Diluc Ascension and Talent Materials in Genshin Impact

If you want to build Diluc in Genshin Impact, you need to know exactly what materials to farm and where to find them. This guide covers every ascension phase, every talent level, and all the farming locations so you can get him to level 90 without wasting time.

Diluc is a 5-star Pyro Claymore user and one of Mondstadt’s strongest main DPS characters. He has been a top pick since launch, and his kit still holds up well, especially with modern team compositions featuring Xianyun, Furina, and Bennett. If you are planning to pull him or already have him, investing in his ascension and talents is absolutely worth it.

Where to Farm Diluc’s Ascension Materials

Agnidus Agate — How to Get It

Agnidus Agate drops from Pyro bosses. The best source is the Pyro Regisvine, located in Cuijue Slope in Liyue. This boss costs 40 Original Resin per run. The Pyro Hypostasis is another option. You can also convert gem types at the Crafting Bench using the alchemy table if you have excess gems of a different element.

Everflame Seed — How to Get It

The Everflame Seed drops exclusively from the Pyro Regisvine boss. There is no other way to get it. This means you will be farming this boss quite a lot, so plan your Original Resin accordingly. The Pyro Regisvine is found underground in Tianqiu Valley in Liyue. No quest unlock is required — you can go directly to its location from the start.

Small Lamp Grass — How to Get It

Small Lamp Grass is Mondstadt’s local specialty for Diluc. It is easier to spot at night because it glows with a faint blue light. The best farming locations are Whispering Woods and Wolvendom. You can also find it around Stormterror’s Lair. The plant respawns every two days. Use the in-game Collection Area Markers to track your farming route across sessions.

Fatui Insignia — How to Get It

Recruit’s Insignia, Sergeant’s Insignia, and Lieutenant’s Insignia all drop from Fatui enemies. The rarity of the drop depends on the level of the enemy. High-level Fatui Skirmishers on the north shore of Dragonspine are a popular farming spot. You can also find Fatui enemies scattered across all nations in Teyvat. The Adventurer’s Handbook also points you toward Fatui enemy locations early in the game.

Diluc Talent Materials — Full List

To max out all three of Diluc’s talents to level 10, you need the following:

Teachings of Resistance ×9

Sergeant’s Insignia ×66
Lieutenant’s Insignia ×93
Dvalin’s Plume ×18 (weekly boss material)

Diluc Talent Level Breakdown

6 Recruit’s Insignia
3 Teachings of Resistance

Talent Level 3

17,500 Mora

Talent Levels 7–9

From level 7 onward, you need Philosophies of Resistance and Lieutenant’s Insignia. Mora requirements increase sharply at these levels.

Talent Level 10

The final talent level requires a Crown of Insight in addition to the usual materials. You need one Crown of Insight per talent to reach level 10. Crowns are rare and mostly available through limited events.

Where to Farm Diluc’s Talent Materials

Books of Resistance — Forsaken Rift Domain

The Teachings, Guide, and Philosophies of Resistance all come from the Forsaken Rift domain in Mondstadt. This domain rewards Resistance books on Tuesday, Friday, and Sunday. You can also occasionally get books from chests or limited-time events, but the domain is your main source.

Dvalin’s Plume — Stormterror’s Domain

The Dvalin’s Plume is the weekly boss material for Diluc’s talents. It drops from the Stormterror (Dvalin) weekly boss fight, which is located in Stormterror’s Lair in Mondstadt. To unlock this domain, you must complete Archon Quest Prologue Act 3: Song of the Dragon and Freedom. This is a weekly boss, so you can only farm it once per week for the discounted resin cost. If you are also farming for other Mondstadt characters, check out our Azhdaha trounce challenge guide to compare boss farming strategies.

The first three weekly bosses you challenge each week cost only 30 Original Resin instead of the usual 60. Make sure Dvalin is one of your priority weekly bosses while farming for Diluc.

Crown of Insight

The Crown of Insight is the rarest talent upgrade material in the game. It cannot be farmed on demand. You can earn it from limited-time events that appear during each game version, and sometimes by upgrading special progression trees like the Frostbearing Tree in Dragonspine or the Sacred Sakura in Inazuma. Only push talents to level 10 on Diluc’s most important skills if you are willing to spend a Crown.

