What is Pokémon BDSP Catch Rate?
The Pokémon BDSP catch rate calculator helps trainers in Brilliant Diamond and Shining Pearl understand and predict their chances of successfully capturing a wild Pokémon. In the Sinnoh region, like in previous games, Pokémon have a hidden "catch rate" value that determines their base difficulty to catch. However, this base rate is heavily influenced by several in-game factors, including the Pokémon's level, its current HP, its status conditions, and the type of Poké Ball used. This calculator aims to demystify these complex interactions, providing a clear probability for trainers aiming to complete their Pokédex or find specific Pokémon.
Anyone playing through Pokémon Brilliant Diamond and Shining Pearl who engages in battles with wild Pokémon can benefit from understanding catch rates. Whether you're a casual player looking to catch a rare Pokémon, a competitive trainer needing a specific Pokémon with good stats, or a completionist aiming for the National Pokédex, knowing how to maximize your catch chances is crucial. Misunderstandings often arise regarding how each multiplier stacks and which conditions offer the biggest boost, leading to wasted Poké Balls or frustration when difficult Pokémon escape.
Pokémon BDSP Catch Rate Formula and Explanation
The catch mechanics in Pokémon Brilliant Diamond and Shining Pearl (BDSP) are based on a formula that calculates a catch "shake" probability, which ultimately determines if a Pokémon is caught. While the exact internal calculations can be complex, a simplified and practical approach involves calculating an overall modifier (A), then a final modifier (B) that incorporates the Pokémon's remaining HP, and finally, determining the actual catch probability for different ball types.
Simplified Catch Rate Calculation
The core of the calculation can be broken down into these steps:
- Calculate Modifier A: This is the product of various multipliers from status conditions, ball types (excluding Timer/Luxury/Repeat balls' specific logic), level balls, special attacks, and encounter types.
- Calculate Modifier B: This incorporates Modifier A and the Pokémon's current HP relative to its maximum HP. The formula is approximately B = A * (3 * Max HP – 2 * Current HP) / (3 * Max HP).
- Determine Catch Probability: This final probability is then compared against a random number. If the number is below the calculated probability, the Pokémon is caught.
Core Formula Components
The formula can be conceptually represented as:
Catch Rate % = (Modifier B / 255) * Ball Multiplier * 100%
Where:
- Modifier B is the result of applying HP and other conditions to an initial modifier (A).
- 255 is the maximum possible value for the internal catch check.
- Ball Multiplier varies greatly depending on the specific Poké Ball used and sometimes the game's state (e.g., Timer Balls get stronger over turns, Repeat Balls are better for owned Pokémon). This calculator uses simplified, common multipliers.

Practical Examples
Let's illustrate with a couple of scenarios in Pokémon Brilliant Diamond and Shining Pearl:
Example 1: Catching a Gible
- Pokémon: Gible
- Level: 25
- Base Catch Rate: 45
- Current HP: 1
- Max HP: 75
- Status Condition: None (Multiplier: 1.0)
- Ball Type: Ultra Ball (Multiplier: 2.0)
- Level Ball: No (Multiplier: 1.0)
- Special Attacks: Yes (False Swipe used) (Multiplier: 1.2)
- Assist Encounter: No (Multiplier: 1.0)
- Great Marsh/Safari Ball: No (Multiplier: 1.0)
Calculation Steps:
- Modifier A = (Status: 1.0) * (Level Ball: 1.0) * (Special Attacks: 1.2) * (Assist: 1.0) * (Marsh/Safari: 1.0) = 1.2
- Modifier B = A * (3 * Max HP – 2 * Current HP) / (3 * Max HP) = 1.2 * (3 * 75 – 2 * 1) / (3 * 75) = 1.2 * (225 – 2) / 225 = 1.2 * (223 / 225) ≈ 1.1893
- Final Catch Rate = Modifier B * Base Catch Rate = 1.1893 * 45 ≈ 53.52
- Catch Rate (%) (Ultra Ball) = (Final Catch Rate / 255) * Ultra Ball Multiplier * 100% = (53.52 / 255) * 2.0 * 100% ≈ 42.0%
Result: You have approximately a 42.0% chance to catch the Level 25 Gible with these conditions using an Ultra Ball.
