The limit of dil (in-game currency) you can have on your character is 1 billion. As the economy has grown and better, higher level items have come into the game, the 1b dil limit was becoming a pain as players were forced to use multiple characters to stash dil.
We are one of the very few private servers to offer this system! Sinan in Ardeca will sell gold bullion for 100m dil. He will buy it for the same price! You can stack gold bullion in your inventory so it doesn't take up much space!
