You can find the Auction House at Porto Marinada, west of the Pokémon at the top of the hill. When you reach this area, head down to the stalls in the market and see what the vendors have for sale. They will shout what they have for you to try and bid on. You want to find the person offering to sell a Rotom Catalog and then jump in to see if you can win the bid for the item. The goal is to outbid the other characters who want to buy it, but you also want to ensure you’re not bidding too much and overspending.
After you purchase the item, the Rotom Catalog will go into your Key Items. If you have a Rotom in your party, go to your Key Items bag option, click the catalog, and choose what transformation for your Rotom.
