I have an accent problem. This is what I've bought in just the last week...
Ritual
Prestige
Memento (got two of these, need to find another dragon for it)
Chronicle (and have another one of these on the way)
Antique (have the female version of this but can't find a good dragon for it yet)
Arena
![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
Shadow and Neutral dragons give festival/chest drops and I think there's a 28% encounter rate in the Arena? Might be off on the percentage but it is highest there.
