Kaeya's flexibility makes him valuable in many team setups, whether as a primary source of damage, a Cryo applicator for reactions, or a burst support providing supplementary damage and crowd control. Adjust his build according to your team's needs and the enemies you're facing.
Kaeya, the Cavalry Captain of the Knights of Favonius in "Genshin Impact," is a versatile Cryo sword user who can fit into various team roles, from main DPS to support.
Here's how you might build him for optimal performance:
Suggested Weapons 
•Aquila Favonia: Offers high base attack and its passive increases ATK, heals the user, and deals additional damage when Kaeya takes damage, synergizing well with his need to be in combat.
•The Black Sword: Increases DMG dealt by Normal and Charged Attacks, and its CRIT Rate increase from the passive can be beneficial for Kaeya's DPS.
•Skyward Blade: Provides Energy Recharge, which helps with uptime on his Elemental Burst, along with increasing CRIT Rate.
•Favonius Sword: If you're focusing on him as a support or need more energy for your team, this sword generates energy particles when you land a CRIT hit.
•Mistsplitter Reforged: Although this is often better on other characters due to its elemental DMG bonus, it's still a strong option due to its high base ATK and CRIT DMG.
Best Artifact Sets for Kaeya
•4-piece Blizzard Strayer: Ideal for a Cryo DPS build, especially in teams where you can freeze enemies consistently. The set provides +15% Cryo DMG Bonus with 2 pieces, and with 4 pieces, it increases CRIT Rate when attacking Cryo-affected or frozen enemies.
•2-piece Blizzard Strayer + 2-piece Gladiator's Finale or Noblesse Oblige: A mix for increasing both Cryo DMG and ATK% or Elemental Burst DMG, offering versatility.
•4-piece Cryo Resonance Team (with another Cryo User): If you're running double Cryo for resonance, which increases CRIT Rate against Cryo-affected or frozen enemies, you might focus less on CRIT Rate in artifacts.
Artifact Stats Priority
•Sands: ATK% or Energy Recharge if using him as a burst support.
•Goblet: Cryo DMG Bonus
•Circlet: CRIT Rate or CRIT DMG (Balance these based on your total CRIT stats)
Sub-stats to look for
•CRIT Rate
•CRIT DMG
•ATK%
•Energy Recharge (especially if his burst uptime is crucial)
Talent Prioritization
•Normal Attack - Ceremonial Bladework - If he's your main DPS, this should be leveled first for basic attack damage.
•Elemental Burst - Glacial Waltz - Provides continuous Cryo application and damage around him, crucial for both DPS and support roles.
•Elemental Skill - Frostgnaw - Important for Cryo application and energy generation, but secondary to his Burst if he's not the main damage dealer.
Team Composition
•Freeze Team: Pair with Hydro users like Xingqiu or Mona for permafreeze, maximizing his CRIT rate with Blizzard Strayer.
•Superconduct Team: With an Electro character like Fischl or Raiden Shogun for physical damage builds, reducing enemy physical resistance.
•Support: Characters like Diona for shields, healing, and Cryo resonance, or Venti for crowd control and elemental absorption.
Playstyle Tips
•Burst Rotations: Use his Elemental Burst in tandem with other characters' abilities to maintain Cryo application for reactions.
•Skill Usage: His Elemental Skill has a short cooldown, use it to apply Cryo or to generate energy for his Burst.
•Positioning: Kaeya can be quite versatile; in a DPS role, stay close to apply Cryo with normal attacks, but in support, you might want to switch him in for skills and bursts then swap out.
