Abilities affecting encounters

[Pinsplash]

From Pokémon Emerald onward, if a Pokémon with Static is in the first place in the party (even if fainted), then there is a 50% chance the game will force an encounter with an Electric-type Pokémon, if one is possible.

From Pokémon Emerald onwards, if a Pokémon with Magnet Pull is in the first place in the party (even if fainted), then there is a 50% chance the game will force an encounter with a Steel-type Pokémon, if one is possible.

From Pokémon Emerald onwards, if a Pokémon with Hustle, Pressure, or Vital Spirit is in the first slot in the party (even if fainted), there's a 50% chance that a Pokémon will be forced to the upper bound of their encounter level range. In gen 5, this ability does not apply to fishing encounters. In emerald and gen 4, it does. We need to investigate gen 6 and 7 as bulbapedia does not know.

From Pokémon Emerald onwards, if a Pokémon with Intimidate or Keen Eye is in the first place in the party (even if fainted), there is a 50% chance it will prevent a random wild encounter that would have occurred if the wild Pokémon would be at least 5 levels lower than the Pokémon with Intimidate or Keen Eye.

best to keep the level used for this separate from repellevel. these two levels are not the same in all situations.

H/P/VS: per-slot or per-table?

emerald: per-slot (code), and if the ability does NOT activate, the pokemon's level is reduced by 1 if it was going to be more than the minimum level.
DP: land is per-table, water methods are per-slot (data)
platinum: land is per-table, water methods are per-slot (data, code)

Static and Magnet Pull: weight method?

imagine Magnet Pull activates in a table that had a 20% Bronzor slot and two 1% Magnemite slots.

• weighing slots equally means the odds would become 33% Bronzor and 66% Magnemite.
• weighing mons equally means the odds would become 50/50.
• original odds means they stay as 20% Bronzor and 2% Magnemite.

Static and Magnet Pull: which encounter methods are affected?

There are no Steel types found in water. Presuming Magnet Pull works on land as it would be pointless otherwise. This question is only for Static.

emerald: on land and surfing (code)
DP: Fishing data, presuming it works on land and surfing as well because that would be very weird if it did not.
platinum: all (code)
