Flins is a 5-star Electro Polearm character who serves as the primary Lunar-Charged on-field DPS, specializing in sustained Electro damage and reaction-based burst windows. His kit revolves around activating Manifest Flame through his Elemental Skill, empowering his Normal Attacks and unlocking powerful special abilities that repeatedly trigger Lunar-Charged damage.
Once in Manifest Flame, Flins shifts into an aggressive combat stance where his Normal and Charged Attacks deal Electro damage and his Elemental Skill transforms into Northland Spearstorm, a fast-cooldown attack that enables access to his special Elemental Burst. His gameplay focuses on repeatedly cycling Normal Attacks and Spearstorm to trigger Thunderous Symphony, creating frequent Lunar-Charged damage instances.
Unlike many Electro characters that rely purely on reaction frequency, Flins scales both direct Electro damage and Lunar-Charged reaction damage. His passive talents convert Electro-Charged into Lunar-Charged and further amplify its scaling based on his ATK, making him the central driver of Lunar-Charged teams.
Flins performs best in teams that maintain consistent Hydro application, allowing thunderclouds from Lunar-Charged reactions to remain active while he continues attacking on-field.
How Flins Helps:
- Lunar-Charged Reaction Core: Flins converts Electro-Charged into Lunar-Charged, enabling the thundercloud mechanic that deals continuous Electro damage to enemies affected by Hydro and Electro.
- Empowered Attack State: After activating Manifest Flame, Flins gains enhanced Electro Normal Attacks and access to special Skill and Burst variants that significantly increase his damage output.
- Frequent Burst Windows: Using Northland Spearstorm temporarily replaces his Burst with Thunderous Symphony, allowing him to unleash faster and more frequent Lunar-Charged damage.
- ATK-Scaling Reaction Damage: Flins increases the base damage of Lunar-Charged reactions based on his ATK, making ATK investment valuable for both his personal damage and team reaction output.

Lunar-Charged
Electro + Hydro
Lunar-Charged teams revolve around converting standard Electro-Charged into Lunar-Charged, a unique reaction that creates thunderclouds which periodically deal scaling Electro DMG to nearby enemies. Flins acts as the central on-field DPS, repeatedly triggering Lunar-Charged through his enhanced Electro attacks while Hydro teammates maintain consistent application.
Once Lunar-Charged is active, the thundercloud effect allows damage to continue even while Flins performs his Normal Attack strings and special abilities. This creates a steady stream of reaction damage that complements his direct Electro output, making sustained Hydro application extremely important for maintaining reaction uptime.
Below is an example of a Lunar-Charged team with Flins as the Main DPS, Ineffa as the Sub DPS, and Columbina and Sucrose as the Support.

If you don't have Columbina, you can replace her with Aino. Below is an example of a Lunar-Charged team with Flins as the Main DPS, Ineffa as the Sub DPS, and Aino and Sucrose as the Support.

If you don't have Ineffa, you can replace her with Iansan, Kujou Sara, or Fischl. Below is a 4-star example of a Lunar-Charged team with Flins as the Main DPS, Iansan as the Sub DPS, and Aino and Sucrose as the Support.


Damage Showcase
Here is a showcase on how to use the Lunar-Charged team composition presented in this guide, containing Flins, Ineffa, Sucrose, and Columbina.
We begin by preparing with the support characters. We begin by preparing with the support characters. Ineffa's Elemental Skill (E) then Elemental Burst (Q), Columbina's Elemental Skill (E) then Elemental Burst (Q), and Sucrose's Elemental Skill (E) then Elemental Burst (Q).

We can that swap in Flins.


Pros
- Exceptional Lunar-Charged Driver: Flins is currently the most reliable character for consistently triggering Lunar-Charged, making him the centrepiece of Electro + Hydro reaction teams.
- Strong Sustained DPS: During Manifest Flame, Flins maintains high on-field damage through empowered Normal Attacks and frequent Skill usage.
- ATK-Scaling Reaction Damage: His passives increase Lunar-Charged damage based on his ATK, meaning investment improves both his personal damage and reaction output.
- High Reaction Uptime: With proper Hydro support, Flins can maintain near-constant Lunar-Charged thunderclouds, allowing damage to continue even between attack strings.
- Fast Ability Cycling: Northland Spearstorm enables access to Thunderous Symphony, allowing for frequent bursts of Lunar-Charged damage during his field time.
Cons
- Highly Dependent on Hydro Teammates: Without consistent Hydro application, Flins cannot reliably trigger Lunar-Charged, causing a large drop in damage.
- Limited Team Options in the Current Version: Many of his strongest teams rely on specific 5-star characters like Ineffa and Columbina, making team building restrictive for some players.
- Requires Extended Field Time: Flins needs sustained on-field presence to fully utilise Manifest Flame and maintain reaction uptime.
- Stat Demanding: Balancing ATK, CRIT stats, and Energy Recharge can be challenging, especially when optimising both personal damage and reaction scaling.
- Less Effective Outside Lunar-Charged Teams: While still functional, Flins loses a large portion of his value if Lunar-Charged reactions are not consistently triggered.
