Normal Attack
Performs up to 4 consecutive strikes.
When the 2nd and 4th strikes hit opponents, Itto will gain 1 and 2 stacks of Superlative Superstrength, respectively.
Max 5 stacks. Triggering this effect will refresh the current duration of any existing stacks.

Additionally, Itto's Normal Attack combo does not immediately reset after sprinting or using his Elemental Skill, "Masatsu Zetsugi: Akaushi Burst!"

Charged Attack
When holding to perform a Charged Attack, Itto unleashes a series of Arataki Kesagiri slashes without consuming Stamina. Instead, each Arataki Kesagiri slash consumes 1 stack of Superlative Superstrength. When the final stack is consumed, Itto delivers a powerful final slash.

If no stacks of Superlative Superstrength are available, Itto will perform a single Saichimonji Slash.

Plunging Attack
Plunges from mid-air to strike the ground, damaging opponents along the path and dealing AoE DMG upon impact.

Hurls Ushi, the young akaushi bull and auxiliary member of the Arataki Gang, dealing Geo DMG to opponents on hit.
When Ushi hits opponents, Arataki Itto gains 1 stack of Superlative Superstrength.

Ushi will remain on the field and provide support in the following ways:

• Taunts surrounding opponents and draws their attacks.
• Inherits HP based on a percentage of Arataki Itto's Max HP.
• When Ushi takes DMG, Arataki Itto gains 1 stack of Superlative Superstrength. Only 1 stack can be gained in this way every 2s.
  Ushi will flee when its HP reaches 0 or its duration ends. It will grant Arataki Itto 1 stack of Superlative Superstrength when it leaves.

Hold
Adjust throwing angle.

Ushi is considered a Geo construct. Arataki Itto can only deploy 1 Ushi on the field at any one time.

Time to show 'em the might of the Arataki Gang! For a time, Itto lets out his inner Raging Oni King, wielding his Oni King's Kanabou in battle.
This state has the following special properties:

• Converts Itto's Normal, Charged, and Plunging Attacks to Geo DMG. This cannot be overridden.
• Increases Itto's Normal Attack SPD. Also increases his ATK based on his DEF.
• On hit, the 1st and 3rd strikes of his attack combo will each grant Arataki Itto 1 stack of Superlative Superstrength.
• Decreases Itto's Elemental and Physical RES by 20%.

The Raging Oni King state will be cleared when Itto leaves the field.

1) Redhorn Stonethresher (ATK: 542 • Crit DMG: 88.2%)

DEF is increased by 28/35/42/49/56%. Normal and Charged Attack DMG is increased by 40/50/60/70/80% of DEF.

2) Serpent Spine (ATK: 510 • Crit Rate: 27.6)

Every 4s a character is on the field, they will deal 6/7/8/9/10% more DMG and take 3/2.7/2.4/2.1/1.8% more DMG. This effect has a maximum of 5 stacks and will not be reset if the character leaves the field, but will be reduced by 1 stack when the character takes DMG.
Note: When using Husk of Opulent Dreams, Serpent Spine stacks are prioritized over Husk of Opulent Dreams stacks due to their conflicting nature in gaining stacks (Off-field and on-field).

3) Skyward Pride (ATK: 674 • Energy Recharge: 36.8)

Increases all DMG by 8/10/12/14/16%. After using an Elemental Burst, Normal or Charged Attack, on hit, creates a vacuum blade that does 80/100/120/140/160% of ATK as DMG to opponents along its path. Lasts for 20s or 8 vacuum blades.
Note: Can be a great or bad weapon for Itto depending on your ER needs. The less Energy Recharge you need (due to particle generation from your party members or ER from subs), the less useful this weapon becomes.

4) Whiteblind (ATK: 510 • DEF: 51.7)

On hit, Normal or Charged Attacks increase ATK and DEF by 6/7.5/9/10.5/12% for 6s. Max 4 stacks. Can only occur once every 0.5s.
Note: Your rotations often start with 1 stack of this weapon, and due to Itto's Burst snapshotting DEF on cast, you're unable to take advantage of further DEF% from the stacks.

1) Husk of Opulent Dreams

2-Piece Bonus: DEF +30%
4-Piece Bonus: A character equipped with this Artifact set will obtain the Curiosity effect in the following conditions: When on the field, the character gains 1 stack after hitting an opponent with a Geo attack, triggering a maximum of once every 0.3s.
When off the field, the character gains 1 stack every 3s. Curiosity can stack up to 4 times, each providing 6% DEF and a 6% Geo DMG Bonus. When 6 seconds pass without gaining a Curiosity stack, 1 stack is lost.

2) Desert Pavilion Chronicle

2-Piece Bonus: Anemo DMG Bonus +15%
4-Piece Bonus: When Charged Attacks hit opponents, the equipping character's Normal Attack SPD will increase by 10% while Normal, Charged, and Plunging Attack DMG will increase by 40% for 15s.
Note: The 2-pc set bonus is obviously a bad bonus for Itto but we're looking at the 4-pc bonus.

3) Retracing Bolide

2-Piece Bonus: Increases Shield Strength by 35%
4-Piece Bonus: Gain an additional 40% Normal and Charged Attack DMG while under the protection of a shield.
Note: This set grants you an additional 40% Normal and Charged Attack DMG when shielded. Crystallize can be unreliable so a consistent shielder is preferred, such as Zhongli.

4) Husk of Opulent Dreams (2) / Archaic Petra (2) / Emblem of Severed Fate (2) / Marechaussee Hunter (2)
