When it comes to maximizing your team potential in Genshin Impact, 4-star characters with full constellations can often rival or even outperform some 5-star options at C0. As we move through 2025, several 4-star characters have established themselves as exceptional investments when built to C6. Let's explore the most valuable 4-star characters worth taking all the way to their maximum constellation potential.

Why C6 4-Stars Matter

In Genshin Impact's evolving meta, fully constellated 4-star characters offer tremendous value for players. While 5-stars often steal the spotlight, many veteran players know that C6 4-stars can:

  • Provide comparable performance at a fraction of the primogem cost

  • Unlock game-changing mechanics through their final constellations

  • Fit seamlessly into meta teams as supports or sub-DPS

  • Become accessible faster through standard banner pulls and regular rate-ups

Top-Tier C6 4-Star Supports

Xingqiu - The Hydro Enabler

Xingqiu remains one of the most valuable 4-star characters to C6 in 2025. His final constellation provides:

  • 50% increased Hydro application through his rain swords

  • Significantly higher damage output

  • Energy regeneration that solves his burst uptime issues

His C6 is considered the optimal constellation benchmark in Genshin's meta, making him invaluable in many Vaporize, Freeze, and even newer Lunar-Bloom teams that rely on consistent Hydro application.

Bennett - The Unrivaled Buffer

Despite being available since launch, Bennett's C6 remains controversial but potentially powerful:

  • Provides a massive 15% Pyro DMG bonus to characters inside his burst

  • Infuses melee weapons with Pyro (both a benefit and limitation)

  • Can enable certain Pyro-focused teams to reach their maximum potential

While some players leave Bennett at C5 to maintain his versatility, his C6 can be transformative for Pyro-focused teams with characters like Xiangling.

Exceptional C6 4-Star Sub-DPS Units

Xiangling - The Pyro Powerhouse

Xiangling is perhaps the most enduring 4-star in Genshin's meta history, and her C6 only enhances her capabilities:

  • Provides 15% Pyro RES reduction during Pyronado

  • Increases team Pyro DMG by 15%

  • Works perfectly with the current Pyro Traveler meta teams

Her ability to deal off-field Pyro damage while enabling reactions makes her C6 one of the most impactful constellation upgrades for any 4-star character.

Fischl - The Electro Turret

Fischl at C6 transforms from a solid Electro applicator to an exceptional off-field damage dealer:

  • Oz performs a joint attack with your active character

  • Dramatically increases her Electro application rate

  • Significantly boosts overall team DPS in Electro-focused teams

With the rise of Lunar-Charge reactions in Nod-Krai, C6 Fischl has found renewed value in the current meta.

Surprising C6 Contenders in 2025

Sucrose - The EM Queen

With the introduction of characters like Flins, Aino, and Ineffa, Sucrose has seen her value increase substantially:

  • C6 grants a 20% Elemental DMG bonus to the swirled element

  • Provides unmatched Elemental Mastery sharing

  • Works exceptionally well in Lunar-reaction focused teams

Her ability to boost both EM and Elemental DMG makes her C6 increasingly valuable in the current reaction-heavy meta.

Layla - The Cryo Shield Support

Layla has seen a significant rise in usage with the shift toward Lunar-Bloom teams:

  • C6 increases her shield strength and skill damage

  • Provides excellent Cryo application for reaction teams

  • Works well with newer characters like Nefer and Ineffa

Building Around Your C6 4-Stars

When investing in C6 4-star characters, consider these tips:

  1. Focus on characters that complement your existing 5-stars

  2. Prioritize universally useful supports like Xingqiu and Bennett

  3. Consider the current meta reactions (Lunar-Bloom and Lunar-Charge are dominating in 2025)

  4. Look for characters with constellations that fix their kit limitations

Conclusion

While Genshin Impact constantly introduces new 5-star characters that reshape the meta, well-built C6 4-star characters remain some of the most valuable assets in your account. Characters like Xingqiu, Bennett, Xiangling, and Fischl continue to be mainstays in top-tier teams even after years of new character releases.

As Nod-Krai continues to introduce new elements and reactions, certain C6 4-stars have found renewed value in enabling these mechanics. Whether you're a new player looking to maximize your resources or a veteran seeking to optimize your teams, these C6 4-star characters represent some of the best investments you can make in Genshin Impact.

Remember that team synergy ultimately matters more than individual character power, so build your C6 4-stars with your overall team composition in mind.
