Iansan Best Build Snapshot

Use this snapshot as the first build route, then adjust around your Energy needs, weapon inventory, artifact substats, and the teammates your account can support.

Slot	Recommended Build	Why It Matters
Artifact set	Scroll of the Hero of Cinder City x4	Use this as the first farming direction, then compare with substats.
Main stats	ATK% / / ER / ATK%	The main stats should support the official role and rotation pattern.
Substats	Energy Recharge, support scaling stat, then CRIT Rate if using Favonius	Solve uptime before pushing damage or utility stats.
Weapons	Calamity Queller, Favonius Lance, Engulfing Lightning, Prototype Starglitter	Choose the weapon that fixes the account's weakest stat first.
Talent priority	Elemental Burst > Elemental Skill > Normal Attack	Start with the talent that controls the real team window.
Team core	Iansan + ATK-scaling carry + off-field reaction slot + sustain	A good build fails if the team does not feed the right window.

How Iansan's Kit Works

Iansan is an Electro Polearm support, so her build should make buffs, Energy, and Natlan-style team timing reliable first. Read the skill notes as rotation guidance: which button starts the window, which action deserves talent investment, and which passive condition should change the build.

Weighted Spike: Check whether this attack string is part of the real rotation or only a filler action.

Thunderbolt Rush: Read this as the first rotation anchor because Skill timing often decides particles, state uptime, or off-field value.

The Three Principles of Power: Treat the Burst as a timing check: use it when it supports the team's main window instead of casting it on cooldown blindly.

Enhanced Resistance Training: Passive value should change artifact, team, or stat decisions only when the condition is easy to maintain.

Kinetic Energy Gradient Test: Passive value should change artifact, team, or stat decisions only when the condition is easy to maintain.

Night Realm's Gift: Hard Work and Drive: Passive value should change artifact, team, or stat decisions only when the condition is easy to maintain.

Iansan Talent Priority

Talent investment should follow the role, not the order of the talent screen. Delay crowns until the account has a stable team and weapon plan.

Icon	Talent	Build Note
	Weighted Spike	Normal Attack entry; invest only if the build actually spends field time attacking.
	Thunderbolt Rush	Skill entry; usually central when the kit creates the main support or damage state.
	The Three Principles of Power	Burst entry; prioritize when the rotation depends on its buff, damage, or utility.

Best Artifacts For Iansan

Farm the set that supports the rotation first. If the 4-piece set is weak, a better transition set with strong substats is the cleaner account decision.

Artifact Set	Use Case
Scroll of the Hero of Cinder City	Primary Natlan support set when Iansan can trigger the team buff reliably.
Noblesse Oblige	General team support fallback if nobody else holds it.
Emblem of Severed Fate	Use when Burst uptime is the limiting factor.
2-piece ATK + 2-piece Energy Recharge	Comfort transition set for unfinished accounts.

Iansan Main Stats And Substats

Slot	Best Stat	Notes
Sands	ATK%	Choose the stat that keeps the main rotation stable.
Goblet	/ ER	Match the role: elemental damage for DPS, utility stats for support.
Circlet	ATK%	CRIT helps damage roles; support builds may need utility or Favonius consistency.
Substats	Energy Recharge, support scaling stat, then CRIT Rate if using Favonius	Uptime and team value come before prettier sheet damage.

Best Weapons For Iansan

Weapon choice should fix the account's weakest point: Energy, scaling stat, CRIT balance, Elemental Mastery, or team support. Do not pull a weapon before the team is solved.

Weapon	Priority	Best Use Case
Calamity Queller	High-ATK premium option	Useful when Iansan's support value leans on ATK.
Favonius Lance	Best team Energy option	Often the practical choice when the whole team needs particles.
Engulfing Lightning	Premium ER option	Excellent if Burst uptime and ATK conversion both matter.
Prototype Starglitter	Craftable ER fallback	Accessible support option while farming.
The Catch	F2P Burst option	Use when Burst damage or uptime matters more than raw support stats.

Iansan Material Planning Notes

Level and talent gates are more predictable than artifact farming. Use the official material list as a checklist, then spend leftover resin on artifact upgrades after the gated items are covered.

Material	Qty	Farming Use
Mora	x2,172,500	Keep about x2,172,500 ready before final talent upgrades; Mora is the shared bottleneck across leveling, talents, and weapon work.
Vajrada Amethyst Sliver	x1	x1 for the Electro ascension gem path. Farm bosses first, then craft or convert only the missing tier.
Dracolite	x168	x168 total. Mark the farming route early because local-specialty style materials reset on a schedule.
Sentry's Wooden Whistle	x24	x24 from common enemies or crafting tiers. Pre-farm this before the last ascension push so resin is not blocked by overworld drops.
Vajrada Amethyst Fragment	x9	x9 for the Electro ascension gem path. Farm bosses first, then craft or convert only the missing tier.
Ensnaring Gaze	x46	x46 total. This is usually the boss or weekly-gated step, so finish it before chasing small artifact upgrades.

Is Iansan Worth Building Or Pulling?

Iansan is worth building when your account needs an Electro support for buff uptime and reaction teams. Heavy investment is less urgent if your current supports already cover Energy and damage buffs.

If you plan to spend for a banner, decide the team and pity path before the top-up. Genesis Crystals help only when the UID, server, guarantee, and budget are already clear.

Plan Genesis Crystals safely

Before pulling for Iansan, check pity, guarantee, UID, server, and package budget so the top-up step matches the account you actually play.

Iansan Constellation Value

Constellations are luxury upgrades until C0, the main weapon choice, and the team shell are settled. Dedicated mains can consider early constellations, but C6 should not define the baseline guide.

Constellation	Value	Recommendation
C0	Baseline	Build and test the character here first.
C1-C2	Early premium upgrades	Consider only if you already enjoy the role and own the support core.
C3-C5	Talent scaling	Usually less important than fixing artifacts, Energy, and team uptime.
C6	Whale investment	Powerful but unnecessary for standard recommendations.

Common Iansan Build Mistakes

Building personal Electro damage before support uptime.

Using Scroll when the team cannot trigger the condition reliably.

Skipping Favonius testing in Energy-hungry teams.

Letting Iansan take field time from the carry she should support.
