Serene Grace (ability)

Serene Grace is an Ability introduced in Generation III.

In battle
Serene Grace  doubles the chance of moves' secondary effects occurring - specifically stat changes, status ailments, or flinching. It also increases the chance of flinching due to the held items King's Rock and Razor Fang from 10% to 20% (however, note that those items do not affect moves that already have a flinch chance).

Serene Grace  does not affect status moves or the Pokémon's critical hit ratio.

Outside of battle
Serene Grace has no effect outside of battle.
