How to Recruit Io

Io is a key playable character right from the beginning of the main campaign. She is automatically included in the roster of party members in Chapter 1: The Western Frontier.

How to Play with Io

Io, a youthful mage with aspirations of elegance, wields the power to cast long-range spells and mend her party with recovery magic.

Io possesses two skills, triggered by the and buttons, with enabling players to execute a combo when executed accurately. This skill allows Io to unleash charged magical orbs, accumulating Mystic Vortex orbs with each successful attack. Meanwhile, initiates an aerial barrage, striking foes in a broad area. The number of orbs Io possesses determines the charging capacity of her attack, with maximum orb capacity unleashing a formidable assault. Monitoring the skills on the lower right side of the screen assists players in understanding when they can use specific skills, considering some have cooldowns.

As the sole spellcaster in the party, Io adeptly exploits enemy weaknesses through her elemental abilities. Her damage output remains consistently high, depending on the exploitable weak points of her adversaries. Armed with spells that cover wide ranges, Io effortlessly eradicates mobs while maintaining a safe distance. Buffing herself to hasten cast times, she strategically deploys skills and basic attacks to shower targets with magic. With four Mystic Vortex Orbs, her Stargaze attack delivers maximum damage across a sizable area. Players will derive satisfaction from mastering the timing and integration of her spellcasting and attacks, maximizing damage output in minimal time.

Io’s light skill produces a lightning ring that paralyzes enemies on impact. Holding down allows players to aim the circle toward enemies, and upon casting, Io gains a Mystic Vortex orb. The Concentration skill, activated by pressing , creates a circle granting Stout Heart, preventing interruptions and boosting Stargaze’s charge speed. This effect is known as Focused. Complementing light and plain attacks, Io’s fire skill inflicts a burn on nearby enemies, followed by a fireball that reduces enemy defenses by 10%.

An indispensable party member, Io excels in healing, a capability few characters possess. Pressing enables players to cast a large circle around her, healing and restoring allies’ HP. Mindful positioning in battle is crucial for Io, given her frailty and limited mobility common among spellcasters. Strategic timing of casting ensures safety and maximizes effectiveness.
