Gym

For sidemods that allow player-owned Gyms to be registered, see Another Gym Plugin and Gym Wars 2: Feebas Unleashed.

A Gym is a structure that appears in its own themed village. Gyms have an assortment of NPC Trainers inside of them, each specializing in a certain type that the Gym corresponds to. At the end of each Gym is a Gym Leader, an NPC Trainer who is more difficult to defeat than the other NPC Trainers (aside from the 2 Boss trainers).

Like other structures, Gyms can be spawned with the use of Structure Blocks. The ID for each gym can be found further down the page in the "Gym Types" section. The rest of the village structures for the corresponding gyms have to be summoned separately.

Levels

The NPC Trainers inside a Gym are typically set to be "Equal" level, including the Gym Leader, and will use Pokémon that are the same level as the highest-level Pokémon in the player's party. Gyms will also include 2 Boss trainers, one "Epic" and one "Legendary," which will be 30 and 40 levels higher respectively.

Rewards

After defeating a Gym Leader, the Gym Leader will give a random Badge corresponding to the Gym's type.

Trivia

Back in 1.12.2, the "spawnGyms" config could toggle whether or not Gyms would spawn naturally.
