... only trying to be helpful.... people make mistakes. :/ guess mine was posting at all. It was the quest before this I was thinking about...getting the water from giddeus.
This is cheap enough from ah, around 1k at windy ah in Titan.
It cannot be enhanced or crafted. The Windurstian Gi and Fed. Gi are crafted from Mercenary's Gi, a rank 2 windy CP item. The recipe should be something like: Earth crystal, Grass thread, Grass Cloth, Mercenary's Gi. (use the same items for the other parts in the mercenary's set ie. Merc Kyahan -> Windy/Fed Kyahan)
