The Level Ball (Japanese: レベルボールLevel Ball) is a type of Poké Ball introduced in Generation II. It can be used to catch a wild Pokémon, being more likely to succeed the higher the Trainer's Pokémon's level is than the wild Pokémon's.
When used from the Bag in a wild encounter, it attempts to catch the wild Pokémon with the following catch rate modifiers:
1× if the player's Pokémon is less than or equal to the level of the wild Pokémon
2× if the player's Pokémon is at a higher level, but less than double, the level of the wild Pokémon
4× if the player's Pokémon is more than double, but less than four times, the level of the wild Pokémon
8× if the player's Pokémon is at a level at least four times that of the wild Pokémon
If used on an Ultra Beast, the catch rate modifier is instead always set to 0.1×.
The Level Ball cannot be used in situations in which Poké Balls cannot be used, such as in wild battles with two or more opponents currently present or against a trial Pokémon. If used in a Trainer battle, the opposing Trainer will bat the ball away, wasting the item.
The Level Ball, first found in Next Destinies, allows them to do the same with a Pokémon that has 90 HP or less. search through their deck for a Pokémon that has 90 HP or less and put it in their hand.
