Plan a team around these talents

Read the Elemental Skill and Burst separately from passive talents and Constellations. A listed Constellation effect should only be included in your plan when unlocked.

GetCheatBeacon's practical checklist for Alhaitham:

  • Which talent needs field time, and which can contribute after switching characters?
  • What Energy, cooldown or unlock requirements are listed for the effect you want?
  • Which teammate covers the gap in your current party?
  • Test a rotation you can repeat before investing further. This reference is not a ranked artifact or weapon build.
