Have you ever wanted to lower your Pokemon's level? Have you ever looked at your team and thought: "What if my Dragonite was level 3?" Probably not. But now you can.
Exp Candy M + Pomeg Berry + Dried Kelp + Sugar
Use it to lower your Pokémon level
Clearly it doesn't drop you below 1.
You can find it right beside the Rare Candy, under "Consumables".
Obvious, but useful.
