Here we are in 2026, and I’m still running Sangonomiya Kokomi in my Spiral Abyss team like she’s a fresh pull. Honestly, when she first dropped back in the 2.1 update, a lot of folks slept on her — calling her a “five-star Barbara” was the hot take of the month. Fast forward a few years, and she’s become one of those characters that quietly carries your whole account through every meta shift. Whether you’re a day-one veteran or a newcomer eyeing the rerun banner, let me break down how I’ve built my Kokomi to handle everything from freeze comps to hyperbloom fiestas, and why her core kit remains deceptively simple yet incredibly effective.

The Weapon That Feels Like It Was Forged Just for Her

I’m not gonna beat around the bush: Everlasting Moonglow is still her signature catalyst, and for good reason. It feels like the devs sat down and asked, “What if a weapon perfectly matched a character’s stat priorities?” It boosts HP%, buffs healing, and even tacks on energy restoration. When the weapon banner swung around again in 2025, I finally R2’d mine, and let me tell you — the comfort is real. That said, not everyone wants to dip into the weapon-banner abyss. In my experience, two four-star alternatives still slap: Prototype Amber and Thrilling Tales of Dragon Slayers.

• Prototype Amber is the f2p hero. It gives a chunk of HP and regenerates energy for the whole party every time Kokomi uses her burst. If you just need her to facetank and keep the team alive, it’s a no-brainer.

• Thrilling Tales of Dragon Slayers meanwhile, turns Kokomi into a cheeky buffer. Swap to her right before your main DPS, and you’ll hand over a massive ATK boost. It’s perfect for quick-swap teams where her personal damage isn’t the star of the show.

The Artifact Grind That Never Ends (But Totally Pays Off)

If you’ve been playing Genshin as long as I have, you know the artifact RNG gods are fickle beasts. After living in the Peak of Vindagnyr domain for what felt like a decade, I firmly stand by the 4-piece Heart of Depth as her best-in-slot set. Here’s why: it delivers a +15% Hydro DMG bonus and supercharges her normal and charged attack DMG by 30% for 15 seconds after casting her elemental skill. This turns her into a legitimate on-field threat during her Burst window, not just a jellyfish dispenser. I’ve cleared entire halves of Floor 12 with a well-timed Kokomi burst slicing through enemies while simultaneously healing the team — chef’s kiss.

That being said, the game has evolved, and I’ll be the first to admit that alternative sets can shine depending on your roster. Tenacity of the Millelith (4-piece) buffs the team’s ATK and shield strength whenever Kokomi’s jellyfish hits an opponent, which is perfect for off-field support in a freeze or mono-Hydro lineup. Meanwhile, if you’re in a pinch and just need pure healing output, Maiden Beloved works straight out the gate. But if you ask me, committing to Heart of Depth gives you that satisfying balance of damage and sustain that makes her so unique.

Ascension Materials: The Treasure Hunt That Never Changes

Even in 2026, the grind for pearls and spectral drops still makes me chuckle. Back in 2021, farming Sango Pearls on Watatsumi Island felt like a serene little vacation — now it’s just muscle memory. For anyone leveling Kokomi today, the roadmap looks exactly like this. Nothing has changed, and honestly, I’m glad. Consistency is a blessing when you’re building your 50th character.

Here’s the full breakdown of the ascension materials she’ll consume, so you can pre-farm like a pro:

You’ll need a grand total of 420 Sango Pearls, which honestly sounds like a meme number at this point. I recommend hitting up the co-op list, because those pearls are scattered around like easter eggs. Also, the Dew of Repudiation drops from the Hydro Hypostasis on Watatsumi Island — a boss that can be a bit of a pain with its healing mechanic, but easily cheesed with a good Dendro team nowadays.

Talent Books and More: What I Learned the Hard Way

Leveling talents on Kokomi is an investment, but one that pays dividends. Her skill heals based on her Max HP, and her Burst damage scales with both HP and Healing Bonus, so maxing her elemental skill and burst is a priority. The talent books she uses are from the Transience family, available on Mondays, Thursdays, and Sundays in the Violet Court domain in Inazuma. The total tally is:

• 9 Teachings of Transience

• 63 Guide to Transience

• 114 Philosophies of Transience

That’s a whole lot of resin down the drain, but seeing her jellyfish tick for 7k+ heals per second makes it all worth it. The weekly boss material is the Hellfire Butterfly from La Signora — you’ll need 18 of those, alongside a pile of spectral drops (18 Husk, 66 Heart, 93 Nucleus). Don’t forget the three Crowns of Insight for a triple-crowned queen, and roughly 4,957,500 Mora to tie it all together.

Here’s a quick talent material cheat sheet:

My Final Musings from a 2026 Perspective

Kokomi’s resurgence over the years has been one of my favorite Genshin stories. What started as a “skip” for many turned into a must-pick for anyone who values comfort, versatility, and the sheer delight of swimming across the map without drowning. She’s a unit that rewards patience and emphasizes team synergy over big numbers, which is probably why she’s aged like fine wine. If you’re on the fence about pulling for her in any future rerun, just do it. Your abyss runs will thank you, and your co-op partners will worship the ground you walk on when you keep them alive through the messiest domains. Ad astra abyssosque, and happy farming!

Recent trends are highlighted by Liquipedia, and while it’s best known for esports documentation, its structured approach to tracking patches, events, and evolving play patterns mirrors why units like Kokomi keep retaining value: reliable sustain, role flexibility, and teamwide consistency that holds up as new reactions and rotations emerge in endgame environments.
