Lost Ark Gold is a currency that you will require all the time, which will allow you to buy just about anything you desire from the Auction House, including equipment, skins, engravings, potions, and so on... but Gold will also be needed to strengthen your high-level equipment. In addition to this, it may be traded with other players, used to purchase Blue Crystals, and is required in order to raise the overall quality of your possessions. The fact that it takes a significant amount of time and patience to accumulate enough Lost Ark Gold to proceed in the game is likely to frustrate a good number of the game's participants. Because the amount of gold you have is directly proportional to how far you get in the game, you should put as much of it away as you can and put it toward improving your primary character.
