Last Updated: October 28, 2025

Flins unleashing his Electro abilities in Genshin Impact.

Flins has electrified the battlefield as a premier on-field Electro DPS in Genshin Impact, carving out a powerful niche with his relentless damage output. For any Traveler who has added this Inazuman storm-caller to their roster, unlocking his true potential is the top priority. Getting a five-star character to level 90 with highly-crowned talents requires a significant investment of time and Resin, but with careful planning, you can farm efficiently and build him into the meta-defining force he was designed to be.

This comprehensive guide covers every single Ascension and Talent material you need to fully level up Flins. We've detailed the exact quantities and the best locations to farm them, ensuring you can streamline the process and unleash his full power without delay.

Flins Ascension Materials & Farming Locations

To ascend Flins from level 1 to 90, you will need a combination of Electro gemstones, a world boss drop from the Thunder Manifestation, an Inazuman local specialty, and common materials from Nobushi samurai.

Total Materials for Ascension:

  • Vajrada Amethyst Sliver: 1
  • Vajrada Amethyst Fragment: 9
  • Vajrada Amethyst Chunk: 9
  • Vajrada Amethyst Gemstone: 6
  • Storm-Fused Core: 46
  • Naku Weed: 168
  • Old Handguard: 18
  • Kageuchi Handguard: 30
  • Famed Handguard: 36
  • Hero's Wit: 419 (or equivalent EXP materials)
  • Mora: 2,092,530

Material Farming Guide

Vajrada Amethyst & Storm-Fused Core

Both of these crucial materials are exclusive drops from the Thunder Manifestation on Seirai Island, Inazuma. To acquire the 46 Storm-Fused Cores needed, you’ll have to defeat this boss roughly 20-23 times, assuming an average of 2-3 drops per run. Each encounter costs 40 Original Resin. While farming the cores, you will naturally accumulate all the Vajrada Amethyst gemstones required for ascension.

Naku Weed

This local specialty of Inazuma thrives in areas with high Electro concentration. The best farming locations are around the Mikage Furnace in Tatarasuna and across the entirety of Seirai Island. A full clear of all nodes will net you over 100 weeds, which respawn every 48 hours. For a sustainable supply, you can also purchase 5 Naku Weeds from Babak in Port Ormos (Sumeru) and grow them in your Serenitea Pot using the Luxuriant Glebe furnishing.

Handguards (Old, Kageuchi, Famed)

These common materials are dropped by Nobushi and Kairagi samurai enemies, who are found roaming all over the islands of Inazuma. Efficient farming routes typically involve circling the coasts of Narukami Island, Kannazuka, and Yashiori Island. Use the in-game Adventurer Handbook to track their locations for a more direct farming session. You will need a large quantity of these for both ascensions and talents, so it's wise to farm them consistently.

Flins Talent Level-Up Materials

Leveling Flins' talents is where his damage potential truly skyrockets. To do so, you'll need Talent Books from the "Light" series, more Handguards, and a specific weekly boss drop from La Signora.

Total Materials for One Talent (to Level 10):

  • Teachings of Light: 3
  • Guide to Light: 21
  • Philosophies of Light: 38
  • Old Handguard: 6
  • Kageuchi Handguard: 22
  • Famed Handguard: 31
  • Molten Moment: 6
  • Crown of Insight: 1
  • Mora: 1,652,500

Note: To max out all three of Flins' talents (Triple Crown), you will need to multiply these amounts by three, requiring a total of 18 Molten Moments and 3 Crowns of Insight.

Talent Material Farming Locations

Talent Books: Teachings, Guide, & Philosophies of Light

These books are rewarded from the Violet Court domain in Inazuma on Wednesdays, Saturdays, and Sundays. To make the most of your Resin, it's highly recommended to use Condensed Resin for double rewards, effectively cutting your farming time in half.

Molten Moment (Weekly Boss Material)

This advanced material is one of three possible drops from the La Signora weekly boss challenge (Narukami Island: Tenshukaku) when challenged at level 70 or higher. Since you can only claim rewards once per week, it is essential to start fighting her as early as possible. If you receive her other materials (Ashen Heart or Hellfire Butterfly), you can use the rare Dream Solvent item at an alchemy table to convert them into the Molten Moment you need.

Crown of Insight

This is the rarest talent level-up material in the game. Crowns of Insight are primarily obtained as top-tier rewards from major limited-time events. A few can also be acquired through permanent offerings, such as leveling up the Frostbearing Tree in Dragonspine, the Sacred Sakura's Favor in Inazuma, and the Tree of Dreams in Sumeru. Use them wisely on Flins' most important talents, which for an on-field DPS are typically his Normal Attack and Elemental Burst.
