- Ascension stat: Dendro DMG Bonus
The current scribe of the Sumeru Akademiya, a man endowed with extraordinary intelligence and talent. He lives free — free from the searching eyes of ordinary people, anyway.
What it costs to finish this character
Ascension alone: 760 resin (boss drops only) · talents alone: 590 resin.
Talent domain: Ingenuity, open Tuesday, Friday, Sunday.
A Crown of Insight is needed for the tenth level of each talent, and crowns are not farmable at any resin price — they come from events.
Materials and mora above are exact, straight from the game’s own tables. The resin figure and the day count divide by an average drop per run, which the game does not publish — they are a community-measured mean, not a promise.

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.

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.

·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.

Weapons and artifacts
UNSURE This is not a tier list and not community guidance — this product has neither. It is a mechanical shortlist, and the rule is printed so you can check it: Swords of 4★ and above whose secondary stat is one this character’s ascension stat scales with, ordered by base attack at level 90. Weapon passives are not weighed, because a passive is an effect and not a number.

To turn this into a real recommendation section, add a build dataset — per character, the weapons and sets a community source actually recommends, with the rotation each assumes. Nothing in the game’s published data contains that judgement, and a ranking invented here would be indistinguishable from a researched one, which is why there is not one.
