When the Pokémon has a status condition, its Speed stat is boosted by 50%. Being paralyzed does not lower the Pokémon's Speed stat.
Quick Feet (Japanese: はやあしQuick Feet) is an Ability introduced in Generation IV.
Effect
In battle
While a Pokémon with this Ability has a status condition, its Speed is increased by 50%. Additionally, a Pokémon with this Ability does not lose Speed due to paralysis.
Outside of battle
If a Pokémon with Quick Feet is in the first place in the party (even if fainted), the chance of encountering a wild Pokémon is decreased by 50%. It shares this effect with Stench, White Smoke and Infiltrator (since Generation VIII).
