Kaeya Alberich’s greatest personal trait is the inherent mystique behind his motives, which tends to present itself rather prominently in his daily duties as Cavalry Captain of the Knights of Favonius. Interestingly enough, this same mystique has lead to the personal distrust of some who can only assume that there’s always a deeper meaning behind his actions.

“Mystique” is the name of the game for his combat toolkit as well, with his abilities being spread somewhat thinner than most in exchange for “lightweight” versatility.

In this guide, we’ll go over Kaeya’s abilities, what he’s naturally set up to be able to do, and general build advice for how to build him out to suit your intent and purpose.

High-Level Overview


  • He possesses incredible uptime on his Elemental Burst due to natural Energy Recharge passive abilities, and has the second highest natural ability uptime on it independent of his equipment kit in the game (surpassed only by Bennett).
  • Moderately high DEF stat by default, coupled with Constellation 4 make him relatively difficult to bring down in a running battle.


  • Fairly low ATK stat for a melee character is compensated for by the CRIT Rate buff he receives at Constellation 1. Blizzard Strayer 4-piece set can augment this considerably further.
  • Ascension 4 passive ability gives him natural health regeneration off his Elemental Skill, although it’s ATK-dependent.


  • Outside of his Cryo Skill/Burst, Kaeya brings very little natural combat power to fights. Arguably a “Cryo Bot” who’s rarely in play when his abilities are on cooldown.
  • Has to be built fairly hard into ATK for most of his kit to begin to truly shine, but offers a greatly reduced return-on-investment for farm from doing so based on what percentages his Skill/Burst top out at. (when compared to other characters)

Combat Disposition

Our analysis on Kaeya showed that while his kit is split between several different focus areas, he is most strongly geared towards cryo elemental damage, in both static and dynamic formats. This conclusion was reached by considering the following points:

  1. His Ascension bonus attribute is Energy Recharge %., fueling his Elemental Burst considerably.
  2. His 4th Ascension passive ability gives him additional Elemental Particles back off of using his Elemental Skill.
  3. Constellation 2 increases the duration of his Elemental Burst.
  4. Constellation 6 further increases the damage potential and Energy gainback from his Elemental Burst.

Kaeya’s build is heavily dependent upon what scope of damage you want him to provide in the team composition he’s in. If he is going to be dealing predominantly independent Cryo DMG, if he’s going to be multipurpose – or if you’re not sure – then a build focused around ATK and Energy Recharge, with a lesser emphasis in CRIT Rate and CRIT DMG is ideal. If Kaeya is a setup or culminating elemental effect in combo reactions for the majority of his usage, focusing on ATK and Elemental Mastery with a lesser branching into Energy Recharge may give you the best results.

Core mechanics that Kaeya can be built around include:

  1. Cryo DMG builds, using weapons such as the Iron Sting or the Cool Steel, and artifact set bonuses such as the Noblesse Oblige or the Blizzard Strayer.
  2. Physical DMG Builds, using weapons such as The Black Sword, the Prototype Rancor or the Harbinger of Dawn, and artifact set bonuses such as the Bloodstained Chivalry or Berserker.

Kaeya’s a more difficult character to classify because his abilities, passives, and Constellation Levels are divided between three different areas of thought (Energy Recharge, Attacks/CRIT on Attacks, and Cryo DMG), and subsequently cause him to be slightly weaker all-around; requiring more farm towards any one area than most characters to achieve the same level of combat viability as other, more pointed characters. While it can be said that this could be considered as a strength in a way, the author would consider it to be an inherent obstacle to overcome in all but the early-to-mid game.

Our Personal Take

What Kaeya’s extremely good for is being a character who can easily, readily get the Cryo effect into play at almost any point, on-demand. Serious Cryo DMG, however? Well, you might have to take a rain check on that piece depending on what you’re able to farm. That being said, he offers constant access to dynamic Cryo DMG that’s really easy to elemental combo off of – and this trait is viable at all points of the game.

His lore in both the game as well as in the official manga is quite interesting. The circumstances around his adoption into Diluc’s household, his subtle connections to the Treasure Hoarders, and his reasons for remaining with the Knights of Favonius – his life has a lot of story to tell, for those willing to listen.

Kaeya has a moderate following in terms of the female playerbase for Genshin Impact, alongside Diluc, Tartaglia, and Zhongli. While the reasons for this are as varied as the people behind them, it’s great to know that his addition into the game is appreciated for reasons beyond simply the gameplay.

The English Voice Actor (VA) for Kaeya, Josey Montana McCoy, is the cousin of one of the author’s longtime friends, and it’s pretty awesome to see him enjoying the success with the role in Genshin Impact that he holds.
