Is Kaeya Worth Using? Yes, Extremely Worth Investing In!

As one of the free starter characters, Kaeya is often overlooked by players rolling for flashy new 5-stars. However, at high investment, Kaeya‘s damage and Cryo application can rival premium options. With the right build and team, C0 Kaeya remains viable even in endgame Spiral Abyss. Read on as I analyze Kaeya‘s strengths in detail and showcase why our lovable Cavalier Captain is absolutely worth building!

Kaeya‘s Abilities – Smooth Cryo Application

Let‘s first go over Kaeya‘s innate abilities:

• Normal Attacks – Kaeya‘s normal attack multipliers are quite high for a 4-star character, with his maxed level 7 normal attack exceeding even some 5-star carries. His 4-hit combo has wide area of effect and good mobility in between swings, allowing him to incorporate dashes and repositioning smoothly during his attack rotation.

• Elemental Skill – Frostgnaw throws 2 icy rapiers that deal AOE Cryo damage. It generates 2-3 particles on a tap with only 4s CD, leading to high uptime and good energy refund. Holding consumes more stamina for added spear damage. Frostgnaw enables Kaeya to apply Cryo extremely quickly.

• Elemental Burst – Glacial Waltz summons 3 icy whirlwinds that persist on the field for 15s, dealing Cryo damage to any enemies inside their AOE. Against frozen enemies, Kaeya‘s Crit Rate is boosted by 20% while his burst is active. This burst is integral to enabling consistent Freeze and Melt reactions.

With spammable skills and no downtime between skill/burst uses, C0 Kaeya provides near constant Cryo application to trigger Melt and Frozen reactions. His particle generation from short E cooldown also helps fuel his 80 energy Burst.

Kaeya as Main DPS – Powerhouse Potential

While Kaeya isn‘t typically seen as a hypercarry option, he can definitely reach premium levels of damage at high investment.

Here is a chart comparing his damage ceiling to other 5-star Cryo DPS units:

Character	Normal Attack	Elemental Skill	Elemental Burst
C0 Kaeya	8k-12k	16k-20k	9k-11k per blade
C0 Ganyu	7k-9k	30k bloom	20k-35k AOE
C0 Ayaka	4k-8k	8k-10k tap	20k-30k N3C loop

As you can see, properly built C0 Kaeya can come extremely close to 5-star Cryo units in terms of his skill/burst damage. His normal attacks are weaker than Ganyu‘s Frostflake Arrows but surpass Ayaka‘s swinging attacks.

For weapons, I recommend Mistsplitter, Jade Cutter, Aquila Favonia or a Crit-focused Blackcliff for max damage. A 4-star option like Anemona can work at high refinements too. Prioritize Crit > ATK% > Cryo DMG for circlet, goblet and timepiece artifacts.

With 30%-40% Crit Rate from Blizzard Strayer against frozen foes, you can stack heavy Crit DMG to amplify his damage ceiling. Shoot for a minimum 70:140 Crit ratio, reaching 80:160+ if possible.

For teams, Kaeya needs consistent Freeze uptime to access the 40% Crit Rate buff. Pair him with Hydro applier Xingqiu or Mona + an Anemo grouper like Venti to swirl Cryo for Frozen AOE Blizzard Strayer procs.

Add a Cryo battery like Diona or Rosaria to funnel particles toward Kaeya‘s burst. Proper rotations and freezing will allow near 100% Frostgnaw and Glacial Waltz uptime to dish out huge Cryo damage!

Kaeya as Sub DPS – High-Impact Burst Bot

While C0 Kaeya can work as main DPS, he also excels as an off-field Sub DPS enabler, especially at lower investments.

The 4pc Emblem of Severed Fate artifact set is perfect for boosting his Elemental Burst damage during his 7s field time.

Prioritize Energy Recharge to spam Glacial Waltz off cooldown. Around 200% ER is comfortable with Cryo batteries like Rosaria/Diona. Favonius Sword also generates white particles on crits to boost his energy.

At talent level 8+, Kaeya‘s burst can deal 10k-15k damage per blade consistently off-field. Alongside swirled Cryo application every 2s, this sustained damage and enabling of Frozen reactions is extremely valuable.

Pair him with main DPS Ayaka or Ganyu for near 100% uptime on the 40% Crit Rate against frozen. This pushes their damage ceiling tremendously while stacking Crit DMG.

For Childe melee stance teams, Kaeya‘s burst applies Hydro onto frozen enemies for Childe‘s riptides to destroy in an AOE shatter-enabled nuke.

