# Spawners

As you open /crates and travel throughout the world, you will encounter spawners. Not just any normal spawners! If you get enough of one, you can stack them up to an amount of 5.

```yaml
  # The maximum number of spawners that can be in a single stack
  max-stack-size: 5
```

You may also shift + right click on a spawner to get details on when mobs will spawn.
