Alhaitham

Alhaitham is a playable Dendro character in Genshin Impact.

Alhaitham is a member of the Haravatat of the Sumeru Akademiya and the Akademiya's Scribe, responsible for documenting their findings and drafting ordinances. Despite his brilliance, people within the Akademiya are perplexed by Alhaitham due to his unwillingness to aspire for higher office in spite of his egocentricity, and many have been at odds with him for his uncompromising view on rationality and the truth.

	Universality: An Elaboration on Form	Elemental Skill
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 kinds 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. When a Projection Attack hits at least one enemy, it generates 1 Elemental Particle. This particle generation has a cooldown of 1.5 seconds. Projection Attacks individually snapshot upon starting their animation. A Plunging Attack can be performed immediately after holding this skill, regardless of Alhaitham's altitude. Passive Effects Passive Talent 1, Four-Causal Correction: "When Alhaitham's Charged or Plunging Attacks hit opponents, they will generate 1 Chisel-Light Mirror. This effect can be triggered once every 12s." Passive Talent 2, Mysteries Laid Bare: "Each point of Alhaitham's Elemental Mastery will increase the DMG dealt by Projection Attacks and Particular Field: Fetters of Phenomena by 0.1%. The maximum DMG increase this way for both these abilities is 100%." Constellation Effects Constellation Level 1, Intuition: "When a Projection Attack hits an opponent, Universality: An Elaboration on Form's CD is decreased by 1.2s.

Each stack's duration is counted independently. This effect can be triggered even when the maximum number of Chisel-Light Mirrors has been reached." Constellation Level 3, Negation: Increases this talent's level by 3, up to a maximum of 15. Constellation Level 6, Structuration: "Alhaitham 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.

	Particular Field: Fetters of Phenomena	Elemental Burst
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. DMG dealt by this skill will snapshot Alhaitham's stats on cast and will not be affected by changes in his stats that occur afterwards. If the player switches to a different character and back to Alhaitham within 2s after using this skill, Alhaitham will still be able to regenerate Mirrors. However, if the player fails to switch back within 2s, the Mirrors will not be gained. Passive Effects Passive Talent 2, Mysteries Laid Bare: "Each point of Alhaitham's Elemental Mastery will increase the DMG dealt by Projection Attacks and Particular Field: Fetters of Phenomena by 0.1%. The maximum DMG increase this way for both these abilities is 100%." Constellation Effects Constellation Level 4, Elucidation: After casting this talent, grants nearby party members 30 Elemental Mastery per Chisel-Light Mirror consumed and Alhaitham 10% Dendro DMG Bonus per Mirror generated. These buffs last for 15 seconds after the Mirrors are consumed or generated. Constellation Level 5, Sagacity: Increases this talent's level by 3, up to a maximum of 15. Constellation Level 6, Structuration: Changes the number of Chisel-Light Mirrors generated after casting this talent to always be 3, regardless of how many were consumed. Additionally, generating Chisel-Light Mirrors when 3 already exist will now increase Alhaitham's CRIT Rate and CRIT DMG by 10% and 70% respectively for 6s.
