Stats, IVs, EVs and natures
Every Pokémon’s six stats (HP, Attack, Defense, Sp. Atk, Sp. Def and Speed) come from five things: its species’ base stats, its level, its IVs, its EVs and its nature. This page covers the last three, plus abilities, and the PBO items that let you change them.
Where to see them
Section titled “Where to see them”Click a Pokémon in your party (on the left of the screen) to open its card. It has five tabs down its right side: Summary, IVs, EVs, Moves and Skills.
The Summary tab shows the nature with the two stats it changes, for example +Atk and -SpA for Adamant. In the stat list, the number of the stat the nature raises is green and the one it lowers is red. Under the stats, the IVs and EVs bars show the totals (out of 186 and 510); click either to open its tab.
IVs: natural potential
Section titled “IVs: natural potential”IVs (individual values) range from 0 to 31 in each stat, so a perfect Pokémon has 186 in total. They come with the Pokémon when you catch it and do not grow through battles. Wild shiny Pokémon always have at least 15 in every IV.
PBO has three items that change IVs:
| Item | What it does |
|---|---|
 IV Randomizer |
Rolls a new set of all six IVs. You see both sets and choose which to keep. |
 IV Potion |
Adds 1 IV to one stat you choose, up to 31. Each Pokémon can take a limited number. |
 IV Toxin |
Removes 1 IV from one stat you choose, for when you want a low value (for example 0 Speed). |
The limits, the pity system for Randomizers and where to get each item are on IV items and the pity system.
EVs: training
Section titled “EVs: training”EVs (effort values) are training points. Your Pokémon earns them by defeating wild Pokémon: each species gives a fixed yield, such as 1 HP or 2 Speed.
The yields are listed on every Pokémon locations page. The EV training page lists the best places to earn each stat.
Allocated and unallocated EVs
Section titled “Allocated and unallocated EVs”PBO keeps two pools:
- Unallocated EVs have been earned but do not improve the stat yet.
- Allocated EVs are assigned to their stat and count towards it.
EVs earned for a stat stay tied to that stat: Speed EVs can only be allocated to Speed.
The first time you earn EVs, a short lesson asks how future EVs should work. Automatic allocation is on by default and allocates earned EVs straight away. With it off, they stay unallocated until you allocate them yourself; you can switch it later with Auto EV Assignment in Settings.
To allocate by hand:
- Open the EVs tab. Open the EVs tab of the Pokémon’s card. Each stat’s row shows its allocated EVs out of 252 and, on a tag, any unallocated EVs it has.
- Drag the bar. Drag the stat’s bar to the right. It only moves over that stat’s unallocated EVs.
- Apply. Press Apply, which shows how many EVs you are allocating. Cancel puts the bars back.
EV limits
Section titled “EV limits”| Limit | Value |
|---|---|
| Allocated EVs in one stat | 252 |
| Allocated EVs across all six stats | 510 |
| EVs one stat can hold, allocated and unallocated together | 252 |
| EVs a Pokémon can hold in total, allocated and unallocated | 756 |
Once a stat holds 252 EVs, further EVs for that stat are thrown away. Once the Pokémon holds 756 EVs in total, it stops earning EVs.
Changing EVs
Section titled “Changing EVs”Use these from your Bag and pick the Pokémon. Each stat has its own three items:
- A vitamin adds 10 unallocated EVs.
- A berry removes 10 unallocated EVs.
- A Super berry moves all allocated EVs of that stat back to unallocated, so you can spend them again.
| Stat | Vitamin (+10) | Berry (−10) | Super berry |
|---|---|---|---|
| HP |  HP Up |
 Pomeg Berry |
 Super Pomeg Berry |
| Attack |  Protein |
 Kelpsy Berry |
 Super Kelpsy Berry |
| Defense |  Iron |
 Qualot Berry |
 Super Qualot Berry |
| Sp. Atk |  Calcium |
 Hondew Berry |
 Super Hondew Berry |
| Sp. Def |  Zinc |
 Grepa Berry |
 Super Grepa Berry |
| Speed |  Carbos |
 Tamato Berry |
 Super Tamato Berry |
Two more items clear EVs from every stat at once:
Unallocated EV Reset removes every unallocated EV, keeping allocated ones.
Full EV Reset removes all EVs, allocated and unallocated.
Vitamins are not capped per stat in PBO; only the EV limits above apply.
Vitamins can also be used straight from the EVs tab: press the vitamin at the end of a stat’s row (it shows how many you have) and confirm.
Where to get them
Section titled “Where to get them”| Item | Where | Cost |
|---|---|---|
| Unallocated EV Reset | Casino Token Store, Veilstone Game Corner | 80 Casino Tokens |
| Full EV Reset | Casino Token Store, Veilstone Game Corner | 100 Casino Tokens |
| All six Super berries | Dynite Ore Shop | 15 Dynite Ore each |
| Vitamins and both resets | Vs. Seeker | Drop as rewards |
Natures
Section titled “Natures”A nature raises one stat and lowers another. Five natures (Bashful, Docile, Hardy, Quirky and Serious) change nothing. To pick one for a story team, see building a team.
A Pokémon’s nature is fixed when you catch it, and PBO has no item that changes it, so choose carefully.
| Nature | Raises | Lowers |
|---|---|---|
| Adamant | Attack | Sp. Atk |
| Bashful | — | — |
| Bold | Defense | Attack |
| Brave | Attack | Speed |
| Calm | Sp. Def | Attack |
| Careful | Sp. Def | Sp. Atk |
| Docile | — | — |
| Gentle | Sp. Def | Defense |
| Hardy | — | — |
| Hasty | Speed | Defense |
| Impish | Defense | Sp. Atk |
| Jolly | Speed | Sp. Atk |
| Lax | Defense | Sp. Def |
| Lonely | Attack | Defense |
| Mild | Sp. Atk | Defense |
| Modest | Sp. Atk | Attack |
| Naive | Speed | Sp. Def |
| Naughty | Attack | Sp. Def |
| Quiet | Sp. Atk | Speed |
| Quirky | — | — |
| Rash | Sp. Atk | Sp. Def |
| Relaxed | Defense | Speed |
| Sassy | Sp. Def | Speed |
| Serious | — | — |
| Timid | Speed | Attack |
Abilities
Section titled “Abilities”Every Pokémon has one ability. Most species have one or two regular abilities and a hidden ability; the in-game Pokédex lists all of them.
Two items change an ability:
| Item | What it does | Dynite Ore Shop price |
|---|---|---|
 Ability Capsule |
Swaps a Pokémon’s regular ability for its other regular ability. It does nothing for a Pokémon that has a hidden ability or only one regular ability. | 60 Dynite Ore |
 Ability Patch |
Changes a regular ability to the hidden ability. Used on a Pokémon that already has its hidden ability, it switches back to one of the regular abilities at random. | 125 Dynite Ore |
A Pokémon with Trace shows you a wild Pokémon’s ability in battle, which helps when you hunt for a specific ability.
