Aino is a brand new 4-star character in Genshin Impact 6.0, and despite being a free character, she possesses a lot of exciting potential. If you're looking to build Aino to be as powerful and effective as possible, this article will help you maximize her strength in your team. Let's explore with Hobiverse how to build Aino to take full advantage of her benefits, especially in the land of Nod-Krai.
Aino's Strength in Genshin Impact
Aino is not a character who can easily impress with direct attacks. However, what makes her special is her strong support capabilities through her Elemental Burst and buffs for her teammates. She is a Hydro Claymore character and is especially useful in Nod-Krai teams.

The key to building Aino lies in optimizing her Elemental Burst usage and maintaining the Mooncall state, a new mechanic for characters appearing in Nod-Krai. When Aino uses her Elemental Burst, she summons a rubber duck that can continuously fire Hydro attacks. This duck stays in place but can attack enemies within a fairly wide range with an impressive firing rate of 1.5 seconds/hit. After 2 hits, it applies a Hydro aura to the target to maintain elemental efficiency.
This attack may not seem strong at first glance, but with at least two Nod-Krai characters in the team (achieving the Mooncall - Radiant state), the rubber duck's firing speed increases to 0.7 seconds/hit and then switches to AOE (area of effect) attacks, making her an extremely effective wide-area Hydro applicator.
With this skill set, Aino can play a major role in supporting elemental reactions, especially Dendro reactions like Bloom or Hyperbloom, helping to increase damage for teammates without directly dealing damage.
Mooncall: Nod-Krai's New Mechanic
If you're new to Mooncall, imagine it as a form of elemental resonance but exclusive to Nod-Krai characters.
With at least one Nod-Krai character in the team, Mooncall reaches the Glimmering state, and with two Nod-Krai characters, this state is elevated to Radiant. Depending on the Mooncall state, the team will receive various buffs, from increased damage for elemental reactions to increased combat resource generation.
While previous mechanics affected characters from specific regions, Mooncall spreads to the entire team, even if they are from different areas. This is an important factor that enhances Aino's flexibility in diverse team compositions.

Artifact Choices for Aino
When building Aino, you need to focus on optimizing stats that allow her to quickly recharge energy and maintain her Elemental Burst continuously. Since Aino primarily serves as a Hydro support and elemental reaction trigger, you don't need to invest too much in her personal damage.
An ideal artifact set for Aino is Song of Crescent Moonlight, a new artifact set in Nod-Krai, which increases Energy Recharge by 20% and provides a significant amount of EM for the entire team. This set will help you not only maintain Aino's Elemental Burst but also buff other characters in the team.
Additionally, if you want to enhance the effectiveness of transformative reactions like Bloom or Hyperbloom, you can use Noblesse Oblige or Deepwood Memories, depending on your team composition and strategy.
Suitable Weapons for Aino
In weapon selection, the most important thing is to ensure Aino can quickly recharge energy to use her Elemental Burst continuously. One of the excellent choices for her is Refined Wisdom S5, a free 4-star weapon that you can obtain in Genshin Impact 5.8. This weapon not only provides a stable amount of EM but also helps Aino recharge energy every 15 seconds, allowing her to maintain her Elemental Burst continuously.
Additionally, Favonius Greatsword S5 is an undeniable choice. This weapon not only helps reduce the energy recharge needs of the entire team but also helps Aino generate energy particles to support the DPS in the team.

How to Effectively Build Aino
To effectively build Aino, you don't need to focus too much on increasing her direct damage, as she primarily serves as a support. The most important thing is to ensure she has enough energy to use her Elemental Burst continuously and maintain Mooncall for the entire team.
Additionally, with the right weapons and artifacts, Aino will help increase the elemental reaction capabilities of the entire team, especially Dendro and Hydro reactions. Make sure Aino can synergize well with other characters in the team to maximize the effectiveness of her skills and buffs.
In summary, Aino is a free 4-star character who brings incredible value to the team, especially when built correctly. Her ability to apply wide-area Hydro, provide EM buffs, and trigger Mooncall for the entire team are Aino's strengths, making her an important factor in many strategies.
