# Fortifying

## :point\_right: Start Here

* Outposts **do not** need to be fortified to earn ADA rewards
* Outposts can be fortified using derp character NFTs
* Anyone can fortify any outpost, even if they do not own it
* The outposts' faction determines which character collection can be used to fortify it
* All characters fortifying an outpost earn Derp Dollars(DD) each epoch
* A fully fortified outpost earns Derp Dollars each epoch

**How much $derp?!**

More details about how much $derp is earned and how to claim [can be found here](/derp-birds/gold-rush-outposts/advanced/usdderp-rewards.md).

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://guide.derpbirds.io/derp-birds/gold-rush-outposts/outposts-overview/fortifying.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
