Brilliant Diamond & Shining Pearl · Radar chains & eggs · Best odds 1/99
Pokemon Brilliant Diamond & Shining Pearl Shiny Odds
Brilliant Diamond and Shining Pearl are remakes of two games that shipped without a Shiny Charm — and they kept the quirk. The charm works for eggs and almost nothing else, while the real hunting tool is the returning Poke Radar, whose chain table climbs from 1 in 4,096 to 1 in 99 per shiny patch. The tables here follow the community's datamine, and the calculator is fixed to Sinnoh's four hunt types.

Pokemon Brilliant Diamond and Shining Pearl Shiny Odds
BDSP's remake math splits into three piles. Wild encounters, static encounters and radar patches roll at 1 in 4,096 with no charm help at all. Eggs run the modern Masuda ladder. And the radar keeps its own table, rewarding a disciplined chain with per-patch rates nobody expected from a DS remake.
| Hunt | Shiny rolls | Shiny odds | Chance |
|---|
| Wild encounter (the Charm has no effect) | 1 | 1 in 4,096 | 0.0244% |
| Grand Underground encounter | 1 | 1 in 4,096 | 0.0244% |
| Grand Underground + Diglett bonus | 2 | 1 in 2,048 | 0.0488% |
| Static encounter (legendaries included) | 1 | 1 in 4,096 | 0.0244% |
| Egg (no boosts) | 1 | 1 in 4,096 | 0.0244% |
| Egg + Shiny Charm | 2 | 1 in 2,048 | 0.0488% |
| Egg + Masuda Method | 6 | 1 in 683 | 0.1465% |
| Egg + Masuda + Charm | 8 | 1 in 512 | 0.1953% |
Static encounters — the ones you press A on, box legends and mythicals included — always sit at 1 in 4,096, charm or no charm. The upside: almost everything in Sinnoh can shine, and only two Pokemon in the whole game cannot.

The per-patch rate at each chain length, straight from the datamine. The curve near the top is why radar hunters treat a broken chain as a small disaster: dropping out at 36 costs you odds that take a long, careful rebuild.
Mechanics
How Shiny Odds Move in BDSP
Three routes matter in Sinnoh: the radar, the egg day-care and the static hunts. Each behaves differently from the modern games.
Poke Radar: the chain is the whole game
The radar works much as it did on the DS: trigger it in tall grass, then step into one of the shaking patches — up to four appear per use, and the safest pick is the one furthest from your character, away from the others. Every successful encounter grows the chain, and chain length sets the per-patch odds. The curve explodes near the top: chain 20 sits at 1 in 1,820, chain 36 cracks a thousand, and chain 40 reaches 1 in 99. Walking 50 steps without entering grass re-rolls the patches while keeping the chain, which is how hunters farm a finished chain instead of risking it. One ghost in the code is worth a mention: the game even computes a charm-adjusted radar rate, and never uses it.
The Shiny Charm that mostly does not work
BDSP inherited Diamond and Pearl's missing charm — the item exists, but it is wired into eggs and nothing else. In the grass, in caves, on statics, down in the Grand Underground and on radar patches, the charm changes nothing at all, which means a full-odds hunt here is exactly as slow as it was in 2006. Eggs are the one place it works, and they behave like Sword and Shield's: Masuda breeding rolls six times for 1 in 683, and eight with the charm for 1 in 512.
Static hunts stay generous
Where BDSP gives back is rarity. The only shiny locks in the entire game are the gift Mew and Jirachi handed out in Floaroma Town, so every other set-piece can be hunted the old way: save in front, start the battle, reset if the sparkle never comes. Dialga, Palkia, Giratina, the lake guardians, Heatran and the Ramanas Park lineup all work this way, and the event mythicals — Darkrai, Shaymin and Arceus — join them when their items are in hand.
Rarity
Shiny-Locked Pokemon in Brilliant Diamond and Shining Pearl
A short list: the gift Mew and Jirachi handed out in Floaroma Town for save data from other games, and the Pokemon that arrive through Mystery Gift. Those aside, there is no lock anywhere — not on the box legendaries, not on Ramanas Park, not on the event mythicals. Read alongside the charm's absence, that trade looks almost deliberate: almost nothing is blocked, but almost nothing is sped up either.
In practice
How Long Does a Sinnoh Hunt Take?
Radar odds are per patch rather than per wandering encounter, so raw counts understate how quickly a chained hunt moves. These rows still give the standard reading — median hunt and the 99% mark — for each headline rate.
| Your shiny odds | Median hunt (50%) | 99% of hunters by |
|---|
| 1 in 4,096 (wild, static or chain 0) | 2,839 encounters | 18,861 encounters |
| 1 in 993 (radar chain 36) | 688 encounters | 4,571 encounters |
| 1 in 400 (radar chain 38) | 277 encounters | 1,840 encounters |
| 1 in 99 (radar chain 40) | 69 encounters | 454 encounters |
| 1 in 512 (Masuda egg + Charm) | 355 encounters | 2,358 encounters |
A practiced radar hunter checks a batch of patches every few seconds after a 50-step reset, so a chain-40 session can outpace a plain grass hunt even where the fractions look similar. The calculator above runs the same maths on your own pace.
FAQ
Pokemon Brilliant Diamond & Shining Pearl Shiny Odds FAQ
What are the shiny odds in Brilliant Diamond and Shining Pearl?
Wild grass and static encounters sit at 1 in 4,096, and the Shiny Charm changes neither. The headline number is the Poke Radar: hold a chain to 40 and each shiny patch carries a 1 in 99 chance — the best radar odds the series has shipped.
How does the Poke Radar chain work?
The loop is simple: fire the radar, then walk into a shaking patch — you get up to four patches on each use. Every successful encounter grows the chain, and the per-patch rate climbs with it; one wrong encounter and you are back at zero. Staying out of the grass for a stretch — fifty steps or so — re-rolls the patches while the chain survives, which is the standard way to farm a finished chain.
Does the Shiny Charm work in BDSP?
Only for eggs, which is the remake's strangest detail. The item exists, and a radar calculation for it is even sitting in the game's code — it is simply never read. Wild encounters, underground hunts and radar patches all roll at their charm-free rates.
Can you shiny hunt the legendaries in BDSP?
Most of them, yes, and the method is the classic one: save in front of the encounter, start the battle, reset if it is not shiny. Dialga, Palkia, Giratina, the lake guardians and the Ramanas Park lineup all work this way — the only locked Pokemon in the game are the gift Mew and Jirachi, Mystery Gifts aside.
What are the egg shiny odds in BDSP?
The same ladder as Sword and Shield: 1 in 4,096 for a plain egg, 1 in 2,048 with only the Charm, 1 in 683 with the Masuda Method, and 1 in 512 with Masuda plus the Charm. Eggs are the one place BDSP's charm actually works, so leave the radar at home if you are breeding.
Is there a Diglett bonus for shiny odds in BDSP?
There is. The Diglett and Dugtrio scattered around the Grand Underground leave behind energy, and collecting 40 points triggers a four-minute bonus: encounters down there double up to 1 in 2,048 while it runs. The Shiny Charm does not stack with it — the bonus simply takes over the roll count.
