The perfect Pokemon is such a grind. Frankly, it was such a deterrent for a lot of dedicated players to expand just that bit of extra content into the main games just for perfect EVs and IVs. Hyper Training was a mechanic added in later games that sped up the process of earning IVs for your mons. This mechanism, first introduced in Sun and Moon, made its way into Sparkling Diamond and Sparkling Pearl. Here's what Hyper Training is and how to do it in Pokemon BDSP.
What is hypertraining?
The act of Hyper Training is when you bring a particular Pokemon's IV stat to its maximum potential. This gives players more ways to give their Pokemon the right stats than just spawning multiple times. However, if you want to pass egg moves and hidden abilities, you will still need to do so, although they have alternate processes as well.
To find out if your Pokemon has good IVs, you can do this by checking their stats with the Judge function on your PC. You earn this feature at the Battle Tower after talking to an NPC on the right side of the facility. If their rating for a certain stat is "Best!" then they don't need to hyper-train for that particular stat.
How to Start Hyper Training in Pokemon BDSP
Hyper Training wasn't in the original Diamond and Pearl in 2022, but has since made its way into the endgame. You'll need to beat the Elite Four first so you can fight your way to the battle zone. You can access it by talking to the ferryman in Snowpoint City. Next, head to the battle tower.
There are a trainer between Battle Point (BP) vendors who will take your Pokemon to hyper train them. You will have to win Bottle caps and trade them to the Hyper Trainer by the Battle Tower vendors. There are two types of bottle caps — Normal bottle caps and golden bottle caps.
If you give him a normal cap, he will train Hyper a specific stat have maximum IV for a Pokémon. If you give it a Golden, it will cause all stats for a Pokemon. Normal caps can be obtained via BP from the vendor on the left. Bonnets d’or can only be obtained through Battle Tower Master Class win streaks.
One important thing to note is that you can only Hyper Train Pokemon that have reached level 100 in Sparkling Diamond and Sparkling Pearl (BDSP).
Pokemon Shiny Diamond and Shiny Pearl are now available exclusively for the Nintendo Switch.
