      . However, it only lasts for one turn. Io can therefore help cover for Athena on turns where the skill is on cooldown. In addition, the skill's Status Wind Switch.pngWind SwitchElemental DMG from foes turns into wind DMG
      allows Io to mitigate some damage against foes with off-element attacks.
    • Both characters can inflict, and benefit from Status Burned.pngBurnedHP is lowered on every turn
      . Since neither characters have Icon Bonus Debuff Success.png Debuff Success EMPs, both of them can cover for each other either when the other fails to inflict the debuff, or if the foe has a means to clear the debuff.
    • In the event that Athena also takes too much damage due to her increased Hostility, Io can heal her with Ability Sunny Days.png Sunny DaysRestore 50% of an ally's HP (Healing cap: 2500).
