Dark Auction

The Dark Auction occurs every three in-game days at midnight or approximately 5 minutes before every real hour (ex: 1:55, 2:55, etc.) (a timer can be found here). The NPC Sirius appears in front of an iron door in the wilderness at the coordinates.

When Sirius appears at the iron door of the Dark Auction house, players must click on them to enter a queue for the Dark Auction. Sirius only allows players in that have a lot of coins in their purse, so players should bring as much money as they can. The Dark Auction only allows a certain amount in, allowing the richest in first.

If the player is not rich enough, they will receive a message telling them they need to meet the money threshold of at least a certain amount of coins (dependent on the individuals in the queue for the Dark Auction), and will not be able to warp in. If the player successfully makes it in, they will be warped to another server into the house. Players can go behind the desk to go down the stairs and enter the Dark Auction room.

After buying a certain number of items from the Dark Auction the player can talk to Lucius about purchasing / upgrading a special accessory.

Process
After 45 seconds of preparation, Sirius rains potions from the ceiling, causing all players to appear invisible. An item will be presented and will be showcased for five seconds. Players will then be able to place bids.

Similarly to the Auction House, the highest bidder wins the item. However, the Dark Auction follows a different system to the Auction House. Auctions only last for ten seconds, but the timer will restart each time a bid is placed. Additionally, players can only bid predetermined amounts of coins by selecting items displaying possible bids from a line, replacing the item with the player's head. Players can not bid lower than the highest bid, and any invalid selections are marked by barrier blocks.

Similar to the Auction House, money is immediately removed from the player's purse on bid, but it is refunded if it is not the highest bid.

There will be 4 items (7 items if Scorpius is mayor) all using this format. Once the Dark Auction is over, the back door will open and allow the player to walk back up to the house, and will later be teleported to the Hub Island.

Auctioned Items
The following items are all presented at random in the Dark Auction: Items can only appear in certain positions of the Dark Auction's order. Despite some items appearing multiple times in the order, Sirius will only sell a maximum of one of each possible item per Dark Auction. they will also not sell two pets of the same rarity but can sell two pets of different rarities.