Kaeya as Support – Flexible Cryo Application

Even at low investment, Kaeya provides strong utility through:

• His E having only 4s CD for frequent Cryo application
• His Q lasting 15s and persisting off-field after casting
• Generating 4-5 energy particles per E cast
• Achieving 100% skill uptime with Sacrificial Sword

This consistent Cryo application makes Kaeya an excellent enabler for powerful Melt and Freeze comps. He can enable Pyro DPS like Diluc, Klee, and Yanfei to trigger Melt reactions reliably.

In Freeze teams, Kaeya gives the constant Cryo aura needed for Ayaka, Ganyu or Childe to perma-freeze lock enemies.

As a supporter, building ER, some ATK, and maxing his skill/burst is higher priority than stacking Crit. Equip Sacrificial or Favonius Sword for max energy refund.

Constellations – Good But Not Mandatory

Here‘s a quick rundown on Kaeya‘s constellations:

• C1 regenerates 15 energy after casting burst
• C2 extends Glacial Waltz duration to 18s
• C4 increases CRIT Rate by 15% against Cryo-affected enemies
• C6 increases Frostgnaw crit rate by 15% if hitting only 1 enemy

Kaeya‘s C1 energy refund and C4 extra Crit are his most valuable traits, providing welcome boosts. However, high constellation Kaeya remains rare as a starter character.

The good news is C0 Kaeya still performs excellently. So while nice to have, constellations are absolutely not critical to make him viable. Consider them a bonus rather than a requirement.

Constant Hydro application + Kaeya‘s Cryo enable frozen enemies for 40% free Crit Rate from Blizzard Strayer. Venti/Kazuha swirls his Cryo for AOE damage. Flex slots add utility based on needs – particles, healing, buffs, etc.

Melt Comps

• Kaeya, Xiangling, Bennett, Anemo unit (Sucrose, Venti, Kazuha)

Kaeya‘s Cryo enables Xiangling Pyro aura for forward Melt. Sucrose/Kazuha boost EM for amplified Melt damage. Bennett provides healing, buffs, and energy to fund bursts.

Superconduct

• Kaeya, Electro applier (Fischl, Raiden), Cryo battery (Rosaria, Diona)

Raiden/Fischl trigger Superconduct from Kaeya‘s Cryo for 40% Physical RES shred. Add a 2nd Cryo like Rosaria for energy particles to fuel Kaeya‘s Burst.

Permafreeze

• Kaeya, Chongyun, Xingqiu, Flex (Anemo, shielder, healer)

Chongyun‘s skill converts Kaeya‘s Normal Attacks to Cryo. Combined with Xingqiu swords, this freeze locks enemies permanently. Flexible 4th slot.

There are many powerful Kaeya team options – pick based on your roster‘s needs and strong synergies!

Spiral Abyss Viability

Despite being only a 4-star character, Kaeya‘s damage and enabling utility secure him spots on many top meta Spiral Abyss comps, including:

• Enabler for Ayaka/Ganyu permafreeze teams
• Battery/sub-DPS for Eula/Raiden Superconduct teams
• Melt burst support for Xiangling reverse melt teams
• Chongyun duo for melee freeze comps

His ability to enable reactions, generate energy, and deal off-field damage provides utility across multiple top-tier team archetypes, making him a secret 5-star powerhouse.

Players consistently 36-star clear endgame Spiral Abyss using Kaeya as main DPS, showcasing his power when fully invested in.

Even low-investment support Kaeya boosts other powerful 5-star main DPS like Ayaka and Hu Tao through freezing, Superconduct uptime, and energy generation.

Popularity and Lore

As an early Mondstadt character integral to the Archon quests, Kaeya has an intriguing backstory that remains mysterious. Some key lore points:

• Hails from the destroyed nation of Khaenri‘ah, making him over 500 years old
• Acts as a spy leaking intel back to Khaenri‘ah
• Has a hidden eyepatch and dormant elemental powers…
• Adopted as a noble by Crepus to integrate Khaenri‘ah into Mondstadt politics

This layered lore and cool, snarky personality contribute to Kaeya‘s popularity as a husbando character.

Many fans actively main and triple crown their Kaeya, despite his rarity. r/KaeyaMains has over 30k members – an impressive figure for a low-rarity character!

Conclusion – Wholeheartedly Recommended

In summary, Kaeya is absolutely worth investing in and using for a variety of team roles. As a free starter character, he offers immense utility and even main DPS potential at low cost.

At high investment with optimal rotations and freezing comps, C0 Kaeya can unleash devastating Frostgnaw and Glacial Waltz damage rivaling premium 5-stars.

His spammable skills, energy refund, and enabling make him an excellent quickswap Sub DPS or Support as well.

So don‘t sleep on our charming Cavalry Captain. Give Kaeya a spot on your roster – he may just carry your teams through the Spiral Abyss! Let me know if you have any other questions.
