Main DPS	Solo Electro	140% - 160%

CRIT Rate / CRIT DMG (Target 1:2 ratio)
ATK% (Base damage scaling)
Elemental Mastery (For Aggravate/Reaction damage)
Energy Recharge (Until burst is consistent)

Best Artifacts Comparison

Set Name	Role	Reasoning
4pc Obsidian Codex	BiS Natlan	Tailor-made for Natlan characters with Nightsoul mechanics. Provides massive CRIT Rate when consuming Nightsoul points.
4pc Thundering Fury	Aggravate DPS	Excellent for Aggravate teams. Reduces Skill CD, allowing for more dashes and mobility.
4pc Gladiator's Finale	Generalist	Boosts Normal Attack DMG. A solid unconditional option if you have good substats.

Weapon Rankings

Weapon	Type	Performance	Notes
Staff of the Scarlet Sands	CRIT Rate	S+	Huge CRIT Rate stat stick. Passive converts EM to ATK, which is perfect for reaction-based builds.
Primordial Jade Winged-Spear	CRIT Rate	S	High Base ATK and ATK buff on hits. Very consistent for an on-field carry.
The Catch (R5)	ER%	A+ (F2P)	Boosts Burst DMG and Crit Rate. Great if you rely heavily on your Burst for damage.
Missive Windspear	ATK%	A (Event)	Provides ATK and EM buffs after triggering reactions. Solid F2P option for Aggravate.

Constellation Value

Iansan is a solid carry at C0, but C1 and C2 offer nice improvements to her fluidity and damage.

C1: Momentum Shift - (Speed) Increases Movement Speed and Attack Speed after using Elemental Skill. Makes gameplay smoother.
C2: Static Surge - (Energy) Restores Energy when hitting enemies with Electro attacks during Burst. Reduces ER needs.
C6: Thunderlord's Wrath - (Big Burst) Increases the duration of Burst state and adds powerful lightning strikes to Normal Attacks. Significant DPS increase.

Frequently Asked Questions

Is Iansan better than Cyno?
It depends. Cyno has longer field time requirements, while Iansan offers more burst-oriented damage and mobility. Iansan feels snappier for overworld and quick swap teams.

Do I need her signature weapon?
Not strictly. "The Catch" is a fantastic F2P alternative that provides ER and Crit Rate for her Burst. However, her signature weapon provides a significant damage boost.
