Okay fam, Iansan is FINALLY playable in Genshin 5.5, and honestly? She's lowkey cracked as a support. Remember her being a big deal in the Natlan story? Well, she brings that same energy to your team comps, dishing out insane ATK buffs that'll make your main DPS go brrrrr. Think Bennett-level vibes, but with her own unique flavor – she demands mobility and mastering her Nightsoul mechanic. It's not just plop down a circle and vibe; you gotta move, people!

Seriously, her kit screams 'buff queen'. Similar to Shenhe (another ATK buff goddess), Iansan's buffs scale off her TOTAL ATK, not just base ATK. This means stacking ATK% on her gear is the name of the game. Get that number high, and your whole team hits like trucks. Aiming for around 2500 ATK is the sweet spot for her level 10 Burst buff. Got her C5? Congrats, you whale! That pushes her Burst to level 13, and your ATK target jumps to a spicy 3000. Gotta catch 'em all... ATK% substats, that is!

Artifacts: Buff City or Energy Town?

So, what's the best drip for our Natlan queen? Hands down, the Scroll of the Hero of Cinder City set is her BiS. Here's why it slaps:

• 2-Piece: Energy Recharge +20% (Yasss, ER is life).

• 4-Piece: When she's off-field (which she often is), it can boost the entire team's Elemental DMG by up to 40%. Forty percent! That's no joke.

This set synergizes perfectly with her needing high Nightsoul uptime. In theory, you can keep that juicy 40% DMG buff rolling almost constantly. Chef's kiss!

But wait! What if someone else on your squad is already rocking the Scroll? Or maybe you just don't have a good set yet? Enter Noblesse Oblige. The classic support set is always a solid Plan B:

• 2-Piece: Elemental Burst DMG +20% (Nice little bump for her own damage).

• 4-Piece: Using her Elemental Burst gives the whole team a sweet +20% ATK buff for 12 seconds.

This synergizes super well with her support role. BUT – and this is a big BUT – Noblesse Oblige's 4-piece effect does NOT stack. If Bennett or someone else is already packing Noblesse, putting it on Iansan is kinda wasted potential. In that case, stick with the Scroll set or maybe explore other options. Diversity in buffs is key!

Stat Goals: ATK is Queen, ER is Her Handmaiden

Building Iansan isn't rocket science, but you gotta hit those thresholds. As mentioned, ATK is KING (or Queen!). Prioritize ATK% sands, ATK% Goblet (seriously, skip the Electro DMG Goblet for her support build), and an ATK% Circlet. Sub-stats? Chase ATK%, Energy Recharge (ER), and maybe some CRIT Rate/DMG if you're using Favonius Lance or want a smidge of personal damage.

Now, ER... oh boy, her ER needs can be spicy. Generally, you're looking at 150-200% ER. That sounds rough, but chill! There are ways to ease the pain:

• C1: Her C1 constellation is a massive ER help. Game-changer!

• Double Electro: Run her with another Electro character for those sweet Electro particles.

• Batteries: Characters like Raiden Shogun or Fischl can feed her energy like nobody's business.

If you meet her ER needs through these methods or substats, you can even consider an ATK% Sands instead of an ER one. Flexibility, baby!

Weapon Wars: What Makes Her Buffs POP?

Choosing Iansan's weapon is all about maximizing ATK and managing ER. Let's break down the contenders:

Weapon (Rarity)	Why It's Good	Downside
Calamity Queller (5★)	Massive Base ATK! Passive gives huge ATK% boost after Skill. BiS for max buffs.	Zero ER. Requires perfect ER substats/teams or her C1. High investment.
Engulfing Lightning (5★)	Huge ER substat. Converts ER into ATK! Balances her needs perfectly. Raiden's loss is Iansan's gain!	Less raw ATK than Calamity Queller.
Tamayuratei No Ohanashi (4★)	Best F2P option. ER substat + ATK% passive + speed boost? Solid! Synergizes well.	Lower base stats than 5★s.
Favonius Lance (4★)	ER substat is high. Passive generates extra particles for team. Great if ER is still a struggle.	Doesn't boost her ATK directly.
Skyward Spine (5★)	High Base ATK + ER substat. A decent stat stick if you have it spare.	Passive is kinda useless for her. Overkill ER sometimes.

Honestly, she's surprisingly flexible. You don't absolutely need a 5-star weapon. A well-refined Tamayuratei No Ohanashi or Favonius Lance can get the job done brilliantly for most players. Calamity Queller and Engulfing Lightning are amazing if you have 'em, but don't stress if you don't.

The Verdict? She Slays.

Iansan brings a unique, high-skill-ceiling support style to Genshin. Mastering her Nightsoul flow and team mobility is key to unlocking her full potential – that massive ATK buff and potential Elemental DMG boost are absolutely worth the effort. Building her revolves entirely around hitting those ATK targets (2500/3000) and managing her ER needs (150-200%, mitigated by constellations/teams).

Is she powercreeping Bennett? Nah, different vibes. But she offers a potent alternative for ATK buffing, especially in mobile teams or where Bennett's circle feels limiting. The Scroll set is her dream outfit, Noblesse is a reliable backup. Weapon choices are plentiful, from uber-whale Calamity Queller down to the trusty Favonius Lance.

So yeah, if you pulled for her, congrats! She's got that sauce. Just remember: ATK%, ER management, and keep moving! Now go unleash some buffed-up havoc in Teyvat. Peace out!
