The Auction House can be used by all players to buy and sell goods. It is only available while in Flarine.
Non-bound items such as gear or consumables can be put on sale for a specific price in Diamonds.
Only Diamonds can be used to buy items at Auction, the Soulbound Diamonds given away in-game can't be used in order to avoid abuses or exploits.
For players who do not want to purchase Diamonds, auctioning valuable items is a good way to get some free Diamonds!
Upon sale, a commission will be deducted automatically from the sale price.
Note that the Auction House only involves trades between players, as such the Game Masters can intervene if any issues arise. We'd also strongly advise against putting items at auction for a very low price in order to trade them between players, as you will face the risk that another player purchases it first!
