The core loop is a click. Each click on the grass may turn up a wild Pokémon; the rate depends on where you are and what your lead Pokémon can do. Some abilities change how often something appears, and some change what it is carrying.
Abilities that work outside battle↑
| Ability | What it does out in the field |
|---|---|
| Pickup | After any battle, a 10% chance to find something and put it straight in the bag. Only if the Pokémon is not already holding an item. |
| Honey Gather | A 5% chance of finding Honey after a battle. |
| Compound Eyes | Wild Pokémon are four times as likely to be holding an item (20% instead of 5%). |
| Super Luck | The same as Compound Eyes for held items. |
| Flame Body / Magma Armor / Steam Engine | Eggs need half the steps to hatch. |

The Pokédex and the Worlddex↑
Your own Pokédex records what you have seen and caught. The Worlddex is different: it is a single global registry of first catches, shared by every player. Only the first person to catch a given species and variant is recorded there, and the database enforces it — two simultaneous claims cannot both win.
