This Genshin Impact Crystal Core farming guide breaks down exactly where to find them, the best daily route across every region from Mondstadt to Snezhnaya, plus a few tips to make catching Crystalflies faster and less frustrating.

What are Crystal Cores
Crystal Cores go into five different recipes: the Adepti Seeker's Stove, Condensed Resin, Dendrocide Potion, Frostshield Potion, and Windbarrier Potion. You get them from Crystalflies, those glowing, butterfly-looking creatures scattered around Teyvat. They're not the same as the regular decorative butterflies you'll run into either, those don't drop anything when caught.
Each region has its own elemental variant of Crystalfly. Though catching any of them yields the same Crystal Core. As of Version 7.0, that includes:
- Anemo Crystalfly (Mondstadt)
- Cryo Crystalfly (Dragonspine)
- Geo Crystalfly (Liyue)
- Electro Crystalfly (Inazuma)
- Dendro Crystalfly (Sumeru)
- Hydro Crystalfly (Fontaine)
- Pyro Crystalfly (Natlan)
Nod-Krai breaks the pattern slightly, using Moonglow Fireflies instead of a standard elemental Crystalfly, though they still yield Crystal Cores the same way.
Crystalflies respawn on a set timer rather than staying put permanently, so once you clear an area out, it'll take some time before that same spot has fresh ones to catch again.
Genshin Impact - Where to Find Crystal Cores
Crystal Cores come from catching Crystalflies. Every region's got its own elemental version: Anemo in Mondstadt, Cryo in Dragonspine, Geo in Liyue, Electro in Inazuma, Dendro in Sumeru, Hydro in Fontaine, and Pyro in Natlan, with Snezhnaya carrying its own variant too. Each one differing a bit in color and shape depending on where you catch it. Rather than trying to cover every single spot on the map, though, this guide sticks to the tightest route possible. Below are the locations that give you the most crystalflies for the least amount of running around.
NOTE: Since most of the map images below will highlight individual teleport points rather than a connected route, each location marks a teleport point with a high crystalfly count nearby, so you can spend less time traveling and more time actually farming. Alongside each spot, you'll also see a reference image from the interactive map showing just how cluttered the crystalflies get around that teleport point, which is exactly why these locations made the cut. This is also designed with daily farming in mind, since Crystalflies respawn regularly, so you can hit the same spots each day without extra planning.
Mondstadt
For Mondstadt, Windrise is really all you need, teleport to the Statue of the Seven there and you'll find half a dozen Anemo Crystalflies circling the tree right away. Below is the best Crystal Core spot for Mondstadt:
Mondstadt - Windrise
Liyue
Liyue's route covers two spots, Mt. Aocang and Guyun Stone Forest, both easily reached from their nearby domains and good for 8-10 crystalflies each. Below is the best Crystal Core spot for Liyue:
Liyue - Mt. Aocang
Liyue - Guyun Stone Forest
Inazuma
For Inazuma, Seirai Island is the spot, teleport in and you'll find a solid cluster of Electro Crystalflies waiting nearby. Below is the best Crystal Core spot for Inazuma:
Inazuma - Seirai Island
Sumeru
Sumeru offers a solid pair of spots, one near the Dendro Hypostasis and another around Yazadaha Pool, both easy to reach and worth adding to the daily route without much detour. Below are the best Crystal Core spots for Sumeru:
Sumeru - Around Yazadaha Pool
Sumeru - Near Dendro Hypostasis
Fontaine
Fontaine is hands-down the best region for farming Crystal Cores. With several dense, easy-to-reach spots packed close together, more than enough on their own to cover a full daily route without needing to touch any other region. Below is the best Crystal Core spot for Fontaine:
Fontaine - Court of Fontaine Region
Natlan
Natlan brings one standout cluster worth adding to the route, with five crystalflies packed closely together and just a short run from the nearest teleport point. Below is the best Crystal Core spot for Natlan:
Natlan - Ochkanatlan
Nod Krai
For Nod-Krai, Lempo Isle is the better of the two original spots, with 3 good Moonglow Firefly clusters scattered across it, while Paha Isle offers one more worth grabbing along the way. The Version 6.3 expansion north of Nod-Krai, home to Piramida and the Pillar of Embla, adds 4 more good spots on top of that. Below is the best Crystal Core spot for Nod Krai:
Nod-Krai - Lempo Isle
Nod-Krai - Paha Isle
Nod Krai - Expansion
Snezhnaya
For Snezhnaya, Volkodlak Tundra has 2 good spots worth hitting on your route, easy to grab while passing through the region.
Snezhnaya - Volkodlak Tundra
Genshin Impact - Tips in Farming Crystal Cores
A few small habits go a long way when it comes to farming Crystal Cores efficiently:
- Use Sayu, Lan Yan, or Yaoyao. All three have a passive that stops nearby Crystalflies from getting startled the moment you approach, meaning you won't lose any to them scattering before you even get close.
- Spam the interact button early. Start tapping right before the prompt fully appears rather than waiting for it, since Crystalflies react fast and a slight head start makes a real difference.
- Pair spamming with a forward jump on land. This helps you close the gap on flies that dart upward or away right as you approach.
- Farm at night when possible. Crystalflies glow in the dark, making them easier to spot compared to daytime lighting.
- Consider the Crystalfly Trap gadget. Available in Fontaine, it passively collects extra Crystal Cores over time and pairs well with a daily farming route instead of replacing it.
Conclusion
Farming Crystal Cores really isn't that complicated once you've got a route locked in. It comes down to hitting the right spots instead of chasing crystalflies all over the map. Stick to the locations above, bring Sayu, Lan Yan, or Yaoyao if you've got them, and you'll keep a steady stream of Condensed Resin ingredients coming in without much effort. Do it daily and it barely even registers as a grind. For Travelers planning to top up, head over to the Genshin Impact Top-up page on LootBar now!
