Doomsday: Odysseus Returns Refinery Auction Card Trading Guide

To trade armament cards profitably in the Doomsday: Odysseus Returns Refinery Auction, purchase mispriced items carrying high-demand combat affixes, factor system transaction fees into your resale targets, and time your listings to close during peak server hours.

Evaluate Card Affixes and Demand

Market pricing depends primarily on secondary combat attributes rather than card grade alone. Cards with stacked offensive affixes sell for high values, while utility or defensive rolls trade near the system baseline.

• High-demand attributes: Squad Attack, Troop Lethality, Damage Reduction, and specialized troop bonuses (such as Infantry or Ranged damage multipliers).
• Low-demand attributes: Gathering speed, hybrid non-combat stats, and marching speed against infected.
• Stat synergy: An epic (purple) or legendary (gold) card with two matching offensive affixes regularly commands higher prices than a higher-tier card burdened with mismatched or utility stats.

Before setting a sale price or committing to a buyout, search the market for cards with identical secondary rolls to establish the current going rate. Do not rely on default minimum price suggestions.

Sniping Underpriced Buyouts

Sellers frequently post valuable combat cards at default minimum prices to clear inventory quickly. You can locate and buy these undervalued listings before other players spot them:

1. Open the Refinery Auction and filter by your desired equipment category.
2. Sort search results by newest listings rather than lowest bid price.
3. Check the listings immediately following daily server resets or right after competitive alliance events end, when players unload reward caches.

Purchasing these underpriced items allows you to secure cheap gear for your own squads or relist them at standard market clearing rates.

Account for Transaction Fees Before Reselling

Every completed sale in the Refinery Auction incurs a house transaction fee. Thin profit margins will be consumed by this commission cut, leaving your trading currency locked in low-yield inventory.

Only flip cards when the realistic resale price exceeds your purchase cost by at least one-third.

Auction Bidding and Listing Rules

Disciplined timing prevents wasted currency on purchases and maximizes returns on your listings.

Sniping Bids Near Auction Close

• Avoid placing bids hours ahead of the deadline. Early bidding alerts competitors and locks your currency in escrow.
• Add target cards to your watchlist and submit your bid in the final 5 to 10 minutes.
• If a competing bidder drives the price within 10% of the card's standard direct buyout rate, stop bidding and let the auction pass.

Setting Listing Prices and Durations

• Split pricing: Avoid setting the starting bid at your target buyout price. Set an accessible starting bid to attract early attention, paired with a realistic buyout price based on recent sales. Early bids build momentum that encourages bidders to compete.
• Server timing: Schedule your auctions to conclude during peak evening activity in your server's region, or align endings with the preparation and training phases of cross-server combat events when demand for combat armaments peaks.

Reinvesting Auction Profits

Do not leave trading profits sitting idle in your wallet. Direct your earnings back into account power by purchasing catalysts for refinery progression, securing blueprints, or unbinding key armament cards for your primary combat march.
