Alhaitham
Who is Alhaitham?
Alhaitham is a 5★ Dendro Sword character and the Scribe of the Sumeru Akademiya. He is an S-tier on-field Dendro DPS whose Chisel-Light Mirrors convert his attacks to Dendro and add AoE Projection Attacks, enabling constant Dendro application for Quicken/Aggravate, Hyperbloom, and Bloom teams while also dealing strong personal damage. He is a self-sufficient carry at C0. Source: https://keqingmains.com/q/alhaitham-quickguide/
Kit Summary
With Chisel-Light Mirrors active, Alhaitham's strikes deal Dendro and trigger Projection Attacks — his main damage source.
An Elaboration on Form): Dash that generates Chisel-Light Mirrors and Dendro Projection Attacks. Using the Skill with mirrors already active yields 1 new Mirror instead of 2.
Fetters of Phenomena): Consumes all active Mirrors for a large AoE Dendro nuke, then automatically reloads 3 Mirrors after ~2 seconds.
A Charged or Plunging Attack hit generates 1 Mirror (12s cooldown).
3; each Mirror lasts 4s independently and is lost on swap.
Build Guide
🔮 Best Relic / Echo Set
4pc Gilded Dreams (general BiS when a teammate holds Deepwood Memories). 4pc Marechaussee Hunter (BiS in Furina or Nilou Bloom teams). 4pc Deepwood Memories (use when no other Deepwood holder in the team). 2pc mixed or 4pc Golden Troupe are comparable with excellent substats.

⚔ Best Light Cone / Weapon
Light of Foliar Incision (BiS single-target, EM-scaling). Primordial Jade Cutter (best multi-target). Mistsplitter Reforged / Haran Geppaku Futsu (top CRIT swords). Best 4★: Wolf-Fang (approximately Mistsplitter at R5). Best F2P: Iron Sting (EM synergy). Source: https://keqingmains.com/q/alhaitham-quickguide/
📊 Substats Priority
👥 Best Teams
Quicken / Aggravate (recommended): Alhaitham + Nahida + Fischl or Yae + Kazuha or Zhongli
Hyperbloom: Alhaitham + Hydro + Electro (Kuki/Raiden)
Nilou Bloom: Alhaitham + Nilou + Hydro + Hydro or Dendro (4pc Marechaussee recommended)
F2P Verdict
Fully viable at C0. Iron Sting (craftable, EM) is his best F2P weapon; Wolf-Fang (Battle Pass) is an excellent 4★ alternative.
Build 200–300 EM alongside CRIT; ER requirement ranges from ~105–140% with Nahida + Electro partners to up to ~220% if running solo Dendro.
