Sheer Force

Strengthens moves with extra effects to 1.3× their power, but prevents their extra effects.

Full effect

This Pokémon's moves with extra effects have 1.3× their power, but lose their extra effects. An effect chance is a move's chance to inflict a status ailment, cause a stat change, or make the target flinch in addition to the move's main effect. For example, Thunder Shock's paralysis is an extra effect, but Thunder Wave's is not, nor are Knock Off's item removal and Air Cutter's increased critical hit rate. Moves that lower the user's stats are unaffected.

In game description

Removes any additional effects from the Pokémon's moves, but increases the moves' power.

Using Sheer Force in Cobblemon

Abilities are passive and always active, so Sheer Force 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.
