# Mutations

{% hint style="info" %}
Please see the Helpful Commands page for information about commands relating to mutations!
{% endhint %}

### Souls

Souls are the currency of mutations. You can get a pokemon soul **only** from sacrificing the pokemon of that species. For example, you can sacrifice a riolu to get a riolu soul. You can also trade souls with players using the `/mutations gift` command.

### Mutating

You mutate a pokemon by using the `/mutations` command and selecting which mutation you wish to apply to a pokemon. You then select a valid party member to apply this skin to. For example, if you had 30 riolu souls, you could spend them on turning a riolu in your party into a costume skin.

See the Custom Pokémon page for mutations to see which skins you can get and how much they cost!
