Blade & Soul’s dungeon loot auction system allows the team to choose from several looting methods: round robin, free-for-all, master looter, and the default gold bidding. The gold bidding is a unique one that you can barely find in other MMOs.
The mechanic of gold bidding is simple: everyone in the group has the ability to bid for an item, and bids happen in minimum increments until the timer runs out or everyone passes on submitting a bid. Once an item is won by a person in the party, the amount of gold they bid and paid for it is equally split among the other group members.
The simple rules make many players neglect the mathematic behind it. If you played in other versions before you may know that. This is mainly for new players.
For instance: a boss drops item A *4 and the lowest price you can buy item A in auction house is 10 silver.
If you pay 40 silver to win item A *4, you earn the items you want with the lowest cost. On the other hand, each of the oter 3 players earn 13.3 silver. Assuming the other 3 players also want item A, they can puchase 4 of that item from auction house for 40 silver but since they’ve earned 13.3 in the dungeon, their actual cost is 40-13.3=26.7 silver.
So theoretically, you pay 40 silver for item A *4 in the dungeon while others just have to pay 26.7 silver for item A *4 in auction house.
Conclusion: your bid should be 3/4 of the auction house price unless: 1) you have lots of gold; 2) you don’t think you can buy the item at auction house in the lowest price; 3) you don’t want to waste time in auction house.
