Lingering Aroma

When a Pokémon with this Ability is hit by a move that makes contact, the attacking Pokémon's ability will be changed to Lingering Aroma. If a Pokémon affected by Lingering Aroma is switched out, it regains its original Ability.

If a Pokémon with this Ability is hit by a multi-strike move that makes contact (such as Fury Swipes), the attacking Pokémon's Ability will become Lingering Aroma after the first strike.

If a Pokémon with Rock Head uses a recoil contact move on a Pokémon with Lingering Aroma, its Ability will become Lingering Aroma, then subsequently it will take recoil damage.

Multitype, Zen Mode, Stance Change, Schooling, Battle Bond, Power Construct, Shields Down, RKS System, Disguise, Comatose, Zero to Hero, Mummy and Lingering Aroma itself are not affected by Lingering Aroma. Lingering Aroma on Bulbapedia
