Level Ball

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

In Pokémon Gold, Silver, and Crystal, due to what is seemingly a coding mistake the wild Pokémon's remaining HP and status are ignored when calculating the catch rate; only the wild Pokémon's level is used for calculation if using a Level Ball.

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.

Fling fails if the user is holding a Level Ball.

In Pokémon HeartGold and SoulSilver only, Level Balls cannot be held. This is to prevent them being held by a Pokémon traded to Pokémon Diamond, Pearl, and Platinum, where the item does not exist.

In Teddiursa's Picnic, a Level Ball appeared in a fantasy during Maizie's explanation about Apricorn Poké Balls.

In Slugging It Out with Slugma, Crystal caught a group of Slugma in Level Balls. They reappeared in a flashback in The Final Battle IV.

In Off Course with Corsola, some of the Pokémon that Crystal had caught for Professor Oak were seen in Level Balls.

In Absolutely Azumarill, several Level Balls were seen in a basket full of Apricorn Poké Balls that Mirei delivered to Crystal.

In It Takes Xatu to Tango, Crystal threw a Level Ball at Arceus in order to estimate its strength. As the Ball had no effect on the Alpha Pokémon, she decided to use a Heavy Ball instead.

In For Pikachu's Sake!! The Search For The Missing Farfetch'd, Gold received a Level Ball from Kurt as thanks for helping to save the Slowpoke in the Slowpoke Well from drowning. In Let's Fight For The Future!!, he used it to capture and stop the rampage of the Black Tyranitar. The Ball containing the Black Tyranitar was then sealed underneath a statue in Cianwood City.
