With Iansan quickly becoming a staple in Genshin Impact team comps, many players are still figuring out how to fully optimize her buffs, manage her Nightsoul Points, and squeeze every drop of damage from her unique mechanics. In a fantastic breakdown from SevenPls on YouTube, we get a deep dive into how Iansan works—not just at C0, but all the way through C6.
From advanced movement interactions to snapshotting, constellation scaling, and even triple-element setups, this guide covers all the ways to make the most of Iansan’s support potential.
Understanding Iansan’s Nightsoul Points and Attack Buffs
At the core of Iansan’s kit is her Nightsoul Points system, which determines how much ATK she buffs to the active character. Many assume you must maintain 42+ points to keep her buff, but that’s not entirely true.
Key Mechanics:
- 🧠 Above 42 Nightsoul Points gives you a higher conversion: up to 27% of her total ATK to your DPS.
- ⚙️ Below 42 still gives a buff, just with lower conversion, but the same cap.
- 🧮 If your Iansan has very high ATK (like 4000+), you can reach the cap even with reduced conversion.
🔍 Takeaway: You don’t lose the buff below 42, you just lose efficiency. And with strong enough builds, that efficiency drop doesn’t always matter.
Movement Mechanics: How to Keep Nightsoul Points Stable
SevenPls explains how movement tracking is more nuanced than you’d expect. It’s not just running or dashing—even subtle body animations or micro-movements affect your point generation.
Tips for Keeping Buffs Active:
- 👣 Characters that plunge or dash between attacks naturally regenerate Nightsoul Points.
- 🧍 Standing still doesn’t stop the decay, but passive movements (like animations or auto-attacks) can help.
- 🧪 Certain combos—like Arlecchino’s three normals into dash—can be adjusted to stay above 42 Points.
🧠 Plunge, dash, or adjust positioning mid-rotation to maintain buffs—especially when not using characters from Natlan, who have passive synergy with Iansan.
Weapon Sync: Tamayuratei and Uptime Challenges
Many players run Iansan with the Tamayuratei—a solid event sword with high ATK and ER. But its 10-second buff doesn’t match Iansan’s 12s–15s burst duration, leading to awkward buff drop-offs.
Solution:
- 🔁 Consider combo splitting (Skill > Charged > Burst) to sync weapon buffs better with her kit.
- 🧭 Plan rotations around Iansan’s burst window, not the weapon’s timer.
📌 A strong weapon, but keep an eye on duration mismatches.
Cinder City: Triple Element Buff Setup
Iansan’s Cinder City passive is one of her most versatile features. It triggers when you cause a reaction involving an element your team is using, allowing her to buff multiple damage types simultaneously.
How to Trigger Triple Buffs:
- 🌋 In a Kinich + Mavika + Emily team, use Iansan’s Skill + Charged Attack to consume the burning aura (buffs Pyro), then Burst on Dendro aura (buffs Dendro).
- 💡 This allows both Pyro and Dendro teammates to benefit from Cinder City.
- 🌟 You can also set this up with Furina + Bennett + Electro, or other creative comps.
🧠 This opens the door to buffing hybrid teams—a rare and powerful mechanic for flexible team building.
Combo Optimization: Skill > Normal > Charged > Burst
Without C2, Iansan needs to manually activate her Charged Attack during the Night of Blessing state to gain +1 Nightsoul Point and her self-ATK bonus.
Suggested Combo:
- Skill
- Normal Attack
- Charged Attack
- Burst
At C2, you can skip this and just use Skill > Burst to get all effects instantly. But even post-C2, weaving in the charged can still boost rotation smoothness and uptime.
Constellation Scaling – How Much Does Iansan Boost Your Damage?
SevenPls tested Iansan in multiple team comps including Melt Mavika, Overload Chlorinde, and Kinich-Dendro reactions.
What You Gain from Constellations:
- C2: +30% more ATK to your DPS — ~5% team damage increase
- C5: Raises buff cap to 810 ATK — ~8% increase
- C6: Adds +25% DMG bonus — up to 18% total boost, depending on uptime
📌 However, C6 isn’t always active on all characters due to Nightsoul Point decay, so uptime matters.
Snapshotting: What Buffs Stick for the Full Duration?
Iansan’s buffs can be snapshotted by characters who retain stat bonuses throughout an ability’s duration—like Fischl, Beidou, and Xiangling.
Snapshot-Compatible Buffs:
- ✅ ATK buff (visible stat)
- ✅ Cinder City buff (applies pre-activation)
- ❌ C6 buff (requires ongoing uptime)
🧠 If you’re running Fischl, Xiangling, or similar off-field DPS units, snapshot Iansan’s buffs at peak for maximum effect.
Final Thoughts: Is Iansan Worth It?
Iansan isn’t just another ATK buffer. She’s a high-skill-ceiling support who:
- Offers unique movement-based resource management
- Enables multi-element buffing (Cinder City)
- Has amazing synergy with high-ATK and HP-scaling characters
- Is constellation-scalable with meaningful power spikes
If you enjoy strategic support roles, or want to create off-meta elemental comps, Iansan is absolutely worth building and learning.

Frequently Asked Questions About Iansan
Do you need 42 Nightsoul Points for Iansan to work?
No. 42+ Points give you better ATK conversion, but lower amounts still give the same max buff if your Iansan has high enough total ATK.
Is Tamayuratei a good weapon for Iansan?
Yes, it’s solid—but its 10s duration doesn’t align perfectly with Iansan’s 12s–15s burst buff. Be mindful of that desync when planning rotations.
How do you trigger Iansan’s Cinder City for multiple elements?
Trigger a reaction with each element your team uses. You can combo Skill + Charged to consume one aura, then Burst to react with another.
Is Iansan C2 worth it?
Yes. C2 simplifies rotations and gives a large ATK boost, helping unlock team-wide synergy and smoother buff uptime.
Which characters can snapshot Iansan’s buffs?
Characters like Fischl, Xiangling, and Beidou can snapshot most of Iansan’s buffs for maximum efficiency.
How much damage does Iansan C6 add?
Up to 25% bonus damage, adding around 14–18% team-wide DPS, depending on uptime and team composition.
