 Here's how to get all six forms of Rotom in Pokemon, Scarlet, and Violet. Step 1. Catch Rotom. This is the spot I caught mine. They are also located around lighthouses in these locations. If it doesn't show up, just walk away and come back until it respawns. Step 2. Now that you have your Rotom, you can head over to the Auction House in Porto Marinanda to find a vendor that is selling the Rotom Catalog. Remember, Auctions unlock after you beat the Water Gym Leader. If the Rotom Catalog doesn't show up, save your game, go to Settings, and skip a day. Repeat this as needed. Step 3. Open up your key items, select the Rotom Catalog, and choose what you want to what form you want your Rotom in your party to be. Subscribe and tell someone...
