Overview
Alhaitham generates Chisel-Light Mirrors from skill and burst for enhanced attacks. Mirrors consume on hit but regenerate through skill/burst. He scales with EM for Spread and CRIT for personal damage. Quickswap between Alhaitham and Fischl for optimal Aggravate uptime.
How to Play
Use skill and burst to generate mirrors, then normal attack combo to consume mirrors for Dendro damage. Reapply skill when mirrors deplete. Stay on-field during mirror windows, swap to Fischl when mirrors are gone. Nahida provides Dendro RES shred and EM buff.
Optimal Rotation
Nahida Skill/Burst, Fischl Skill, Kazuha Swirl, Alhaitham Skill, Alhaitham Burst, Alhaitham NA combo, Fischl Burst, swap back to Alhaitham when skill is ready.
F2P Options
Iron Sting or Sapwood Blade are excellent F2P swords. Gilded Dreams 4pc with EM sands. C0 Alhaitham with Fischl and free Nahida (if you have her) is one of the strongest F2P-friendly teams.
Common Mistakes
Attacking without mirrors wastes damage potential. Building pure CRIT without EM loses Spread damage. Not running Fischl, Oz is essential for Aggravate procs. Using Deepwood on Alhaitham when Nahida already wears it, Gilded Dreams is better.
