Build Up Interlink Levels to Use Ouroboros Chain Attacks

Xenoblade Chronicles 3 - Ouroboros Chain Attack

If one of your characters manages to reach Interlink Level 3 during combat, transforming and using the Chain Attack while in Ouroboros form will give you the option to perform an Ouroboros Chain Attack. This is a series of 2 special Chain Orders that deal a massive amount of damage when completed.

Note: Ouroboros Chain Attacks only become available after you unlock the Agnus Squad Ouroboros forms and finish Chapter 3 of the main story.

1
Hold Buttons zL and use Button L or Button R to cycle through characters.
2 When you have the character you want, start building up their Interlink Level by using Fusion Arts. At the same time, build the Chain Attack Gauge in preparation for the Ouroboros Chain Attack.

Once you charge the Chain Attack Gauge and reach Interlink Level 3, transform into an Ouroboros by pressing Left D-Pad.
4
When your character is in their Ouroboros form, press Plus Button to start the Chain Attack.
5 Select the Ouroboros Chain Order (this will be the only option) to start the Ourobros Chain Attack.
6 Complete it using the available party members in order to deal a massive amount of damage.
7 Repeat steps 5 and 6 when Reactivation occurs and a new Ouroboros Chain Order becomes available.
Note: When using this method, only 2 Chain Orders can be completed rather than the usual 3.

How to Raise Interlink Level

Complete Chain Orders of Interlinked Characters

Xenoblade Chronicles 3 - Ouroboros Reactivation

Aside from the Ouroboros-only Chain Attack, you can also get Ouroboros Chain Orders in a regular Chain Attack by completing the orders of Interlinked Characters. Complete the Chain Orders of either Noah & Mio, Taion & Eunie, or Lanz & Sena to get an Ouroboros Chain Order to spawn.

Note: You will know that you unlocked an Ouroboros Chain Order if the reactivation screen has a colored ring around it. This means an Ouroboros option will be available to use during the next chain.

Ouroboros Combat Tips

Ouroboros Combat Tips





Use Fusion Combos to Build Up Interlink Levels for Stronger Arts

Xenoblade Chronicles 3 - Use Fusion Arts

Some Ouroboros Arts will only get their full effects at Interlink Level 3. You can see your current level to the left of the Ouroboros symbol at the bottom left of the screen.

To level up the Interlink, use Fusion Arts as much as possible. This builds up the Interlink level to max, allowing you use Ouroboros Arts with their full effects in play.

How to Use Fusion Arts

Use the Ouroboros Form to Dodge Damage

Xenoblade Chronicles 3 - Use Ouroboros to Dodge Damage

While it is ideal to wait until Interlink 3 to transform, some of the more difficult fights will require you to dodge continuous or burst damage coming from enemies. If you find yourself at low HP and still taking aggro, consider transforming to become immune to damage.

This tactic is particularly useful when dealing with unique monsters that have a high damage Enrage Phase. However, do note that HP does not recover while in Ouroboros form even when healed by allies. Transforming while on low HP will mean you still re-appear later with low HP.

Do Not Set Paired Characters as Healers or Defenders

Xenoblade Chronicles 3 - Do Not Use Partnered Healers or Defenders

If you aren't partied with a Healer or Tank Hero, do not turn any of the pairs into your party's only Healers or Defenders. This avoids the problem of one pair transforming and leaving with with either no heals or no tanks to soak up damage.

Since Defenders and Healers are the core of combat when fighting difficult enemies, make sure not to double-up the class types of paired partners unless they are both Attackers.

Cancel Attacks Into Arts to Charge the Ouroboros Talent

Xenoblade Chronicles 3 - Cancelling Arts

In order to charge up the Ouroboros Talent Art (special attack, A button), make sure to cancel your attacks into Arts. Ouroboros skills have no cooldown, so it's all a matter of consistently chaining attacks into Arts until you have your Talent Art charged and ready.

To know if you are attack cancelling successfully, pay attention to your character when you use an art. You will know if you successfully canceled an attack if a blue ring appears after you use your Art.

How to Cancel Attacks

Pay Attention to the Overheat Meter

Xenoblade Chronicles 3 - Overheat and Cooldown

Ouroboros forms have a time limit in the form of the Overheat Meter, building up heat the longer your Ouroboros stays on the field. Actions such as using Arts also contribute to overheating, speeding up the process as you chain your Arts together.

You can view how much heat your Ouroboros form is getting by looking at the Ouroboros symbol (bottom left of screen) or at the Overheat bar next to your character icon on the left side of the screen. Once it hits the max amount, your Ouroboros will go into Cooldown mode, preventing you from using it for a time.

Cancel the Ouroboros Form Before Overheating

Xenoblade Chronicles 3 - Cancel Before Overheating

If you cancel the Ouroboros form before it overheats, the cooldown will be shorter. Make sure to cancel just before overheating to ensure that you are able to use the Ouroboros form multiple times in a single battle. To cancel your Ouroboros form, hit the Down D-Pad button while transformed.

How to Upgrade the Ouroboros

Farm SP to Purchase Upgrades

Xenoblade Chronicles 3 - Farm SP

Before you can start thinking about upgrading your Ouroboros, you will first need to farm Soul Points or SP. This special type of currency is used to purchase the many different upgrades, Skills, and Arts that are available for your Ouroboros.

You can usually get SP by completing quests, discovering special landmarks and locations, and even opening containers you find scattered around the world.

SP Farming Guide

Purchase Ouroboros Upgrades from the Soul Tree

Xenoblade Chronicles 3 - Soul Tree

The Sould Tree is a special upgrade menu that allows you to purchase upgrades for your Ouroboros. These include Skills, Arts and their upgrades, Overheat upgrades, and stat upgrades. To view the Soul Tree, open up the character menu and navigate to Characters > Interlink > Soul Tree.

Soul Tree Upgrade Priorities

Upgrade Type Priority Reason
Learn SkillLearn Skill Ouroboros have no skills when you first start out. Make sure to prioritize getting these from the Soul Tree to get a large boost in power.
Heat ControlHeat Control Scattered throughout the tree are Heat Gauge upgrades that gradually reduce the Ouroboros' rate of overheating. Prioritize these to get the most out of your transformations.
Enhance ArtEnhance Art The farther you get into the game, the more powerful your Ouroboros form has to be to deal with enemies. Prioritze Enhance Art upgrades to strengthen your primary source of damage.

Use the Soul Link to Share Upgrades

Xenoblade Chronicles 3 - Soul Link

Since Ouroboros Interlinks are between two characters, each character pair will get 2 Soul Link slots to use at the Soul Tree. Soul Links allow you to equip two upgrades from your paired character's Soul Tree, borrowing its power to strengthen your own.

For example, if Mio's Soul Tree has an upgrade that raises Critical Rate by 15%, then Soul Linking it to Noah's Ouroboros will grant his form +15% Critical Rate as well.

Can Be Soul Linked Cannot Be Soul Linked
・Learn Art
・Enhance Art
・Enhance Skill
・Enhance Talent
・Raise Ability
・Learn Skill
・Heat Gauge

Tip: Heat Gauge upgrades are your best bet for early Soul Linked upgrades. Since it is difficult to rack up enough Role Action Points to charge your Talent Art, longer Ouroboros times will greatly help the experience.
