-Reserved Just In Case-

I appreciate this! (the purple is hard for me to read thought >.< maybe use light purple?)

I would like to know how to get the azure robes of the oracle. I see elder Orynn (? spelling?) wearing it, but of course one would not attack her to get it as a drop so... And there are none in the trade broker at the moment. If anyone has info, please and thank you!

You can't actually get the azure robes of the oracle in the game. According to Savynn (I believe), who has it from Krin, the item was coded but never given a place to actually drop.

Sorry. Meant to ping you in the above post. There was a discussion about the robes yesterday in the region chat.

Thank you, and that is very sad. Blue is my favorite color and that my favorite outfit. Perhaps after we are done with Astryl's Tranquility the elder person will give it to us? One can hope.

Edited!

I'm still looking for more info, so feel free to send me a PM! :)

The Conch Staff of Bubble and Water Pearl Wings are drop by Ariella in Astryl's Tranquility.
