Legends: Arceus · Research, outbreaks & charm · Best odds 1/128
Legends: Arceus produced the friendliest shiny odds any mainline game has offered, and it did it without breeding, resets or chains: fill in the Pokedex, clear outbreaks, and the numbers come to you. A fully stacked mass outbreak tops out at 1 in 128. Everything below comes from the community datamine, laid out in the order Hisui actually stacks its rolls, with the calculator staying inside the region.
Locked to Legends: Arceus. Switch on what you have running — the species' research progress, the Shiny Charm, and the kind of outbreak you are standing in — and the card shows your odds per spawn plus a hunt length. A single spawn can belong to a mass outbreak or a massive one, never both, so pick whichever you are actually clearing.
Base rate 1 in 4,096. Research Lv. 10 adds one roll and perfecting the page adds two more; the Charm contributes three. Everything stacks on the same wild spawn, which is how Hisui reaches 1 in 128.
The chart is yours. If the research grind can wait, the generator hands out shiny-coloured Pokemon on demand — no outbreaks, no timers. Hunting another title? The hub covers them too.
Reference
Hisui runs on one long ladder rather than a menu of methods: research rolls, charm rolls and outbreak rolls all land on the same spawn. The chart below walks the combinations, from a bare 1 in 4,096 to the 32-roll mass outbreak that the series still has not beaten.
| Hunt | Shiny rolls | Shiny odds | Chance |
|---|---|---|---|
| Wild spawn (no boosts) | 1 | 1 in 4,096 | 0.0244% |
| Research Lv. 10 | 2 | 1 in 2,048 | 0.0488% |
| Research Lv. 10 + perfect page | 4 | 1 in 1,024 | 0.0977% |
| Research Lv. 10 + Charm | 5 | 1 in 819 | 0.1221% |
| Research Lv. 10 + perfect page + Charm | 7 | 1 in 585 | 0.1709% |
| Massive Mass Outbreak | 13 | 1 in 315 | 0.3174% |
| Massive Mass Outbreak + Lv. 10 | 14 | 1 in 293 | 0.3418% |
| Massive Mass Outbreak + perfect + Charm | 19 | 1 in 216 | 0.4639% |
| Mass Outbreak | 26 | 1 in 158 | 0.6348% |
| Mass Outbreak + Lv. 10 | 27 | 1 in 152 | 0.6592% |
| Mass Outbreak + perfect page + Charm | 32 | 1 in 128 | 0.7812% |
The Perfect bonus only exists on top of Lv. 10, and the Charm is unobtainable without Lv. 10 across the dex — the chart folds both facts in. Rows list the two outbreak types separately because a spawn can belong to one or the other, never both.
Mechanics
Hisui hands out shiny rolls from four places at once. Here is what each one costs, and how they combine.
Raising a species to Research Lv. 10 adds a shiny roll to its spawns; taking the page all the way to Perfect adds two more, for three research rolls over the base. Because the charm itself is only issued once every species sits at Lv. 10 or above, a charm-holding save is always carrying research rolls as well — which is why the "charm only" combinations on the chart start at 5 rolls and 1 in 819 rather than anything weaker.
Both kinds of outbreak pour rolls onto whatever appears inside them, but they bargain differently. A mass outbreak adds 25 rolls to a single species with no timer attached, and at full research plus the charm it runs 32 rolls — 1 in 128, the best figure in this page's chart. A massive mass outbreak adds 12 rolls but blankets whole regions with several species at once, so each individual spawn is less boosted while the number of encounters per minute jumps. Chase one target in mass outbreaks; farm many in massive ones.
There is no breeding in Hisui and nothing worth soft-resetting, which simplifies planning: every Pokemon is a wild spawn, and every wild bonus applies to it. You cannot Masuda your way to 1 in 512 here, but no hunt ever falls to bare full odds by accident either — with research finished and the charm in hand, even a random walk through the Crimson Mirelands sits at 7 rolls. Shinies appear in the overworld with a flash and a chime, so most finds are spotted long before anyone reaches for a ball.
Rarity
Every mythical and legendary encounter in Hisui is locked, along with the starter gift in its three forms, the Alolan Vulpix gift, Manaphy and Phione, and each forced battle in requests and missions. Soft-resetting the big names goes nowhere. The flip side is generous: starter species still shine in the wild — Space-Time Distortions are the dependable place to find them — and no other mainline game lets you hunt its box legends in the wild at full odds the way Hisui does with everything else.
In practice
The chart gives the rate; these rows give the wait. Every headline figure becomes a pair of counts — the halfway point, and the finish line that all but one hunter in a hundred will cross.
| Your shiny odds | Median hunt (50%) | 99% of hunters by |
|---|---|---|
| 1 in 4,096 (full odds) | 2,839 encounters | 18,861 encounters |
| 1 in 819 (Charm, research minimum) | 568 encounters | 3,773 encounters |
| 1 in 585 (perfect research + Charm) | 406 encounters | 2,695 encounters |
| 1 in 315 (massive mass outbreak) | 219 encounters | 1,451 encounters |
| 1 in 158 (mass outbreak) | 110 encounters | 726 encounters |
| 1 in 128 (perfect + Charm + mass outbreak) | 89 encounters | 590 encounters |
The last row is the friendliest shiny rate a mainline game has shipped: half of all hunters find theirs inside 89 spawns, and 99% inside 591. At spawn-dense outbreak sites those numbers collapse into minutes, not hours.
FAQ
A mass outbreak with perfect research and the Shiny Charm — 32 rolls against the 1 in 4,096 base, which works out to 1 in 128. Nothing else in Hisui, and nothing in any later mainline title, has beaten that rate.
The chart on this page lists each stacking combination the game allows: research at Lv. 10 or Perfect, with or without the Charm, inside mass or massive mass outbreaks. Two rules keep it simple — Perfect counts on top of Lv. 10, and a spawn belongs to one outbreak type at most.
Lv. 10 for a species adds one roll to its spawns, and perfecting the page adds two more, for three research rolls in total. They apply everywhere a spawn can happen, which makes them the only shiny bonus in the series that rides along on every hunt.
It is the other way round. A mass outbreak contributes 25 rolls and a massive one contributes 12, but massive outbreaks flood entire regions with several species at once. Use them to farm volume, and regular outbreaks to chase one particular shiny.
The copies you are given are locked, yes — but the species still shines in the wild: starter lines spawn inside Space-Time Distortions, and those spawns can come out shiny. Only the gift copies are off the table.
It contributes three rolls, the same as in Z-A, but there is a catch worth knowing: earning the charm requires Lv. 10 research everywhere, so a charm hunt always carries research rolls on top — 5 rolls minimum, 1 in 819, before outbreaks even enter the picture.
Moving sideways in time, the Pokemon Brilliant Diamond & Shining Pearl Shiny Odds page covers the Poke Radar chain that peaks at 1 in 99, the Pokemon Legends: Z-A Shiny Odds page shows what the newest Legends game built from this same outbreak idea, and Pokemon Scarlet and Violet Shiny Odds carries outbreaks into the sandwich era. The Pokemon Shiny Odds hub keeps every game's chart in one place.
