^ to elaborate... A fading bottled faerie is the old type that gave blessings in the old abilities system. They are no longer active, and will no longer do anything for your pet. The old abilities don't work anymore, they've been completely redone. You can take any three fading faeries and mix them in the cooking pot for a new (weak) faerie. These weak faeries in the shiny new bottles give your pet blessings that you can use at the abilities page in the new BD. That is... if you can get it to load. lol
The whole new faerie thing was quite a shocker for me when I got back. Didnt know about all this. Thanks for making the thread!
That or get 3 different ones and make a new faerie that you can use to train your pet. It's worth it IMO.
