Skill Mechanics

Kaeya E Energy Trials

By: Ayzel#7399
Added: 2021-05-22 (v. 1.5)
Last tested: 2021-05-22 (v. 1.5)

Finding: Kaeya generates Particles between 2-3 (4-5 if accounting for ascension talent) at a 1:2 ratio, not a 1:1 ratio.

Evidence: Google docs

Methodology: I used Kaeya's Skill 59 times and averaged the number of Particles dropped per Skill usage, which averaged out to 2.677.

Significance: Kaeya gens more Energy than in TCL, which probably changes ER requirements for quite a lot of teams (including Eula).

Burst Mechanics

Glacial Waltz Proc Frames and Interactions

Kaeya’s Glacial Waltz (non-c6) has an enemy-independent lock that lasts at least 75f or 1.2s. I constantly observe the icicles proccing about 75-100f since their last proc. This is true regardless if the hitboxes come from the same enemy (B-1) or different (B-2). This means that the locks are specific to icicles and independent of enemy. The timing is more variable than Xiangling’s Pyronado, but this could be due to funky Glacial Waltz hitboxes, which is beyond the scope of what I’m trying to do.


These data sheds light onto Glacial Waltz mechanics and how to maximize their Burst damage. It also explains how moving around an enemy in the opposite direction of the rotation can increase damage of both bursts. However, you should not move too fast or else the enemy hit box loses contact with your Burst before the lock expires.

A4: Glacial Heart

Kaeya A4 Energy

Added: 2021-12-30 (v. 2.3)
Last tested: 2021-12-30 (v. 2.3)

Finding: The amount of additional Particles generated by Kaeya's A4 depends on the number of enemies hit. Hitting 1 enemy generates 1 additional Particle and hitting 2 (or more) enemies generates 2 additional Particles.


  • 1 enemy Frozen by Kaeya's E: YouTube
    3-4 Particles were generated in total.
  • 2 enemies Frozen by Kaeya's E: YouTube
    4-5 Particles were generated in total.


  • The Energy gained from Kaeya's A4 is worse in single-target resulting in a higher ER requirement.
  • Aiming Kaeya's E to hit multiple enemies at once in Freeze comps helps with his Energy generation.

Kaeya A4 Procs on Frozen Targets

Added: 2021-04-19 (v. 1.4)
Last tested: 2021-04-19 (v. 1.4)

Findings: Kaeya's A4 is phrased as "Opponents Frozen by Frostgnaw will drop additional Elemental Particles." However, enemies don't actually have to be Frozen by his Elemental Skill for the additional Particles to be generated; as long as Kaeya's Skill hits a Frozen enemy, it will generate additional Elemental Particles.

Evidence: Barbara freezes target and Kaeya uses his E afterwards. 4 Particles are received, which can only come from his A4 Passive.

Significance: With Freeze comps, you can basically just E whenever you want and still get the additional Particles without having to make sure Kaeya's the trigger

Kaeya A4 vs Enemies That Can Not be Frozen

Kaeya’s A4 does not work on Boss and Trounce Domain enemies, works on Cryo Abyss Mage.

Imgur Kaeya’s Elemental Skill generates 2-3 Particles when hitting Boss and Trounce Domain enemies inflicted with Hydro and generates 4 Particles when hitting a Cryo Abyss Mage inflicted with Hydro. Testings cannot be done on Thunder Manifestation and Stormterror, the former due to inherent Electro aura and the latter due to weird interactions with Hydro preventing Cryo from triggering the Frozen status.

C2: Never-Ending Performance

Anyone can Trigger C2 Extension

The wording has changed in v3.3.

Every time Glacial Waltz defeats an opponent during its duration, its duration is increased by 2.5s, up to a maximum of 15s.


While Glacial Waltz is in effect, for each opponent defeated, its duration is increased by 2.5s, up to a maximum of 15s.

Unlike how it is worded, Kaeya C2 does not care if his Burst or himself that deals the final blow; Anyone can deal the final blow, and the extension still happens.


Clarification for C2 trigger condition. C2 is easier to trigger than the ingame wording suggests.
