Xenoblade Chronicles: Definitive Edition Quest Guide - where to find all quests and which choices to make

Xenoblade Chronicles is a game chock full of quests to undertake. In fact, there are more than 400 quests found in the game, and a good chunk of quests are missable. Luckily, Xenoblade Chronicles: Definitive Edition has added a few tools to help quest completion go a little bit smoother, such as more icons labeling which enemies you need to defeat or which collectables you need to pick up in order to fulfill quest requirements.

Xenoblade has a ton of quests, and if you decide to take them all on, it can be quite the additional time commitment. If you just want to experience the storyline without bogging yourself down with quests, there’s certainly no need to complete all quests in the game. If you just pick up the quests you come across, and complete the ones you happen to as you work your way through the game, you’ll be fine. But this guide is one for completionists - those who want to make sure they find and complete every quest the game has to offer.

This page will list all the quests in the game, generally in the order in which they are available. It will also note which quests are missable due to story events or other reasons. Some quests do involve choices to make, and while none of these have any dramatic effect, we’ll offer advice and which choice is most optimal, due to a better reward or perhaps better Affinity/Reputation gain afterwards. This guide will NOT list story quests, as these cannot be missed and must be undertaken anyways.

This guide will also mention good times to work towards the Colony 6 Reconstruction, as this directly leads into more available sidequests.

A note about quests. Let’s repost a tip from our Tips Guide

Talk to NPCs twice, at different times of day, and before/after completing quests.

Xenoblade Chronicles has a somewhat strange Affinity/Reputation system, which is centered on how the game handles NPCs. All of the game’s named NPCs are categorized into five separate locations: Colony 9 Area, Central Bionis, Upper Bionis, Hidden Village, and Colony 6 Area. The game keeps track of every named NPC and places them on the Affinity Chart, which can be easily found in the main menu. You might be wondering: why bother filling out the Affinity Chart? The short answer is: for quests. Many of the game’s quests require NPCs to be placed on the Affinity Chart first, which requires talking to them. Additionally, talking to NPCs can also create links between various NPCs on the chart, which also is needed for some quests. Even more so, talking to NPCs after completing quests can boost your Reputation within the category (one of the five listed above), and some quests require your Reputation to be at a certain level before they will appear.

What makes this a little trickier is the NPCs often have multiple things to say, and you might miss Reputation boosts or Affinity Links if you only talk to each named NPC only once. So, you actually generally want to talk to each NPC twice, because they often will have more to say and Reputation boosts are sometimes found in the second dialogue. Additionally, completing quests will often change what NPCs have to say and their affinity for other NPCs, so you'll want to talk to NPCs again after completing quests. Even more additionally, NPCs change what they have to say at different times of day, with some affinity boosts only available at specific times. 

In short, talk to every named NPC twice, at multiple times, before and after completing quests. Named NPCs are shown as green dots on the mini-map. You don’t need to talk to unnamed NPCS.

Colony 9 Quests After Learning Monado Speed in Bionis Leg

• A Mysterious Light
  • There are two routes to take during this quest, but neither is clearly better.
• Out Like a Light?
  • Repairing the lamp is a slightly better option, due to better reward. You can do this by speaking to Arnaut, so you may have to change time. This will also require parts from the Ether Mine.

• The Road Home
  • This is mutually exclusive with a later but identical quest called "To Colony 6", which has a higher EXP/money reward, but you'll have to put off the reconstruction of Colony 6 for a while. Also, completing this quest by talking to Juju will move the NPCs from Refugee Camp to Colony 6, expiring any quests not yet done there. Make sure you've complete all the Bionis Leg quests first before doing this one.
• What is Love?!
  • You must have completed Spirits Raised
• What is Courage?!
  • You must have completed Spirits Raised, either route is the same.
• Matryona's Answer
  • You must have completed Spirits Raised. The Lake Drop route for this quest is the better option.

  • Don't attempt until Making a New Path is completed, else you have to take on a Level 90 monster ;(
• A Selfish Girl's Mistake
• Satata's Younger Brother
• Rest in Peace
  • Cannot complete until Makna Forest

Here is a good time to get all Colony 6 Reconstruction categories to Level 1. This will then allow you do The Gem Man's Invention quest in Colony 9, which gives you the portable gem furnace.

Colony 9 Quests After Riki Joins Party

• Desiree's Future
  • This quest can be difficult to unlock at this time, due to the high Colony 9 Reputation needed, but it should be able to be done. Make sure to do all other Colony 9 and Tephra Cave quests, talk to all named NPCs multiple times at different times to boost reputation, talk to Desiree even if she doesn't have a quest icon.
  • The Soldier route is the better route for affinity.
  • This will unlock Shulk's Pessimism skill tree
• A Young Captain's Challenge
  • Neither the Sword or Shield route is better. They'll lead to different quests as a followup, but the ultimate final reward is nearly the same. Shield gives a Daze Gem while Sword gives a Topple gem. That's it.
• The Old Soldier's Test
  • To activate the quest, talk to Dionysus and say "He's too old for that girl." This will lower the affinity bond between Jan and Dionysus but raise Colony 9 Reputation overall
• A Big Brother's Fight OR A Little Brother's Fight [mutually exclusive quests]
  • Completing A Little Brother's Fight - giving the pollen to Jiroque - is a slightly better option for affinity. The option you choose will also affect which follow-up quest you get.
• Thawing Relations OR A Place to Come Home To [mutually exclusive quests]
  • Depends if you picked Jiroque or Zakazu
• Betty's Gift OR Desiree's Apology [mutually exclusive quests]
  • Depends on which route you chose for 'Desiree's Future, can't be completed until Eryth Sea

Frontier Village Quests after Alcamoth

• Dangerous Ambition

• Getting a Member's Card
  • This is listed as an Alcamoth quest in-game, placed here in this guide for convenience
