There are plenty of Trainers out there that want to capture all 493 Pokémon in Pokémon Brilliant Diamond and Shining Pearl, and that’s what our guides are designed to do. We also often cover other game mechanics. Pokérus in Pokémon Brilliant Diamond and Shining Pearl is one of those very weird things about this game. First introduced in Pokémon Gold and Silver, Pokérus is a virus that the Pokémon in your party might contract. There are some very specific circumstances that allow it to transmit, and the chance o it happening in battle is pretty low.
The odds are so low, that it’s basically impossible to encounter it without trading for it— 3 in 65,536 to be exact. Most players will seek out a monster with the affliction owned by another Trainer, then have them engage in an online battle. This is one handy trick that helps with transmission. Also, Shiny Pokémon will have a much higher chance of transmitting the virus, so shiny hunters be on the lookout.
So why would you want Pokérus? It’s simple, as it offers a very unique bonus. There’s no noted downside for it, bu there is one big upside. The game allows any Pokérus-afflicted Pokémon to gain EVs at double the normal rate. This is very useful for EV training. Combine this with the VS Seeker to speed EV training up.
Pokérus in Pokémon Brilliant Diamond and Shining Pearl can technically be prolonged for an indefinite amount of time. You need to just place the infected monster into a storage box and leave it there. Once you take the afflicted Pokémon out of the box for a few days, the infection will cure itself. The one reason you might want to do this is to extend the window to get more EVs faster.
If you’re chasing more evolutions, there’s plenty more. Budew and Kadabra can both be evolved in similar ways for this game. but if you don’t want to waste time with that, there’s a duplication exploit floating around. Evolution items are a big part of the game now, in this modern era of Pokémon. There are tons of evolution stones and other items you need to hunt for, like the Reaper Cloth. There are both stat-boosting and evolution items you might want. The Splash Plate is useful for Water-favoring Trainers. You could also be hunting for the Electrizer, which is useful for getting Electabuzz.
