Xenoblade Chronicles 3 Mio - Best Build & Classes

Mio is a playable character in Xenoblade Chronicles 3, and she’ll be a mainstay of your party for quite some time. Along with Noah, she is one of the two main protagonists.

Mio is an Off-Seer who hails from Agnus, one of Keves’s greatest rivals. As a result of the events that led to her and her companions joining Noah’s group, she develops into an exceptionally useful member of the party.

So, to help you get the most of Mio in Xenoblade Chronicles 3, we’ve prepared a quick guide to the best Arts and Class builds for her below.

Xenoblade Chronicles 3 Mio Best Build

Xenoblade Chronicles 3 Mio Best Classes

  • Heavy Guard – Has access to powerful skills that can revive fallen comrades, and Aggro can be directed with the help of Taunt Arts.
  • Guardian Commander – Gain complete Aggro by using two distinct Arts and Excellent Skills that mitigate damage dealt to allies.

Mio’s initial class in combat is Xephyr, and her initial Role is that of a Defender. These defenders stay alive thanks to their chakrams and their nimble reflexes. As you gain experience and level up, you’ll unlock new classes, giving you more freedom to create your ideal character build.

Both classes have potent skills that Mio can put to good use, but the decision of which to adopt should be influenced by the needs of your actual Party.

These are essential gems to have on your defenders that rely on avoiding attacks rather than reducing its damage output. Doublestrike boosts your probability to strike twice in a single auto-attack, while Tailwind increases your agility. Additionally, Steady Striker increases your character’s attack speed, which immediately improves your damage per second and also accelerates the cooldown of your auto-attack.

When utilizing the Zephyr class, Mio can prevent more damage from the enemy if she equips accessories that boost her attack, health, and agility. Given that her role is that of a Defender, any things that raise the amount of aggro to enemies should be equipped whenever possible.

  • Radiant Ring – Target Lock
  • Deadly Twister – Evades enemy attacks while Art is active.
  • Full Moon Drop – Interlink Lv3: Break all

As for the best Ouroboros Arts you should choose in the early to mid game, Deadly Twister allows you to prevent damage while Art is active while Radiant Ring helps you lock onto and deal damage to an opponent while they cope with your attacks. In combat, Full Moon Drop can be swapped out for Jaguar Slash if generating combos isn’t your primary aim.