Example 2: Catching a Staraptor with Status
- Pokémon: Staraptor
- Level: 30
- Base Catch Rate: 45
- Current HP: 1
- Max HP: 105
- Status Condition: Paralysis (Multiplier: 1.5)
- Ball Type: Great Ball (Multiplier: 1.5)
- Level Ball: Yes (Wild Pokémon level <= Player lead level) (Multiplier: 2.0)
- Special Attacks: No (Multiplier: 1.0)
- Assist Encounter: No (Multiplier: 1.0)
- Great Marsh/Safari Ball: No (Multiplier: 1.0)
Calculation Steps:
- Modifier A = (Status: 1.5) * (Level Ball: 2.0) * (Special Attacks: 1.0) * (Assist: 1.0) * (Marsh/Safari: 1.0) = 3.0
- Modifier B = A * (3 * Max HP – 2 * Current HP) / (3 * Max HP) = 3.0 * (3 * 105 – 2 * 1) / (3 * 105) = 3.0 * (315 – 2) / 315 = 3.0 * (313 / 315) ≈ 2.9809
- Final Catch Rate = Modifier B * Base Catch Rate = 2.9809 * 45 ≈ 134.14
- Catch Rate (%) (Great Ball) = (Final Catch Rate / 255) * Great Ball Multiplier * 100% = (134.14 / 255) * 1.5 * 100% ≈ 79.0%
Result: With Paralysis and using a Great Ball on a Staraptor whose level is not higher than your lead Pokémon, you have a significantly improved chance of roughly 79.0% to catch it.

Key Factors That Affect Pokémon Catch Rate in BDSP
- Base Catch Rate: This is fundamental. Pokémon like Magikarp have a very high base catch rate (255), making them easy to catch, while legendary Pokémon or rare species often have much lower base rates (e.g., 3).
- Current HP: The lower the Pokémon's current HP, the higher the catch rate. Bringing a Pokémon down to 1 HP, especially with moves like False Swipe, significantly increases your chances.
- Status Conditions: Inflicting Sleep or Freeze provides the largest multiplier (usually 2.0x), followed by Paralysis, Poison, or Burn (usually 1.5x). These are crucial for catching tougher Pokémon.
- Poké Ball Type: Different balls offer different base multipliers. Ultra Balls (2.0x) are generally better than Great Balls (1.5x), which are better than standard Poké Balls (1.0x). Specialized balls like Net Balls (Bug/Water) or Dive Balls (Water) offer higher rates in specific situations (simplified to 3.0x here). Master Balls have a 5.0x multiplier, guaranteeing a catch.
- Level Ball Bonus: If the wild Pokémon's level is the same or lower than your lead Pokémon's level, a Level Ball provides a significant boost (simplified to 2.0x here). This is invaluable for targeted shiny hunting or team building.
- Special Attacks & Abilities: Moves like False Swipe guarantee the target remains at 1 HP, maximizing the HP-related catch modifier. Abilities that don't knock out the opponent are key. This calculator simplifies this to a general multiplier.
- Encounter Type: In BDSP, specific encounters like the Great Marsh, Safari Zone, or Pokémon encountered via the Assist feature may have unique modifiers applied, as simplified in this calculator.
FAQ about Pokémon BDSP Catch Rate
- Q: What is the formula for catch rate in BDSP?
A: The exact formula is complex, but it involves a base catch rate, modifiers for status conditions, HP, ball type, and other factors. This calculator uses a simplified, practical representation. - Q: How does HP affect catch rate?
A: Lower HP increases catch rate. Bringing a Pokémon to 1 HP with False Swipe is a common strategy to maximize this effect. - Q: Which status condition gives the best catch rate boost?
A: Sleep and Freeze typically offer the highest multiplier (2.0x), making them the most beneficial status effects for catching. - Q: Are Ultra Balls always the best?
A: For general use, Ultra Balls (2.0x) offer a strong multiplier. However, specialized balls like Net Balls or Dive Balls can be better in specific situations (Bug/Water types or underwater encounters, respectively). Timer Balls become very effective after many turns. Master Balls guarantee a catch. - Q: Does the Level Ball work on any Pokémon?
A: The Level Ball bonus applies when the wild Pokémon's level is the same as or lower than your lead Pokémon's level. Its effectiveness varies based on the level difference. - Q: What does the "Assist Encounter" option mean?
A: In BDSP, some Pokémon can call for help, triggering an "Assist Encounter." These encounters often have a modified catch rate, which this calculator accounts for with a multiplier. - Q: How do I find a Pokémon's Base Catch Rate?
A: Base Catch Rates are fixed values for each species. You can find them in online Pokédex databases or guides for Pokémon BDSP. - Q: Can I use this calculator for Pokémon Legends: Arceus or Scarlet/Violet?
A: No, this calculator is specifically designed for the mechanics of Pokémon Brilliant Diamond and Shining Pearl. Catch mechanics vary significantly between different Pokémon games.
