Boosts the rate of added effects.
Serene Grace is an ability that doubles the chances of secondary effects occurring when the Pokémon uses a move. For example, if a move has a 10% chance to cause paralysis, with Serene Grace, that chance is increased to 20%. This ability can be particularly useful for moves that have beneficial secondary effects, such as causing status conditions or stat changes.
