At the end of each turn, Healer has a 30% chance of curing an adjacent ally's status condition. If the Pokémon has multiple adjacent allies with status conditions, it has an independent 30% chance of curing each one, and can cure more than one in the same turn. If it cures a status condition, it does so before burn or poison damage is dealt on that turn.
At the end of each turn, if it is raining, Hydration will cure the Pokémon of any non-volatile status condition. If it cures a status condition, it does so before burn or poison damage is dealt on that turn. Pokémon who are made drowsy by Yawn will not fall asleep until after Hydration takes effect, and as such, will not be healed until the end of the next turn.
When a Pokémon with Moxie directly causes another Pokémon (including allies) to faint by using a damaging move, its Attack is increased by one stage. If its Attack is already at +6 stages, Moxie will not activate.
Moxie activates after the Pokémon gains Attack from Fell Stinger. If a Pokémon with Moxie defeats a Pokémon with Mummy using a contact move, the Pokémon's Ability will become Mummy before Moxie has the opportunity to activate.
Snow Warning summons a hailstorm in battle as soon as a Pokémon with Snow Warning enters the battle. Its effects are the same as Hail, lasting for five turns. If a Pokémon with Snow Warning is sent out in the same turn as another Pokémon whose Ability affects the weather, the slower Pokémon's Ability will override the faster Ability.
