Ashes Auction is a custom system that adds server-generated auction listings from virtual expeditions. These expeditions do not spawn visible monsters and do not drop items on the ground. Instead, the server periodically simulates a hunting run, collects the loot that would have dropped, and lists selected results in the auction house under the expedition name.

For players, the result is simple: the auction house can contain items sold by expedition sellers rather than by another character. You can bid on them, use instant purchase when available, and receive won items through the normal auction keeping flow.

The auction system runs an expedition roll pass once per hour.

Each pass uses the active expedition list:

• Only expeditions with a chance above zero are active.
• Active expeditions are kept in a rotation list.
• The server checks the rotation list in order.
• The first expedition that passes its chance roll becomes the successful expedition for that hour.
• A successful expedition is removed from the current rotation list.
• When every active expedition has succeeded once, the rotation list is rebuilt.

This means one lucky expedition can return during a given hourly pass, while the rotation prevents the same successful expedition from permanently crowding out every other active one.

When an expedition succeeds, the server looks for monster spawn centers near the expedition's configured map position. It then simulates a fixed hunting session from those nearby monsters.

The simulation uses normal monster drop data:

• Candidate monsters come from spawn centers around the expedition location.
• Monsters above the expedition's level range are filtered out.
• Spawn groups with more monsters have more weight in the virtual hunt.
• The expedition simulates 300 monster kills, matching one hour at one kill every 12 seconds.
• Normal item drops are rolled from the selected monsters.
• Drop groups are resolved into real items before anything is listed.
• Invalid or missing item templates are skipped.

The expedition is virtual from the world view. You will not see these monsters, dropped items, or expedition NPCs appear on the map.

Ashes Auction uses the live server rate settings when it rolls virtual drops.

The item drop roll includes:

• The monster's normal item drop chance.
• The current item drop rate.
• Party drop scaling when the expedition is configured with at least two party members.
• The configured party drop rate and party-size step multiplier.

Gold and chaos rolls are also simulated with the current gold and chaos drop rates. These gold and chaos rolls are not listed as auction items, but they matter for dungeon tax.

If the virtual hunt selects monsters from a dungeon that has an owner and tax rate, the simulated gold and chaos drops can grant tax to the owning guild treasury.

This mirrors the side effect of live dungeon loot without creating visible monsters or world drops. If a dungeon has no owner, no tax rate, or no qualifying simulated gold or chaos result, no treasury tax is added.

After the virtual hunt finishes, matching item drops are aggregated by item code. Each aggregated item then rolls the expedition's insertion chance.

If the insertion roll succeeds:

• Stackable items are listed with their aggregated quantity.
• Non-stackable items are listed as single-item auctions.
• The expedition name is used as the system seller name.
• The listing is registered as a system-owned auction.
• The auction duration is rolled as short, medium, or long.

Not every simulated drop becomes an auction listing. The insertion roll is a second filter after the monster drop roll.

Ashes Auction prices are built from the item's base resource price and the expedition pricing rules.

Pricing priority is:

The final unit price is the item base price multiplied by the selected pricing multiplier and the expedition's additional price multiplier.

The auction then rolls its starting bid from a range around the reference price. Some listings also receive an instant-purchase price; others are bid-only.

• Check auction seller names. Ashes Auction listings use expedition-style names rather than normal player names.
• Treat instant purchase as optional. Some expedition listings will have it and some will not.
• Bid carefully on rare drops. The starting bid is randomized, so similar items may appear at very different prices.
• Remember that listed quantity matters. Stackable materials can appear as larger bundles, while equipment and other non-stackable items appear one at a time.
• Watch for server notices. When an expedition returns, the server announces that its loot has reached the auction house.

Ashes Auction does not mean monsters were killed by a real party. The expedition is a server simulation using real drop tables, live rates, and configured expedition rules.
