Rebuilding Dorrick - Phase 4

By
Seren Morgan-Roberts

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

How to Start the 4th Phase of Rebuilding Dorrick

This stage of rebuilding Dorrick is available after completing the Missing Parts standard quest. As with other phases, you’ll be required to hand in specific items to build parts for Repapa. Certain builds will give higher progress % towards the completion bar, and you’re required to fill up the bar to complete the phase. You can build the same thing multiple times as well, which makes it a lot easier to complete when some items are easier to come by than others.

Speak to Repapa after completing the Missing Parts quest.

How to Complete the 4th Phase of Rebuilding Dorrick

As with the 2nd phase of Rebuilding Dorrick, you’ll need to collect collectibles from beyond just Aetia and Fornis. The more phases you complete the further you’ll need to go to find the required items. Below you’ll find a list of all possible builds, however, some are definitely easier to complete than others - especially if you want to do it in as little time as possible as well.

A lot of items can be found in the Pentelas and Keves Castle region, so you’ll have to reach these areas through the main story to be able to advance the Rebuilding Dorrick side story. Nailennial Shroom is a good build because it offers 40% completion and the items are relatively easy to find. Pentashrooms are a legendary item but they can be obtained from the Clifftop Hulk Fabricator which costs 1500G each time and you only need one to make the Naillennial Shroom. To access the Clifftop Hulk, you will need to be around level 45 or higher and to get Nail Stone you’ll also need to have progressed to the Keves Castle Region.

Filling Noirsalts is another good one to aim for as it offers 20% completion. Salty Soil is a legendary item, but once again you can obtain this from the Clifftop Hulk Fabricator, and utilising this, rather than trying to find them along Garf Mine Track, Pentelas Region, will save you some time! Filling Onions, though rare, can be purchased by a Nopon Merchant in Colony Gamma. And Muscat Noir (also rare) can be found with relative ease near the Penshia Portal in the Keves Castle Region. It’s recommended you try to build at least 2 of these as the items are easy to come by and it gives you 20% completion.

The Clifftop Fabricator is very useful for obtaining the rare Salty Soil and Pentashrooms too.

Matryzy Lime is also be another easy choice as you only need 2 different items. Matryos Carbon can be found around Torchlight Hill in the Aetia Region and Squeezy Lime can be found near Aquifer Exhaust, Pentelas Region. You do need x8 Squeezy Lime, however, and this build only gives you 10% Progress Completion. If you have a lot of Squeezy Limes, which are a pretty common drop, you’ll be able to make this build more than once.

Shepherd’s Limesteel and Mini Atmorine are also both relatively easy to collect if you have access to the Keves Castle Region. They both give 10% completion.
