# Spawn Conditions

Spawn Conditions are a way for you to override the vanilla conditions system, and configure conditions of your own.

To add a mob to override, simply create a list for a mob under the `spawn-conditions` option in the entities section of the config.yml. You can find a list of entities that correspond to the version of your server by [clicking here](https://bg-software.com/entities/).

#### Examples

```yaml
# Setting an empty list to a mob will remove all spawn conditions
spawn-conditions:
  COW: []

# This example will remove all other spawn conditions and only have NOT_PEACEFUL as a spawn condition for Zombie.
spawn-conditions:
  ZOMBIE:
  - NOT_PEACEFUL
```

## Conditions

This is a list of spawn-conditions available by default.

{% hint style="info" %}
Note that not all these conditions exist, depending on your server version. Be sure to check Mob Group!
