Chevreuse Build Guide 2026: Complete Ascension, Leveling & Talent Materials

In the ever-evolving world of Teyvat, new faces continue to join the roster, each bringing their own unique flair to the battlefield. As of 2026, Chevreuse, the steadfast captain of Fontaine's Special Security and Surveillance Patrol, remains a standout four-star Pyro polearm user. While she might have started as a minor character in the Fontaine storyline, she quickly carved out a major niche for herself, becoming a game-changer for teams centered around the explosive Overload reaction. Her strong sense of justice isn't just for show—it translates into a support kit that demands strategic play and proper investment to truly shine. Let's break down everything you need to build her up in the current year.

Ascending the Captain: From 1 to 90

Alright, let's talk about the grind—because leveling up a character is the most basic, yet absolutely fundamental, step to making them powerful. For Chevreuse, this journey is all about gathering specific Fontaine treasures. Her local specialty, the lovely Lumidouce Bell, is your first target. You'll need a whopping 168 of these flowers to see her through to Ascension Phase 6, meaning you're in for at least a couple of dedicated farming trips across the Court of Fontaine region. It's a bit of a hike, but hey, no one said justice was easy!

Besides the flowers, you'll be collecting Pyro Agnidus Agate stones and gears dropped from Fontaine's clockwork meka enemies. The real kicker, though, is the Fontemer Unihorn, a material dropped by the local world boss. Each challenge costs 40 Original Resin, and the drop rate can be, well, let's just say unpredictable—you might get one, two, or if you're lucky, three at a time. Here’s the complete breakdown of what you need for each ascension phase:

Total Ascension Mora Cost: 420,000 🪙

The Nitty-Gritty of Leveling Up

Once you've gathered all those ascension mats, it's time for the actual leveling process. This part often gets swept under the rug while everyone frets about boss drops, but forgetting about it is a big mistake you'll want to avoid. Leveling Chevreuse from 1 to 90 requires a mountain of Experience Books and a small fortune in Mora. The experience needed isn't linear—it skyrockets after level 80, so brace yourself!

Here’s the detailed cost for each level bracket, showing the most efficient use of your books (though a little EXP waste is practically unavoidable):

• Level 1 to 10: 5 Adventurer's Experience, 1 Wanderer's Advice | 5,000 Mora

• Level 10 to 20: 19 Adventurer's Experience | 18,800 Mora

• Level 20 to 30: 10 Hero's Wit, 2 Adventurer's Experience, 3 Wanderer's Advice | 42,400 Mora

• Level 30 to 40: 18 Hero's Wit, 1 Adventurer's Experience, 1 Wanderer's Advice | 73,000 Mora

• Level 40 to 50: 29 Hero's Wit | 115,800 Mora

• Level 50 to 60: 42 Hero's Wit, 3 Adventurer's Experience | 170,800 Mora

• Level 60 to 70: 59 Hero's Wit, 3 Adventurer's Experience, 1 Wanderer's Advice | 239,000 Mora

• Level 70 to 80: 80 Hero's Wit, 2 Adventurer's Experience, 2 Wanderer's Advice | 322,200 Mora

• Level 80 to 90: 171 Hero's Wit, 4 Wanderer's Advice | 684,600 Mora

Quick Reference - EXP Book Values:

• 🟢 Wanderer's Advice = 1,000 EXP

• 🟡 Adventurer's Experience = 5,000 EXP

• 🔴 Hero's Wit = 20,000 EXP

Doing the math, the total Mora cost just for leveling is 1,671,600. Add that to the 420,000 Mora for ascensions, and you're looking at a grand total of roughly 2,091,600 Mora to get Chevreuse from level 1 to 90. That's a lot of commissions! 💸

Honing Her Talents: The Path to Mastery

If ascension and leveling build her foundation, then talent levels are what truly unlock Chevreuse's potential. As a reaction-based support, she's a bit of a double agent—she enables powerful Overload reactions and uses them to buff herself and the team. This unique synergy means her talent levels aren't just about bigger numbers; they're about enabling an entire playstyle. Overload might be a niche reaction, but in Chevreuse's capable hands, it becomes a strategic powerhouse. That's why investing in her talents is non-negotiable.

The materials follow a pattern: "Teachings," "Guides," and "Philosophies" of Order from Fontaine's talent domain, more of those ever-present gears from the meka, and a special weekly boss material—the Lightless Eye of the Maelstrom. Planning your resin around weekly boss fights is crucial for the higher talent levels.

Total Mora for One Talent 1->10: ~1,653,500 (Yikes! 😅)

Remember, this cost is per talent. Chevreuse has three combat talents, so maxing them all is a true endgame goal that requires serious planning and patience.

Final Thoughts for 2026

Building Chevreuse is a commitment, but one that pays dividends for Overload-focused teams. She's not a character you just throw resources at; she asks for your time in Fontaine's fields, your resin against formidable foes, and your strategic mind in combat. The journey from a level 1 recruit to a level 90 captain supporting her squad with well-leveled talents is a classic Genshin progression saga. As the meta continues to shift, her unique role as an Overload specialist keeps her relevant. So, if you're looking to add some explosive, justice-driven support to your roster, start farming those Lumidouce Bells—your future team will thank you. The path is clear, the materials are listed... the rest is up to you, Traveler.

Data referenced from Esports Charts helps contextualize why specialized support units like Chevreuse can surge in popularity when certain team archetypes become more visible in high-engagement play, reinforcing the idea from the guide that properly investing in her ascension and talent materials can pay off once Overload-centric strategies gain momentum across the broader player ecosystem.
