Synthesis stones

So I think you should be able to make your own synth stones. One way I think this could be accomplished is a de-synthesis option. Now it would have to be different than being the opposite of synthesizing due to the fact that u would have to get a stone of that lvl that you are already trying to get, defeating the purpose. So I think you should be able to take one of every basic stone of the same lvl (power,attack,mana,def,crit,damage,and agility) put them together and sacrifice them for a synth of that lvl (max being lvl 4). It's just an idea I already posted this but I put it in the wrong section lol. Is this a bad idea?

It's great!
I've always needed a way of getting stones since I dont like coining em

This has been suggested before many times and in the last 2 updates it was no implemented :l

this will most likely never happen :l
