So 3 Fading Bottled Faeries in the right combination will make 1 Weak Bottled Faerie.
Right at this moment the Fading Bottled Faeries go for anything between 4300 and 5000 except for Dark which hovers around 8000. The Weak Bottled Faeries go for approximately this:
So there's a possibility for profit.
I've tried several combinations, so far it comes down to choosing 3 different ones with a random result.
For example: water+earth+light -> earth
water+earth+light -> air
So if you want to mix your own, choose the cheapest of the fading kind, dark isn't necessary in my experience, and hope for the best!
* I named the topic ... recipes but this is incorrect as I can supply you all possible combinations and still wouldn't be able to predict a result so I left my findings out, my apologies for giving a wrong impression.
** There is also another new bottled faerie I'd missed earlier: Unidentifiable Weak Bottled Faerie currently going for 18-26k
