tl;dr - basically shift-click crafting for spiral knights
As the title says, if you haven't noticed already fire crystal requirements at the forge goes up exponentially, so to level up a 4 star item form 7 to 8 requires 60 fire crystals ( http://wiki.spiralknights.com/Forge#Fire_Crystals_Requirements ), that'll be 12 crafts of shining fire crystal at a alchemy machine per level which doesn't seem to be a efficient way of doing things. When you use a alchemy machine it'll still look the same but have a box where you can input how many times you would like the selected item to be crafted, it'll then show you all the crafting requirements.
I don't see why this shouldn't come to be.
