The status effect that was set
Optionalpassive(For callers of applyAbAttrs): If provided, only apply ability attributes of the passive (true) or active (false).
This should almost always be left undefined, as otherwise it will only apply attributes of either the pokemon's passive (true) or non-passive (false) ability. In almost all cases, you want to apply attributes that are from either.
(For implementations of AbAttr): This will never be undefined, and will be true if the ability being applied
is the pokemon's passive, and false otherwise.
ReadonlypokemonThe pokemon that has the ability being applied
Optional ReadonlysimulatedWhether the ability's effects are being simulated (for instance, during AI damage calculations).
OptionalsourceThe pokemon that set the status condition, or undefined if not set by a pokemon
