This idea has come a long ways and I just though maybe if I share it the developers might see it and make use of it.
The idea is to convert a building where one could trade ingredients to gain other items. For example, trade 100 common leafs for 1 midnight root. I think you get the idea.
They can called it The Trading center or The Market, or whatever they want. It would definitely make the game a bit more fun.
They don’t need to make a trading center for ascension items, because they make a lot of money from it. So just the ingredients for crafting will do.
