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 vital spirit in battle.

The Pokémon is suffering from insomnia and cannot
fall asleep.

Insomnia

This Pokémon inflicts triple damage with critical hits, rather than the usual double damage.

If the Pokémon's attack lands a critical hit, the attack is powered up even further.

Sniper

Overworld: If the lead Pokémon has this ability, the wild encounter rate is increased.

Powers up Bug-type moves when the Pokémon's HP is low.
