Genshin Impact 5★ Dendro Sword Main DPS
Light of Foliar Incision is the closest fit on the game's own numbers: Alhaitham's kit multiplies Elemental Mastery, and a weapon is ranked here on whether its ascension stat and its passive act on that stat. Absolution, Xiphos' Moonlight and Mistsplitter Reforged come next. No playtested ranking has been imported for Alhaitham, so this is arithmetic over the kit data rather than a damage measurement.
Run Deepwood Memories on Alhaitham, with A Day Carved From Rising Winds and Blizzard Strayer behind it. Main stats are Elemental Mastery sands, Dendro DMG Bonus goblet, CRIT Rate / CRIT DMG circlet. Roll substats in the order CRIT Rate > CRIT DMG > Elemental Mastery > Energy Recharge.
Talent priority is Normal Attack > Elemental Skill > Elemental Burst. The Elemental Burst costs 70 energy, which is what an Energy Recharge target has to clear.
The strongest team is Alhaitham, Emilie, Xiangling and Bennett, built around Alhaitham: Dendro · Burning.
Normal Attack Performs up to 5 rapid strikes.
Charged Attack Consumes a certain amount of Stamina to unleash 2 rapid sword strikes.
Plunging Attack Plunges from mid-air to strike the ground below, damaging opponents along the path and dealing AoE DMG upon impact.

Rushes forward, dealing Dendro DMG to nearby opponents when the rush ends, causing a Chisel-Light Mirror to form. Holding this skill will cause it to behave differently.
Hold Enters Aiming Mode to adjust the direction of Alhaitham's rush attack.
Chisel-Light Mirror When this skill is unleashed, Alhaitham will generate 1 Chisel-Light Mirror. If there are no Mirrors at this time, he will generate 1 additional Mirror. Chisel-Light Mirrors will have the following properties: · When he possesses Chisel-Light Mirrors, Alhaitham's Normal, Charged, and Plunging Attacks will be converted to Dendro DMG. This cannot be overridden. · When attacks of the aforementioned kind hit opponents, the Chisel-Light Mirrors will unleash a Projection Attack that deals AoE Dendro DMG based on the number of Mirrors on the field. · A total of 3 Chisel-Light Mirrors can exist at once. · The Chisel-Light Mirrors will disappear one after the other over time, and will all disappear when Alhaitham leaves the field.

C1When a Projection Attack hits an opponent, Universality: An Elaboration on Form's CD is decreased by 1.2s. This effect can be triggered once every 1s.
C2When Alhaitham generates a Chisel-Light Mirror, his Elemental Mastery will be increased by 50 for 8 seconds, max 4 stacks. Each stack's duration is counted independently. This effect can be triggered even when the maximum number of Chisel-Light Mirrors has been reached.
C3Increases the Level of Universality: An Elaboration on Form by 3. Maximum upgrade level is 15.
C4When Particular Field: Fetters of Phenomena is unleashed, the following effects will become active based on the number of Chisel-Light Mirrors consumed and created this time around: · Each Mirror consumed will increase the Elemental Mastery of all other nearby party members by 30 for 15s. · Each Mirror generated will grant Alhaitham a 10% Dendro DMG Bonus for 15s.
The pre-existing duration of the aforementioned effects will be cleared if you use Particular Field: Fetters of Phenomena again while they are in effect.
C5Increases the Level of Particular Field: Fetters of Phenomena by 3. Maximum upgrade level is 15.
C6Alhaitham gains the following effects: · 2 seconds after Particular Field: Fetters of Phenomena is unleashed, he will generate 3 Chisel-Light Mirrors regardless of the number of mirrors consumed. · If Alhaitham generates Chisel-Light Mirrors when their numbers have already maxed out, his CRIT Rate and CRIT DMG will increase by 10% and 70% respectively for 6s. If this effect is triggered again during its initial duration, the duration remaining will be increased by 6s.
Alhaitham's outfit. "Don't bother the Scribe with trivialities... What do you think those soundproofers of his are for, anyway?" So observed an experienced staff member at the Temple of Silence.
Names, descriptions and art from the game data. Pick an outfit on the stage to see it full size.
Alhaitham is a 5-star Dendro character from Sumeru who uses a sword, released in version 3.4.
Alhaitham's abilities multiply Elemental Mastery. That is read from the scaling rows on the Elemental Skill and Burst, not from the ability description, so it reflects what the game actually multiplies rather than what the text mentions.
Light of Foliar Incision is the closest fit on the data: it is a 5-star sword with CRIT DMG as its ascension stat, and its passive acts on Elemental Mastery. Xiphos' Moonlight is the best 4-star alternative.
Deepwood Memories. Its 2-piece bonus is: Dendro DMG Bonus +15%. Its 4-piece bonus is: After Elemental Skills or Bursts hit opponents, the targets' Dendro RES will be decreased by 30% for 8s. This effect can be triggered even if the equipping character is not on the field.
Taking one talent from level 1 to 10 costs 1,652,500 Mora and 38× Philosophies of Ingenuity among other materials. The Materials tab lists every item per level.
Intuition: When a Projection Attack hits an opponent, Universality: An Elaboration on Form's CD is decreased by 1.2s. This effect can be triggered once every 1s.
