When you play assassination and you're a guy with dia gear, you probably get this. Today i had 18 stacks of dark coins in my inventory at ONCE. So i had no more place. Something like a coin trader in only ONE shop! Like potion shop so there's more people there. When you have 60 dark coins, u can trade it for 6 platinum coins or 12 gold coins. When you have 64, you can trade 60, but the last 4 wont be traded. Thanks for reading! reacht with your opinion too please!
