As Cavalry Captain of the Knights of Favonius, Genshin Impact’s Kaeya Alberich is highly respected by the people of Mondstadt, even with his Khaenri’ahn lineage. Kaeya is a four-star cryo sword wielder and is one of the first characters you meet in Genshin Impact. He’s known for being extremely charming and having a passion for sipping wine (we don’t blame him). In this Genshin Kaeya build guide, we take a look at his skills, weapons, artifacts, and more. So what are you waiting for? Cool it, and come along.

Come on, let’s get moving into our Genshin Impact Kaeya build.
Kaeya is a great unit for the early game and a versatile sub-DPS reaction enabler throughout. He has low energy recharge requirements, provides consistent cryo application, and is free to all new players, making him a reliable staple in your roster from the start. He excels most in freeze comps which make the most of his A4 Glacial Heart passive, first constellation (if you have it), and cryo resonance.
He doesn’t quite compare with some of the stronger, five-star cryo DPS units like Genshin Impact’s Ayaka and Genshin Impact’s Ganyu, who are two of the strongest damage dealers in the game, and he can also struggle to beat out his main competition – Genshin Impact’s Rosaria – when it comes to general attack and her synergy with melt teams.
As a sub-DPS, the rankings for his best weapons rely heavily on Kaeya’s artifacts and team comps. For a more general selection, here are our recommendations.
Mistsplitter Reforged is the best weapon for Kaeya‘s personal damage under the right circumstances, though it can be tricky to gain stacks for its passive without Chongyun. Freedom Sworn is another great option, especially in reverse melt teams due to its elemental mastery stat. It also offers a valuable team buff that comes in handy as long as Kaeya is the one triggering reactions. If you’re struggling to meet energy recharge requirements, a Skyward Blade is a good choice due to its high ER boost.
When it comes to four-star options, The Black Sword is a good crit stat stick, though its passive is relatively useless for sub-DPS Kaeya. Alternatively, Lion’s Roar is great for reverse-melt teams.
|Weapon||Effect||How to obtain|
|Mistsplitter Reforged (five-star)||Bonus effect: Crit damage
Skill: Gain a 12% elemental damage bonus for all elements and receive the might of the Mistsplitter’s Emblem. At stack levels 1/2/3, Mistsplitter’s Emblem provides a 8/16/28% elemental damage bonus for the wielder’s elemental type. The wielder gains one stack of Mistsplitter’s Emblem when a normal attack deals elemental damage, upon casting an elemental burst, and when their energy is less than 100%. Each stack’s duration is calculated independently
|Weapon banner (alongside Ayaka)|
|Freedom Sworn (five-star)||Bonus effect: Increases elemental mastery
Skill: Increases damage by 10%. When the wielder triggers an elemental reaction, they gain a Sigil of Rebellion. This effect can trigger once every 0.5 seconds, even when the character is not on the field. When they possess two sigils, both are consumed and all nearby party members obtain ‘Millennial Movement: Song of Resistance’ for 12 seconds, which increases normal, charged, and plunging attack damage by 16%, and attack by 20%. Once this effect triggers, you don’t gain another sigil for 20 seconds. Buffs of the same type don’t stack
|Skyward Blade (five-star)||Bonus effect: Increases energy recharge
Skill: Increases crit hit rate by 4%. The wielder gains Skypiercing Might when an elemental burst is used, this increases movement and attack speed by 10% and increases the damage of normal and charged attacks by 20% for 12 seconds
|The Black Sword (four-star)||Bonus effect: Crit rate
Skill: Increases damage dealt by normal and charged attacks by 20%. Also regenerates 60% of attack as HP when normal and charged attacks score a crit hit. This effect can occur once every five seconds
|Battle Pass reward|
|Favonius Sword (four-star)||Bonus effect: Increases attack
Skill: Crit hits have a 60% chance to generate a small amount of elemental particles, which regenerate six energy for the character. Can only occur once every 12 seconds
|Lion’s Roar (four-star)||Bonus effect: Increases attack
Skill: Increases damage against enemies affected by pyro or electro by 20%
In a freeze team, Blizzard Strayer is the best option for Kaeya without a doubt. It offers a nice boost to his cryo damage and pushes his crit rate even higher, which synergizes perfectly with the cryo resonance bonus.
If you’re hoping to put him in anything but a freeze team (i.e. reverse melt or a team that doesn’t rely on either melt or freeze), we recommend a full set of Emblem of Severed Fate, offering a boost to energy recharge and burst damage. Alternatively, combining two pieces of Blizzard Strayer with two pieces of Noblesse Oblige is a flexible option if you’re struggling to get a full set with decent stats.
|Artifact set||Effect||How to obtain|
|Blizzard Strayer||Two equipped: Cryo damage bonus
Four equipped: Increases Crit rate by 20% when attacking an enemy affected by cryo. If the enemy is frozen, it increases crit rate by an additional 20%
|Peak of Vindagnyr domain|
|Emblem of Severed Fate||Two equipped: Increases energy recharge
Four equipped: Increases elemental burst damage by 25% of energy recharge. You can obtain a maximum of 75% bonus damage in this way
|Momiji-Dyed Court domain|
|Noblesse Oblige||Two equipped: Increases elemental burst damage
Four equipped: Using an elemental burst increases all party members’ attack by 20% for 12 seconds. This effect cannot stack
|Clear Pool and Mountain Cavern domain|
Artifact stat recommendations
- Sands: Attack %
- Goblet: Cryo damage bonus
- Circlet: Crit damage
- Energy recharge to requirements
- Crit damage
- Crit rate (aim for around 45%)
Let’s take a look at what Kaeya can do with his kit, including combat talents and other benefits he provides off the field.
|Normal attack: Ceremonial Bladework||Normal: Perform five strikes.
Charged: Consume stamina to unleash two fast sword swings.
Plunging: Plunge from mid-air to deal AoE damage on impact with the ground
|Elemental skill: Frostgnaw||Unleashes a frigid blast, dealing cryo damage to opponents in front of Kaeya|
|Elemental burst: Glacial Waltz||Coalescing the frost in the air, Kaeya summons three icicles that revolve around him. These icicles will follow the active character around and deal cryo damage to opponents in their path for the ability’s duration|
|Cold-Blooded Strike (unlocked at ascension one)||Frostgnaw also regenerates HP to Kaeya equal to 15% of his attack|
|Glacial Heart (unlocked at ascension four)||Enemies frozen by Frostgnaw produce elemental particles|
|Hidden Strength (unlocked automatically)||Decreases sprinting stamina by 20% for the party|
You can level up Kaeya’s constellations if you receive him as a duplicate when making a wish. Here’s every bonus you receive as you level up.
|C1: Excellent Blood||Increases normal and charged attack critical hit rate against enemies affected by Cryo by 15%|
|C2: Never-Ending Performance||Increases the duration of Glacial Waltz by 2.5 seconds for a maximum of 15 seconds when it defeats an enemy|
|C3: Dance of Frost||Increases the level of Frostgnaw by three|

|C5: Frostbiting Embrace||Increases the level of Glacial Waltz by three|
|C6: Glacial Whirlwind||Summon an additional icicle when Glacial Waltz is used. It also regenerates 15 energy when cast|

While Kaeya can be an affordable main DPS, he benefits from a little help that can really boost his numbers. To get the best out of him, we recommend team comps with supports like Bennett or Chongyun, and an anemo grouper such as Kazuha or Sucrose to really get things going.
