Best Iuno teams

Augusta Electro HeavySS

Iuno amplifies Heavy Attack while healing; Lynae raises the whole team ceiling — the best Electro team so far.

Augusta Electro SustainSS

Iuno's Heavy Attack buffs and Outro Skill amplification plug straight into Augusta's Heavy-Attack-driven Electro kit, and her healing plus stamina regen keep the rotation running without gaps; Shorekeeper's Liberation field adds continuous healing and a Crit buff so both units can commit fully to their Heavy Attack windows.
