Aino is a great Sub-DPS unit capable of dealing decent damage while excelling at applying Hydro to enemies. Her kit revolves primarily around her Burst, so this build will focus on maximizing its potential.

Her stat priority is straightforward — stack as much Elemental Mastery as possible, as it directly amplifies her damage output through Elemental Reactions.

Alongside that, make sure to invest in enough Energy Recharge to keep her Burst available every rotation, since it's the core of her playstyle. Without consistent Burst uptime, her overall contribution to the team drops significantly.

Notice: Her best weapon is Flame-Forged Insight which is a Event Exclusive weapon.
