King's Rock gives attacking moves a 10% chance to flinch your opponent. Sheer Force removes the additional benefits of a move to increase the damage. I have a Sheer Force Nidoking that knows Megahorn and Sucker Punch. If it is true that a King's Rock adds a flinch chance on moves like these, will the increased damage apply from Sheer Force? Essentially, Sheer Force benefits for moves that would not ordinarilly apply, such as Aqua Tail, X- Scissor, or Feint Attack, while holding a King's Rock.
