Muscle Bandin Pokémon Polished Crystal

Boosts physical moves by 10%. (Hold) Muscle Band provides a 10% boost to all physical moves, regardless of type. It's less powerful than type-specific items or Choice Band, but it works on all your physical attacks. This is a decent option for physical attackers with diverse movepools who want a small boost across everything rather than a big boost on one type. The 10% is modest buut pretty consistent.
