How to Get Rotom Pokemon Brilliant Diamond & Shining Pearl
To get Rotom and change its forms in Pokemon Brilliant Diamond & Shining Pearl or BDSP, the first step is to beat the Elite Four. You can’t get it to spawn before that. Next, make sure that you have the Cut hidden move in order to remove certain trees. If you’ve defeated the Elite Four, you probably have it already. Now, go west of Eterna City onto Route 205. When you cross the bridge, head up and left into Eterna Forest. Go a few more steps to the left, and you’ll see a white picket fence with trees blocking the entrance. Use cut to remove them and go into the haunted mansion, aka Old Chateau.
Head up the stairs and then go through the doorway in the middle. In the next corridor, head left and into the second door above you. You’ll find yourself in a room with a TV, and that’s the Rotom Location in BDSP. Before doing anything else, make sure that the time on your console is past 8 PM, and absolutely save the game. Only then should you interact with the TV and make the Rotom spawn. If you mess it up, just reload the save until you manage to grab it. That’s how to catch Rotom in Brilliant Diamond & Shining Pearl.
How to Change Rotom Form Pokemon BDSP
To change Rotom form in Pokemon BDSP or Brilliant Diamond & Shining Pearl after you get it, you need to pick up the Secret Key. You’ll get that item after you catch Rotom; it’ll drop the item as soon as you catch it / defeat it. You will automatically pick the key up, so don’t worry about that. Now, head back to Eterna City and go into the Galactic Building. That’s the high-rise with spikes that’s behind the Pokemon Center. Cut the trees blocking access to the road and go inside. On the ground floor, head into the upper left corner, to the wall left of the bookshelves.
Tap A while facing that bit of wall, and you’ll uncover a secret room. Go inside and inspect the random appliances. Professor Rowan is going to come in and explain what the appliances are for – basically, you use them to change Rotom’s type. For example, the washer gives it water powers, the microwave fives it fire powers, etc. Feel free to experiment with it. By the way, to get more Rotom, you can breed it with Ditto.
