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.

Character Description

Alhaitham performs a thrust when his Elemental Skill is used, generating Chisel-Light Mirrors and causing his Normal, Charged, and Plunging Attacks to be temporarily converted to Dendro DMG. When Chisel-Light Mirrors are present, these attacks will also activate Projection Attacks when they hit opponents, with the power of said Projection Attacks being determined by the number of Mirrors present.
Alhaitham's Elemental Burst will deal multiple instances of Dendro DMG to opponents in quick succession. If Chisel-Light Mirrors are present, they will all be consumed to increase the number of DMG instances. After this ability is unleashed, new Chisel-Light Mirrors will be created based on the number of said Mirrors consumed.
