# Adding World Modifiers to Your Valheim Server

Learn how to add and change world modifiers for your Nodecraft Valheim dedicated server. 

This article will show you how to add and change world modifiers for your Valheim dedicated server. World modifiers allow you to customize different options to increase or decrease how challenging you want your server to be. There are several different modifiers, such as combat difficulty, resource gains, and raid frequency.

## World Modifier Options

### Presets

Presets are a good starting point for your server, as they’ll change several different `Modifiers` at once. You can further tune your server by setting individual modifiers (see next section of options).

Format: `-preset <value>`

Example: `-preset hard`

Values:

```
casual
easy
normal
hard
hardcore
immersive
hammer
```

### Modifiers

Modifiers are for when you want more control over how your server behaves. You can also use these to fine-tune a `preset` (see previous section).

Format: `-modifier <modifier> <value>`

Example: `-modifier combat easy`

Options:

| Modifier | Value |
| --- | --- |
| combat | veryeasy easy hard veryhard |
| deathpenalty | casual veryeasy easy hard hardcore |
| resources | muchless less more muchmore most |
| raids | none muchless less more muchmore |
| portals | casual hard veryhard |

### Keys (Toggles)

Keys or toggles are a way for you to configure your server further. These are basically on/off types of settings.

Format: `-setkey <value>`

Example: `-setkey passivemobs`

Values:

```
nobuildcost
playerevents
passivemobs
nomap
```

If you’d like to know further information about what each modifier does, we recommend checking out the [Valheim Wiki](https://valheim.fandom.com/wiki/World_Modifiers).

## Adding the World Modifiers to Your Server

### Startup Argument

You’ll add these world modifiers to your server as a Startup Argument for your server. Startup arguments need to be set before the server is turned on, so make sure your server is offline first.

Within the Nodecraft Pro panel, go to the `Game Settings` tab on the left-hand side, and then click the `Advanced Options` button.

New settings will appear in the panel, including the `Startup Arguments` text field.

**IMPORTANT:**** Make sure to include the dash (**`-`**) before each world modifier.**

Servers read startup arguments in order as written, therefore we recommend setting a `preset` first (if you want to use one), then the individual `modifier` settings after.   
Setting a `preset` will overwrite previously set `modifiers`.   
We’ll be showing an example and screenshot later on in this article, so don’t worry!

To add more than one world modifier, click on the plus (`+`) button on the right-hand side.

Here’s an example of us adding several different world modifiers to the Startup Argument field.

Make sure that the `preset` one is first, followed by the `modifier` and `setkey` options.

Be sure to press the `Save` button, and you’re all set to `Start` your server up and begin playing!
