Appendix:Diamond and Pearl walkthrough/Section 26

Eterna City

Fly to Eterna City. Head to the house in the southwest corner of the city, near the gate to Route 206 and Eterna Gym. You'll find Professor Oak inside and he'll give you an item Up-Grade. Let a Porygon hold if you have one, then trade it and it'll evolve. Next time you talk to him, he'll check how many Pokémon you have caught.

Make sure you bring a Pokémon with Cut and at least 30 Dusk Balls before proceeding! You must be playing at night or in the early morning (8:00PM-3:59AM, between 20:00 and 3:59 on your DS clock) in order to encounter a legendary Pokémon.

Route 205

Head west along the bridges on Route 205, into Eterna Forest.

Eterna Forest

Take a few steps east you'll see Gardenia looking at the Old Chateau. She greets you and asks if you've heard the rumors about ghost Pokémon living in the mansion. She says that she's too busy to explore it— she's not scared, just too busy to go in. ...or is she? Anyway, after she leaves, use Cut on one of the trees blocking your way north, and head straight north. Pick up the Ether and hidden Insect Plate, and enter the mansion.

Go into the room with the TV, save your game and prepare to fight a legendary Pokémon!

Catching Rotom

This article is incomplete. Please feel free to edit this article to add missing information and complete it. Reason: Rotom's moveset

Make sure that you save your game and check if you have at least 20 Dusk Balls before proceeding!

When you're ready, walk up to the TV and press A to initiate a battle with Rotom.

Rotom is an Electric/Ghost-type legendary Pokémon, at Level 15 (unbelievable for a legendary Pokémon). Its stats aren't the best, but it can be bred with Ditto in order to obtain an egg. Its Special Attack and Speed are pretty good, its Defense and Special Defense are OK, and its HP and Attack aren't very good.

Use a Ghost- or Dark-type move to lower Rotom's HP (don't try this if your Pokémon is strong), and then weaken it further, if necessary, with moves that aren't of the Dark, Ghost, Normal (False Swipe won't work), Fighting, or Ground type. When Rotom's HP bar is in the red zone, keep throwing Dusk Balls until you catch it.

If you accidentally knock Rotom out, just soft reset to make it reappear.
