Hustle

Trades accuracy for power.

Raises Attack by 50%; lowers the accuracy of physical-type moves, including status moves, by 20%.

Raises this Pokémon’s Attack by 50%. In Ruby and Sapphire, moves of physical types have their accuracy multiplied by 0.8 when they perform a random accuracy check, including status moves of those types. Special-type moves and one-hit KO moves are unaffected; moves that bypass the accuracy roll still bypass it.
