By day, Genshin Impact’s Diluc runs a winery, but by night he’s the legendary Darknight Hero who protects Monstadt in his own way. This claymore-wielding character harnesses the power of fire, making him one of the most powerful DPS characters in the game.

With help from our Genshin Impact Diluc build guide, you’ll soon know the best weapons and artifacts to equip, find out how much it’s going to cost you to upgrade his constellations, and get a rundown on all of his skills. We recommend using Diluc as your main DPS character and building your team up around him.

If you need some help with other popular characters, take a look at our Genshin Impact Eula and Genshin Impact Yanfei guides. We’ve also got a handy Genshin Impact codes list to get you some free primogems, and a Genshin Impact tier list to help you build up a full and powerful party.

The best Genshin Impact Diluc build

As mentioned above, we recommend using Diluc as your main DPS. He excels even further when paired up with a support character who can help Diluc trigger an elemental reaction. Suitable options include Genshin Impact’s Kaeya for the melt reaction, or Genshin Impact’s Fischl for overload.

Which weapon should you use?

We highly recommend going for the Wolf’s Gravestone due to its ability to increase all party members’ attack by 40%. Unfortunately, you need to be pretty lucky in order to obtain it from a wish, so the four-star Sacrificial Sword is a suitable option if you can’t get your hands on it.

Weapon Effect
Wolf’s Gravestone Increases attack by 20%. Attacks against enemies with less than 30% HP increase all party members’ attack by 40% for 12 seconds. This can only occur once every 30 seconds
Sacrificial Sword After damaging an opponent with an elemental skill, the skill has a 40% chance to end its cooldown. This can only occur once every 30 seconds

Which artifact set should you use?

Either of the artifact sets below are suitable for Diluc. Feel free to equip a full set or two of each to reap the damage benefits.

Artifact set Effect
Crimson Witch of Flames Two equipped: 15% pyro damage bonus
Four equipped: Increases overload and burn damage by 40%. Increases vaporize and melt damage by 15%. Using an elemental skill increases two-piece set effects by 50% for ten seconds. Maximum three stacks
Gladiator’s Finale Two equipped: Increases attack by 18%
Four equipped: If the wielder of this set uses a sword, claymore, or polearm, their normal attack damage is increased by 35%

Alternate artifact set

This set is a lot easier to get your hands on, go ahead and equip it until you get the sets above.

Artifact set Effect
Berserker Two equipped: increases critical rate by 12%
Four equipped: when Diluc’s HP is below 70%, critical rate increases by an additional 24%
