This page offers a guide on how to complete the fifth phase of Rebuilding Dorrick in Colony 30 in Xenoblade Chronicles 3.

How to Start the Fifth Phase of Rebuilding Dorrick¶

In order to access the fifth phase of rebuilding Dorrick, you’ll need to have completed the other four phases of Rebuilding Dorrick, as well as have completed The True Culprit? quest which follows the fourth phase. After completing The True Culprit? you’ll be able to speak to Repapa and do your usual material collecting to fill up the progress bar.

Time to get collecting again - Repapa needs more materials!

How to Complete the Fifth Phase of Rebuilding Dorrick¶

This time a lot of the items can be found in later game areas such as the Cadensia Region. Some items are still collected in the early game areas too though! Below, you’ll find a potential strategy for completing this quest quickly, as well as a full list of all builds and where to find the required collectibles! Remember: you don’t actually need to make

The easiest way to get useful items is to use the fabricators at Ferronis Hulks. And one of the most useful Hulk fabricators for this phase is the Atoll Hulk in Erythia Sea and the Clifftop Fabricator on the Urayan Trail.

The Ocean Gear build is a really easy one because you can obtain Android Gear from the Clifftop Fabricator (1500G per fabrication) and then the Ocean Polyps can be obtained from the Atoll Hulk (1400G per fabrication)! If you used the Clifftop Fabricator to get items for Phase 4 you may already have a ton of Android Gears. Even though this build only gives 15% progress completion, we actually had so many Android Gears and Ocean Polyps that we were able to almost complete the entire phase with just makig Ocean Gear!

Prop-Palm Screw is also a good one to go for because Prop Branch can be purchased from Colony Mu, Ten-Term Palm are an easy resource to obtain from the Atoll Hulk and Warrior Screws are found in Conqueror’s Peak not far from Colony 30 in the Fornis Region. It’s worth 20% completion so going on a bit of a spending spree and then a quick trip to Conqueror’s Peak is a viable option too!
