The Sumeru Akademiya Scribe Alhaitham has a rerun banner on Genshin Impact Version 3.7! Read on for his skills, talents, materials, and more.

Alhaitham Details

“The current scribe of the Sumeru Akademiya. This title may sound very impressive, but it's really because the Akademiya has a culture of using official titles to inflate one's ego.”

“Admonishing Instruction” Alhaitham is a 5-star Dendro Sword character that became playable on Genshin Impact Version 3.4. His Ascension Stat is Dendro DMG%, earning up to 28.8% on max Ascension. His birthday is February 11.

Alhaitham's constellation is named Vultur Volans according to the official reveal. He holds the position of Sumeru Akademiya Scribe, as those who are kept up to speed with the Archon Quest may already be aware.

He is meant to be the main damage source in a party, and if you need some guidance on what to equip him with, you can check out our Alhaitham build guide. If you haven't decided yet whether he's worth the Primogems or not, let us help you figure it out: Should You Pull For Alhaitham?

  • Performs up to 5 rapid strikes.

Elemental Skill: Universality: An Elaboration on Form

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.

“Truth inherently exists amidst uncertainty. Even the greatest of scholars are not immune to error.”

The Rush Attack damage deals (193.6% ATK + 154.88% Elemental Mastery) at Talent level 1, (348.48% ATK + 263.3% Elemental Mastery) at Talent level 10, and (411.4% ATK + 329.12% Elemental Mastery) at Talent level 13.

The projection itself deals damage, depending on how many Chisel-Light Mirrors he has.

  • 1 Mirror Projection Attack DMG
    • lv1: 67.2% ATK + 134.4% Elemental Mastery
    • lv10: 120.96% ATK + 241.92% Elemental Mastery

Each of the stacks falls off after 4 seconds. The cooldown of this skill is 18 seconds.

Elemental Burst: Particular Field: Fetters of Phenomena

Creates a Particular Binding Field and deals multiple instances of AoE Dendro DMG.

If Chisel-Light Mirrors exist when this ability is unleashed, all such Mirrors will be consumed and increase the number of DMG instances dealt.

2s after this ability is unleashed, if 0/1/2/3 Mirrors were consumed, Alhaitham will generate 3/2/1/0 new Mirrors in turn.

“If a researcher makes wisdom their goal, then they should be prepared to make an enemy of every word they read. Only then can they avoid bias.”

Each instance of damage deals (121.6% ATK + 97.28% Elemental Mastery) at level 1, (218.88% ATK + 175.1% Elemental Mastery) at level 10, and (258.4% ATK + 206.72% Elemental Mastery).

If no Mirrors are consumed, the Elemental Burst will deal 4 instances of damage. Each Mirror consumed will add 2 instances each, up to a maximum of 10 total.

The cooldown for the Burst is 18 seconds, and it costs 70 Energy to cast.

Other Alhaitham Details

Alhaitham's special dish is called Ideal Circumstance, made by cooking Shahrizabz Meat Stew with him.

  • Effect: Restores 40% of Max HP and an additional 2,350 HP to the selected character.
  • Description: Alhaitham’s specialty. A dish through the fusion of vegetables and meat prepared in a patterned frying pan. Improvements were made to the recipe, making it taste quite different from the original dish. The words on the food mean “contemplation.” In the words of the creator: “Ideally, everyone should be capable of contemplation, but practically, it doesn’t seem very possible.”

His outfit is aptly named The Rational.

  • Description: Alhaitham’s outfit. “Don’t bother the Scribe with trivialities… What do you think his headphones are for, anyway?” — so observed an experienced staff member at the Temple of Silence.

He is voiced by Nazeeh Tarsha on the English voiceover, while Umehara Yuuichirou provides his Japanese voice.

HoYoverse Introduction

“I can't deny that he's very smart. However, it's a shame that a man of such talent only pays attention to the truth itself and not to the people around him. Or perhaps this is due to an extraordinary sense of individualism, which causes a lot of problems. For example, he doesn't seem to respect his seniors… Of course, I'm not referring to myself specifically.”
