The Marketplace, Duendel's Shop and Nino's Shop are places you can buy consumable items as well as sell your unused in-game items.
As of v0.5.0, a number of items will be moved from Nino's Merchant Shop / Duendel's Shop to the Consumable Marketplace, a DAPP that runs outside the game. This means that players will be able to buy items using $GINTO (and other paired currencies) while not playing the game.
Players may spend a significant portion of their time off-battle in this shop screen as they can mix and match equipment to build a party with synergizing skills. Players can also sell of their discarded items for Perlas.
Every Tuesday and Friday (GMT+8) from 9AM to 9PM, a special shop keeper makes an appearance in the game lobby. Players can spend currency to exchange for rare crafting materials and other perks.
As of v0.5.0, Duendel will now sell rare crafting materials. Other items have been moved to the Consumable Marketplace.
