I don't know if this has been mentioned yet, I haven't seen it, but it would be awesome if there was a tab in the craft shop that showed us exactly what we have in storage!
And I'm curious, if I trade a dragon that is part light, will it make a white gem? It isn't needed for anything yet, but may be used on something in the future, and I would hope that it would save it for me until then.
We essentially have that functionality already. For any particular ingredient, you'll see a pair of numbers to the upper-left of the item, like 5/2. The first number is the total number you have, the second number is the number required in this recipe.
Small and Large Pearls can be obtained by trading white dragons and yes, they will be used in future crafting recipes.
As I understand it, they can go up instead of down. This has been designed this way to encourage longer play and something to do in addition to tending our dragons. Also, makes a challenge for the higher level players otherwise they would be finished and looking for more in just a couple days. So I understand the concept now.
Sorry if the answer is somewhere here but I can't trade common dragons. It only lists the ones I bred. However, a small yellow gem (required for a scroll) says to trade a common yellow dragon. Hmmm....so what's the deal with that?
You should be able to trade common dragons. The only dragons that can't be traded are single element. (Air and fire for example.) But you could trade in a fruitful and get a mystery box. The mystery box will give you a small gem (yellow or green) or some other craft material. Normally its the gems though.
Common hybrids are tradeable. Not the pure elements, like fire or water, but their hybrids, like coral or mist, and so on. Common hybrids will give you ONE small gem of one of their elements. Rare hybrids will produce two (or three if they're tri colors, like the super dragon, aurora or mirage) small gems and a mystery box (y0u can get another small gem, nether dust, or a scroll). Super rares will produce two large gems and a mystery box.
