Genshin Impact: Lan Yan Constellation Guide

In the vast world of Teyvat, Genshin Impact continuously introduces powerful characters that players can summon and build to suit their playstyle. One such character is Lan Yan, an adeptus and 5-star geo-elemental bow-wielder, who has become a fan-favorite due to her unique playstyle and design. To enhance her effectiveness in battle, players can unlock her Constellations, each providing valuable bonuses that elevate her abilities. In this guide, we will break down Lan Yan’s Constellations, offering a detailed look at what each one provides and how to best utilize them to maximize her potential.


What Are Constellations in Genshin Impact?

Before diving into Lan Yan’s specific Constellations, it’s important to understand what Constellations are. In Genshin Impact, Constellations are essentially a set of passive abilities that are unlocked as you gather duplicate copies of a character. For example, when you receive a second copy of Lan Yan (via pulling her from a banner), you’ll unlock her first Constellation, and so on with each subsequent copy.

Each of Lan Yan’s Constellations boosts her abilities in various ways, from improving her elemental abilities to enhancing her general combat potential. Unlocking these Constellations is a crucial aspect of maximizing her power, and understanding their effects will help you decide if you want to invest in her further.


Lan Yan’s Constellations: A Breakdown

C0 – No Constellation (Base Level)

At C0, Lan Yan is already a solid and versatile character. She can deal significant damage using her Normal Attacks, Charged Shots, and Elemental Burst. Her Elemental Skill, Starfall, deals damage and can also produce Geo Energy for party members. Even at C0, she’s a strong character that can function effectively in multiple team compositions. However, to truly unlock her potential, unlocking her Constellations is highly beneficial.

C1 – Starfall’s Blessing

Effect: When Lan Yan’s Elemental Skill, Starfall, hits an enemy, the ability gains the additional effect of generating Geo Energy. This can significantly reduce the cooldown time of her Elemental Burst, Celestial Bolt, and help trigger Elemental Reactions with ease.

How It Helps:
C1 allows Lan Yan to trigger Geo Resonance effects more efficiently and improves her overall energy generation, which is crucial for keeping her Elemental Burst up more frequently. This Constellation makes her a better energy battery, allowing her to provide more consistent support to your team.


C2 – Rising Sun

Effect: At C2, Lan Yan gains an additional damage buff on her Elemental Burst, Celestial Bolt, after performing a Charged Shot. Her attacks will now deal 20% more damage during the duration of her Elemental Burst.

How It Helps:
C2 increases Lan Yan’s damage output significantly. If you’re building her as a primary DPS, C2 is a game-changer. The added 20% damage boost to Celestial Bolt allows her to take on a more offensive role in your team composition, maximizing her damage potential during her Elemental Burst.


C3 – Starfall Ascension

Effect: At C3, Lan Yan’s Elemental Skill, Starfall, has its level increased by 3, enhancing its overall damage. This Constellation is excellent for improving the power of her Starfall and helps you achieve better burst damage in a shorter time frame.

How It Helps:
Increasing Starfall’s level directly translates to a significant damage boost. This Constellation is great if you want to improve her Elemental Skill for quick burst damage and energy generation, making her an even more efficient support character in your team.


C4 – Comet of Fate

Effect: At C4, when Lan Yan activates her Elemental Burst, she gains a damage buff for 15 seconds. Her Normal and Charged Attacks deal an additional 10% Geo damage.

How It Helps:
C4 allows Lan Yan to become even more potent with her Normal and Charged Attacks. Geo damage scaling is increased, and this buff makes her attacks hit harder, providing a noticeable increase in overall damage output. This Constellation is particularly valuable if you use her in a Geo-based team composition or with characters like Zhongli or Albedo.


C5 – Stellar Judgment

Effect: At C5, the level of Lan Yan’s Elemental Burst, Celestial Bolt, is increased by 3. This not only increases her overall damage but also improves her ability to contribute in longer fights.

How It Helps:
This Constellation is perfect for improving her Elemental Burst damage, making her burst window even more dangerous. This is an excellent upgrade for players who want to maximize Lan Yan’s burst potential, especially during prolonged fights or tougher bosses.


C6 – Celestial Battle Formation

Effect: Lan Yan’s Elemental Burst now has the added effect of boosting the damage of her Normal and Charged Attacks by 25% for the duration of the burst.

How It Helps:
C6 is a game-changing Constellation that allows Lan Yan to deal massive damage with her Normal and Charged Attacks during her Elemental Burst. If you want to maximize her role as a damage dealer, C6 ensures that she delivers some of the highest Geo damage possible in the game. It’s a perfect boost for both single-target and AoE combat.


Best Build and Playstyle for Lan Yan

  • Weapons: Lan Yan benefits from Bow weapons that increase ATK or provide Geo damage. Weapons like the The Viridescent Hunt or Skyward Harp can increase her Critical Rate and Attack to maximize her damage output.
  • Artifacts: The Retracing Bolide set is ideal for her, as it boosts Geo damage and gives a shield strength bonus when you use your Elemental Skill. Alternatively, a Wanderer’s Troupe set could enhance her Elemental Mastery if you’re looking for stronger reactions.
  • Team Composition: Lan Yan excels when placed in a team with Geo characters like Zhongli and Albedo, who can synergize well with her abilities. She can also work alongside Electro characters like Beidou or Raiden Shogun to trigger powerful Crystallize reactions.

Conclusion: Is Lan Yan Worth Raising?

Lan Yan is an incredibly versatile character who can fulfill both DPS and support roles effectively. While she excels in Geo-based compositions, her utility in teams with other elements also makes her a valuable asset. Unlocking her Constellations will further enhance her capabilities, and C6 is particularly game-changing, offering significant damage boosts to her Normal and Charged Attacks.

If you’re looking for a Geo archer that can provide excellent support and damage in battles, Lan Yan is definitely worth raising. With her unique abilities, Constellations, and synergy with various team compositions, she will undoubtedly prove to be a reliable and strong asset to your roster in Genshin Impact.
