Kuudra keys cannot be sold, auctioned or traded. The wiki lists them as Co-op Soulbound on pickup, tradable only to Co-op members, not on the Auction House and not salable. You get keys from the Mage or Barbarian Emissary shop, minibosses, Crimson Isle lava fishing, or by crafting four of one tier into the next. A Kuudra run needs the tier's key for the paid chest.

Steps
- Craft four keys of one tier to make one key of the next tier.
- Vanquishers drop Nether Stars, which the Emissary shop needs.
Against it
- The paid chest's value cannot be recouped by selling keys; you only profit from what the chest drops.
Tips from the sources
- The wiki page does not name the Bazaar; it only says keys are not salable.
- Infernal Kuudra Key from lava fishing is a very rare great catch (about 1 in 14,700 catches at base treasure luck, per the Crimson Isle loot table).
