Aino's Stat Priority
: Elemental Mastery / Energy Recharge
: Elemental Mastery
: CRIT Rate / CRIT DMGAino's own talent damage is very low, so it's best to build Elemental Mastery to increase her contribution to the Lunar Reaction damage. Since she usually gets a lot of Energy from her weapon, an Energy Recharge Sands is not needed. However, there's very little loss in not using an Elemental Mastery Sands, so you can use Energy Recharge instead if you want even more comfortable Energy.
Recommended Stats for Aino
Build recommendations assume a "decently built" level of artifact rolls alongside Favonius Greatsword. Using other weapons may increase or decrease certain stats relative to these recommendations.
Stats shown reflect what you would see on the stat screen, before any external buffs are applied.
Aino's Talent Priority
Aino's talents deal low damage and her buffs do not scale off them, so you can leave her talents unleveled and not miss out on much. But if you do level them, the Elemental Burst should be prioritized.
Aino's Best Constellations
Aino's best Constellations are her C1 and C6, as they give her some decent buffing for Lunar Reactions. C2 can also be useful, as it gives her some additional Hydro application. C4 gives more Energy refund, but she generally doesn't have issues casting her Elemental Burst anyway.
| Constellation | % of C0 | % From Previous Constellation |
|---|---|---|
| C0 | 100.00% | 100.00% |
| C1 | 103.04% | 103.04% |
| C2 | 103.19% | 100.14% |
| C3 | 103.25% | 100.06% |
| C4 | 103.25% | 100.00% |
| C5 | 103.28% | 100.04% |
| C6 | 110.09% | 106.59% |
