Effect
Ups super effective moves. (Hold)
Expert Belt increases the power of super effective moves by 20%. Unlike Choice items, you're not locked into one move, and unlike Life Orb, you don't take recoil damage! The catcht here is you only get the boost on super effective hits.
This item works best on Pokémon with wide coverage that can hit a lot of types super effectively. It's also good for bluffing Choice items since you get similar damage output without the move lock. A solid middle-ground option if Life Orb recoil or Choice restrictions don't fit your playstyle.
