Horn Leech is a Grass-type move with 75 power and 100% accuracy. It drains the target's health, healing the user for 50% of the damage dealt. This makes it particularly useful for sustaining the user during battles. Introduced in Generation V, Horn Leech is commonly associated with Pokémon like Sawsbuck and Tapu Bulu. Its healing effect combined with decent power makes it a strategic choice for Grass-type Pokémon looking for longevity on the battlefield.
