Struggling to catch Legendaries like Dialga or Shaymin in Pokémon Brilliant Diamond & Shining Pearl (BDSP)? A Pokémon catch rate calculator can help! Learn how it works, the best Poké Balls to use, and expert tricks to improve your success rate.
What is a Pokémon Catch Rate Calculator?
A Pokémon catching calculator estimates your odds of capturing a wild Pokémon based on:
- Species’ base catch rate (e.g., Legendaries = 3, Pikachu = 45).
- HP remaining (lower = better chance).
- Status conditions (sleep/freeze boost odds).
- Type of Poké Ball used (Ultra Ball, Quick Ball, etc.).
BDSP Catch Rate Formula (Simplified)
The game uses a modified version of the classic formula:Catch Chance=(3×Max HP−2×Current HP)×Catch Rate×Ball Modifier×Status Modifier3×Max HPCatch Chance=3×Max HP(3×Max HP−2×Current HP)×Catch Rate×Ball Modifier×Status Modifier
Example:
- Catching a sleeping Palkia at 1HP with an Ultra Ball:
- Base catch rate: 3
- Ultra Ball: 2x
- Sleep modifier: 2.5x
- Final odds ≈ ~15%
Best Poké Balls for Catching (BDSP)
| Ball | Best For | Catch Modifier |
|---|---|---|
| Quick Ball | First-turn catches | 5x (Turn 1 only) |
| Ultra Ball | General use | 2x |
| Dusk Ball | Caves/Nighttime | 3.5x |
| Timer Ball | Long battles | Up to 4x |
3 Pro Tips to Improve Catch Rate
