but wait, what if mesprit is lurking?
There are certain factors that you need to look,
1.In the first page, it is written
- For each wandering Pokémon that is currently roaming the RNG will advanced by one upon game start. Wandering Pokémon are Mespirit, Cresselia, Moltres, Zapdos and Articuno.
Mesprit
Frame: 5
Testers: 1 (Wild Eep)
Actually the starting frame should be 5, but when it tested by "Wild Eep", it is 1 instead of 5.
So you may choose the starting frame, whether it is 1 or 5.(in my opinion, you better choose starting frame 1, because it has been tested by Wild Eep)
--------------------------------------------------------------------------------------
2.To make the wandering appear in the area you are in, you need to walk until it appear in your area, right??
Every step that you take also advances the frame. So before you start to catch wandering pokemon, I think it's better for you to understand this article first
RNG Advancement For Wild Pokémon
GRASS / WATER / CAVES (Where there are wild Pokémon)
- Straight walking advances the RNG by 1 seed per step. The RNG is advanced even if there is a repel in use.
- Each time you turn around (reverse direction) the RNG is advanced by 1 seed. The RNG is advanced even if there is a repel in use.
- Turning and walking (1 step) at the same time advances the RNG by 2 seeds. The RNG is advanced even if there is a repel in use.
- Sweet Scenting in the grass / caves advance the RNG by 7 seeds. This is includes the calls to generate the monster and the effects of the battle.
- Sweet Scenting in the water advance the RNG by 8 seeds. This is includes the calls to generate the monster and the effects of the battle.
- Random encounters advance the RNG by 1 seed, but a number of calls are made to create the Pokémon you will battle afterwards. The exact numbers for this and the following need further research.
- Battles makes a large number of RNG calls, but appear to unwind these calls after the battle to either seven or eight calls after the PID/IV generation of the Pokémon you battled.
EVERYWHERE
- 128 steps advance the RNG by a number of seeds equal to the number of Pokémon in your party.
- Wandering NPCs (Non-Player Characters) advance the RNG by 1 seed each time they move or turn. NPCs that move in a fixed pattern do not advance the RNG. All NPCs in a zone advance the RNG, even if they are not visible on the screen
- Opening the Journal, or having it automatically open, when there is a caught or defeated Pokémon on the first page advances the RNG by 2 seeds. There are a number of formats for the caught Pokémon text. Those listed below have been verified to advance the RNG.
'Caught a female BIDOOF.'
'Caught AZELF (LATE NIGHT).'
'UXIE was caught (DAY).'
'Defeated a male BIDOOF.'
- Flipping to the page in the journal where a caught or defeated Pokémon is listed advances the RNG by 2 seeds. The same message formats listed above will advance the RNG.
- Attempting to fish and getting the message 'Not even a nibble...' advances the RNG by 1 seed.
- Attempting to fish and getting the message 'The Pokémon got away...' advances the RNG as if a Pokémon had been encountered.
I might be wrong, because until now, I never tried to catch a wandering pokemon using RNG......
