Hi, i was looking into the Ars Nouveau mod and i saw the entry for the Source gems, in there it says that the ore its a little more common than gold, this means that you could find it pretty easely and therefore its used a lot in many recipes for the mod. The problem is that with Emendatus Enigmatica the chances of finding the ore are 0.05%, lower than diamonds. I dont know if this is an intended feature of the modpack but it makes the progress of Ars Nouveau way more difficult.
