Sap-Sipper

Sap-Sipper is an ability in the Pokémon series that offers significant strategic advantages in battle. When a Pokémon with the Sap-Sipper ability is hit by a Grass-type move, it nullifies the move's effects and instead boosts the user's Attack stat by one stage. This makes Sap-Sipper an excellent ability for Pokémon that want to deter opponents from using Grass-type moves and allows the holder to capitalize on potential Attack increases.

Effects

Immunity to Grass-type Moves: Sap-Sipper renders the Pokémon immune to all Grass-type moves, including those that typically inflict status conditions or have secondary effects.
Attack Boost: Each time a Pokémon with Sap-Sipper is targeted by a Grass-type move, its Attack stat rises by one stage, enhancing its physical offensive capabilities.

Key Points

Strategic Advantage: By granting immunity and a stat boost, Sap-Sipper can significantly alter the course of a battle. Opponents may avoid using Grass-type moves entirely,

Effects

Whenever a grass-type move hits this Pokémon, its Attack rises one stage, negating any other effect on it.