Diluc Talent Priority

Diluc is a main DPS character. All three of his talents contribute to his overall damage, so you want to keep them close in level. That said, here is how to prioritize if you are limited on resources:

Elemental Skill (Searing Onslaught) — highest priority; this is Diluc’s main damage tool
Normal Attack (Tempered Sword) — second priority; normal attacks fill gaps between skill uses
Elemental Burst (Dawn) — third priority; powerful but used less frequently in rotations

If you are running Diluc in a Plunge team with Xianyun, note that plunge attack damage scales with the Normal Attack talent. In that case, you may want to level Normal Attack higher than usual.

For team composition ideas and support pairing, you can also check how characters like Bennett and Xingqiu interact with Diluc to maximize Vaporize damage. Learn more about best weapons for Bennett to keep your support slots optimised.

Full Farming Schedule for Diluc

Here is a simple daily farming plan to get Diluc to level 90 with level 8/8/8 talents:

Tuesday / Friday / Sunday: Run Forsaken Rift domain for Resistance books
Every day: Farm the Pyro Regisvine for Everflame Seed and Agnidus Agate. Spend Original Resin here first
Every 2 days: Collect Small Lamp Grass across Whispering Woods and Wolvendom
Daily (passive): Defeat Fatui enemies encountered during exploration or commissions for Insignia drops
Weekly: Challenge Stormterror for Dvalin’s Plume

At minimum, expect to spend around 2,000 Original Resin to collect all the boss and domain materials for full ascension and 8/8/8 talent levels. Farming from scratch with no extra resin will take at least one week.

Diluc’s Talents and Abilities Overview

Normal Attack: Tempered Sword

Diluc performs up to four consecutive strikes with his claymore. His charged attack drains stamina over time to deliver continuous slashes, finishing with a powerful final hit. A passive talent reduces the stamina cost of his charged attack by 50% and increases its duration.

Elemental Skill: Searing Onslaught

Diluc performs a forward slash that deals Pyro DMG. This skill can be used up to three times consecutively before going on cooldown. Each slash represents one of his personal values — justice, courage, and duty. This is the core of his damage rotation.

Elemental Burst: Dawn

Diluc unleashes a wave of flames, knocking back enemies and dealing Pyro DMG. A phoenix then flies forward, dealing large AoE Pyro damage on impact. After the burst, his blade is infused with Pyro for a period. A passive also grants him a 20% Pyro DMG Bonus for 12 seconds after using Dawn. This makes his burst a major damage window even in shorter rotations.

Diluc’s Passive Talents

Relentless (1st Ascension Passive): Reduces charged attack stamina cost by 50% and increases its duration by 3 seconds.
Blessing of Phoenix (4th Ascension Passive): The Pyro Infusion from Dawn lasts 4 seconds longer. Diluc gains 20% Pyro DMG Bonus during this time.
Tradition of the Dawn Knight (Utility Passive): Refunds 15% of the ores used when crafting Claymore-type weapons.

Diluc Constellations Overview

You unlock constellations by getting duplicate copies of Diluc from the standard wish banner. Since he is a standard 5-star, getting constellations is possible but takes time. Here is what each one does:

C1 — Conviction: Diluc deals 15% more DMG to enemies with HP above 50%.
C2 — Searing Ember: When Diluc takes damage, his ATK increases by 10% and ATK SPD increases by 5%. Stacks up to 3 times.
C3 — Fire and Steel: Increases Searing Onslaught level by 3 (max level 15).
C4 — Flowing Flame: Casting Searing Onslaught in sequence boosts the next hit by 40% if cast within 2 seconds.
C5 — Phoenix, Harbinger of Dawn: Increases Dawn (Elemental Burst) level by 3 (max level 15).
C6 — Flaming Sword, Nemesis of the Dark: After using Searing Onslaught, normal attacks deal 30% more DMG for 5 seconds. Searing Onslaught also no longer resets the normal attack combo.

C1 and C2 are solid early constellations that noticeably boost combat performance. C6 is transformative for his playstyle. For context on how powerful buff supports can be, you can also read about best weapons for Kujou Sara, another strong Pyro-adjacent support.

Where to Get Diluc

Diluc is available on the Standard Wish banner (Wanderlust Invocation), which is always available in the game. He does not appear on limited character event banners. This means you can pull him from the standard banner at any time, and you may also receive him as a guaranteed 5-star reward from the Beginner’s Wish banner.

You can play Genshin Impact for free on multiple platforms:
