Lately, I've been noticing that I have too many ecto drops, minerals, shinning fire crystals, eternal orbs of alchemy, inactive people on my friends list, and jelly gems, but not enough radiant fire crystals, energy, and crowns.

So instead of me going out and getting more of the currency I need as was originally intended, I was hoping for a new NPC in game that will take literally anything, and convert it into anything else. The rate of exchange should be around 5 of whatever I have to 3 of whatever I need, except for the first 3 transfers per day and in order to use this I must visit the arcade and complete at least 7 depths. The NPC will gradually give me better and better deals as I buy into this as well- at first, I will lose resources by swapping them around, but later on I will actually gain resources, eventually at a rate of 1 of anything to 10 of anything else that I desire, with no limitations.
