Here’s everything in our Genshin Impact Diluc guide:
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 Kaeya for the melt reaction, or 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% |

What are Diluc’s constellations?
Although Diluc is extremely powerful without any constellations at all, powering them up to level six will make him an unstoppable powerhouse.
| Constellation | Effect |
| Conviction | 15% more damage is dealt to enemies with HP above 50% |
| Searing Ember | When Diluc takes damage, his base attack is increased by 10% and his attack speed by 5%. This lasts for ten seconds. Can stack up to three times and can only occur once every 1.5 seconds |
| Steel and Fire | Increases the level of Searing Onslaught by three |
| Flowing Flame | Within two seconds of using Searing Onslaught, casting the skill again in a combo deals 40% additional damage. This effect lasts for the next two seconds |
