Or a taney exchange. Since this game is not easy and has an expensive worth of donations. Let's not make it too simple and cheap. How about a 10pcs orb in exchange of 1 taney? It's not bad since the drop rate is medium and there are many green orbs around there. And this also to help donators to manage their taney freely. Good example is, I have 16,000 taney and a Power Weapon cost 17,000 taney each. I will just hunt or convert my green orbs(10,000pcs) to make up the 1,000 lack in my taneys instead of donating 6,000 taney. Of course there would be a limit per day, lets say 5,000pcs Green Orb to 500 taney is the maximum convertion, this is to control the taney and market in the game. Again, this is not a cheap, easy server.
