Transmog Tokens

[Mozzarela]

Hello,
I got Transmog Token but I´m not sure how can I use it.. If I try to use by itemID, it writes me that I don´t have required Arena rating. Can somebody explain me how to use Transmog Token?
Thank you very much

you need 1 token to buy 1 item from "Transmog Npc" but you will also need arena rating.

You can still get the item you want without rating if you are lucky enough to get it randly from "Arena Case" ( or getting it from other players since item dropped from "Arena Case" are tradeable)

how you know the rating that you need ? thanks
