Vital Spirit

Prevents sleep.

Full effect

This Pokémon cannot be asleep. This causes Rest to fail altogether. If a Pokémon is asleep and acquires this ability, it will immediately wake up; this includes when regaining a lost ability upon leaving battle. This ability functions identically to Insomnia in battle. Overworld: If the lead Pokémon has this ability, higher-levelled Pokémon have their encounter rate increased.

In game description

The Pokémon is full of vitality, and that prevents it from falling asleep.

Using Vital Spirit in Cobblemon

Abilities are passive and always active, so Vital Spirit costs you nothing to run. If it is marked hidden on a species above, expect it to be harder to obtain: servers differ in whether hidden abilities come from breeding, an Ability Patch, or events.

See the Pokedex for which abilities each species can have, and IVs, EVs and breeding for how to actually pass one down.
