You will come across a number of contracts and side quests as you explore Horizon Forbidden West. One notable gig you’ll come across while visiting the Stillsands is for a Pristine Bellowback. You’ll meet Runda, who can give you this contract, and you’ll want to make sure you’re paying attention to what you need to do. In this guide, we cover how to complete a Pristine Bellowback contract in Horizon Forbidden West.
After accepting the quest, you’ll need to visit the Bellowback region just north of Runda and her camp. You can find it on your map while on the quest.
When you reach this location, you will find that you will be faced with Acid Bellowback. Your goal to complete this contract is to defeat this Bellowback without destroying the large Sac on its back or around its neck. This means avoiding these two areas for the entire war. If they are destroyed, you will not be able to harvest these ingredients, and therefore you will have to find another Bellowback or start the quest again.
These machines are very weak against Purgewater’s arrows. We highly recommend using these two to make the fight against it much easier and ensure you can beat it quickly. You will want to avoid using any harmful Acids on it. After defeating Bellowback, you can return to Runda to complete the contract.
