Arataki Itto is the "One and Oni" and the undisputed king of Geo DPS. He scales heavily with **DEF** and deals massive Geo DMG through his specialized Charged Attacks ("Arataki Kesagiri"). His playstyle is fast, aggressive, and requires a dedicated team of Geo supports to shine.

Pros

High sustained DPS with large AoE cleave.
Not reliant on reactions (consistent damage).
Extremely tanky due to high DEF stat.
Ushi (Skill) hits like a truck (high multiplier nuke).
Infinite stagger resistance during Charged Attacks.

Cons

Expensive Team: Needs Gorou (C6), Zhongli/Albedo/Chiori.
Burst reliant (No damage without Q).
High Energy Cost (70) with poor particle generation.
Struggles against Elemental Shields (Lectors/Heralds).

Quick Guide (TL;DR)

If you don't have time for the math, here is the cheat sheet.

Best Artifact: 4pc Husk of Opulent Dreams (Uncontested BiS).
Alt Artifact: 4pc Marechaussee Hunter (Only w/ Furina) or 4pc Bolide (Shielded).
Best Weapon: Redhorn Stonethresher (Signature - DEF Synergy).
Alt Weapon: Serpent Spine (BP - R5 Rivals Redhorn).
F2P Weapon: Whiteblind (Craftable DEF Stat Stick).
Main Stats: SANDS: DEF% | GOBLET: Geo DMG | CIRCLET: CRIT.
Talent Priority: Normal Attack = Elemental Burst > Elemental Skill.
Top Team: Itto + Gorou (C6) + Chiori/Albedo + Zhongli (Mono Geo).

Pro Tip: Stack Management: Always throw Ushi (E) *during* your burst. Ushi gives stacks when hit, deals massive damage, and generates particles. Throwing him outside of burst is a DPS loss.

Talent Breakdown & Mechanics

Normal Attack: Fight Club Legend

Superstrength Stacks: When Itto hits enemies with Normal Attacks, he gains stacks.
Arataki Kesagiri: Holding Attack when you have stacks unleashes a rapid series of slashes that consume no stamina. This is his primary damage source. The final slash is a massive nuke.
Mechanic: You must weave Normal Attacks to build stacks, then unleash Charged Attacks to spend them.

Elemental Skill: Masatsu Zetsugi: Akaushi Burst!

Ushi: Throws a bull (Ushi) that deals massive Geo DMG.
Stack Generation: Ushi grants a Superstrength stack when he hits an enemy, when he takes damage, and when he leaves. He also taunts enemies.
Strategy: Use Ushi during your Burst window for maximum damage (since Burst converts DEF to ATK).

Elemental Burst: Royal Descent: Behold, Itto the Evil!

Cost: 70 Energy | Cooldown: 18s
Raging Oni King: Converts Itto's Normal/Charged/Plunging attacks to Geo DMG.
DEF Conversion: Increases his ATK based on his DEF. Also increases ATK Speed.
Snapshot: The DEF-to-ATK conversion snapshots on cast. However, the Geo Infusion does not.

Talent Priority Order:

Normal Attack (Level 10) - Scales Kesagiri damage.
Elemental Burst (Level 9) - Scales DEF-to-ATK conversion.
Elemental Skill (Level 8) - Strong nuke (Ushi).

Stat Requirements & ER Thresholds

Itto generates almost no particles during his burst. He relies entirely on teammates (Gorou/Albedo) for energy.

Team Context	Weapon	ER Requirement
Mono Geo (w/ Gorou Fav)	Redhorn	130% - 140%
Mono Geo (w/ Gorou Fav)	Whiteblind (R5)	130% - 140%
C2 Itto	Any	100% - 110% (Base)

Substat Priority:

CRIT Rate / CRIT DMG (Target 70/160+)
DEF% (Primary scaling stat)
Energy Recharge (Until requirement met)
ATK% (Much less valuable than DEF)

Best Artifacts Comparison

Set Name	Role	Reasoning
4pc Husk of Opulent Dreams	BiS	Provides 54% DEF and 24% Geo DMG at max stacks. Tailor-made for Itto. Remember to stack it off-field before starting the Abyss.
4pc Marechaussee Hunter	Furina Team	Use only if paired with Furina. Gives 36% Crit Rate. Stronger than Husk if you have Furina buffs.
4pc Retracing Bolide	Shielded	Consistent 40% DMG bonus if shielded. Good if you have great pieces, but Husk is better.

Weapon Rankings

Weapon	Type	Performance	Notes
Redhorn Stonethresher	CRIT DMG	S+	Signature. Massive 88% Crit DMG. Increases Normal/Charged DMG based on DEF. Significantly stronger than any other option.
Serpent Spine (R5)	CRIT Rate	S	Battle Pass weapon. At R5, it is very close to Redhorn. Requires a shielder (Zhongli) to maintain stacks.
Whiteblind (R5)	DEF%	A (F2P)	Craftable. High DEF stats. Remember to hit enemies 4 times before Bursting to stack the passive.
Skyward Pride	ER%	A	Solves energy issues and vacuum blades benefit from Geo DMG bonus. Good comfort pick.

Constellation Value

Itto is fully functional at C0, but C6 turns him into a god.

C1: Stay a While and Listen Up - (QoL) Grants extra Superstrength stacks upon using Burst. Makes rotation much smoother and allows instant Charged Attacks.
C2: Gather 'Round, It's a Brawl! - (Energy) Restores energy and reduces cooldown based on the number of Geo party members. Solves his ER issues completely in Mono Geo.
C6: Arataki Itto, Present! - (Broken) Charged Attacks have +70% Crit DMG. 50% chance to NOT consume a stack when attacking. This allows for near-infinite slash chains.

Verdict: C0 is great. C6 is one of the strongest in the game.

Top Team Compositions

1. Mono Geo (The Gold Standard)

Main DPS: Itto
Buffer: Gorou (C6 is huge)
Sub-DPS: Chiori / Albedo
Shield: Zhongli

Why it works: Gorou buffs DEF and Geo DMG based on 3 Geo members. Zhongli shreds Geo RES. Chiori/Albedo deal off-field damage scaling on DEF. Itto drives it all.

2. Itto + Furina

Main DPS: Itto
Buffer: Furina
Buffer: Gorou
Healer: Xianyun / Jean / Bennett

Why it works: Furina gives a massive DMG% buff, which Itto lacks. You need a strong team healer to stack her Fanfare, but the damage ceiling is higher than Triple Geo if managed correctly.

Rotations & Combos

Standard C0 Combo:
Supports > Itto Q > Ushi (E) > Normal Attacks (Build Stacks) > Charged Attack Spam

Tip: Ushi hits hard. Always use him inside your Burst window. Also, remember to start the fight with Itto in the party but off-field to build Husk stacks.

Frequently Asked Questions

Do I need Gorou?
Yes. Gorou is to Itto what Faruzan is to Xiao. Without Gorou, Itto loses a massive amount of DEF and Geo DMG bonus. Gorou is essential.

Whiteblind vs. Serpent Spine?
R5 Serpent Spine is significantly better than R5 Whiteblind due to the DMG% and Crit Rate. However, Whiteblind is a very respectable F2P option.
