Sheer Force (Ability)

Sheer Force  increases the power of moves that have beneficial secondary effects by 30%, but removes those additional effects.

Beneficial  effects are defined as those that are positive for the user, such as:

Causing a status condition on the opponent (e.g. Thunderbolt)

Reducing the opponent's stats (e.g. Crunch)

Increasing the user's stats (e.g. AncientPower)

Non-beneficial effects, that  Sheer Force  will not activate for, include:

Recoil damage (e.g. Double-Edge)

Lowering the user's stats (e.g. Superpower)

If the user is holding a Life Orb and uses an attack that activates  Sheer Force, it will not receive the 10% damage from Life Orb, but it gets boosts from both Life Orb and  Sheer Force  (total of 69% base power increase).

Example

Flamethrower normally has a 10% chance to burn the opponent. With  Sheer Force, Flamethrower's base power is boosted from 95 to 124, but it will never cause a burn.
