Diluc is easiest to build when you decide the job first, then let weapons, artifacts, and teammates serve that job. For most accounts, Diluc works best as on-field Pyro DPS for Vaporize, Melt experiments, and Plunge teams, so this guide focuses on practical gear choices, talent priority, team structure, rotation comfort, and the materials you should expect before committing resin.
Quick answer: Build Diluc around on-field Pyro DPS for Vaporize, Melt experiments, and Plunge teams. Prioritize normal attack and skill first, then burst; plunge teams value normal attack more, use 4pc Crimson Witch of Flames for reaction DPS as the first artifact target when it fits the team, and pick weapons from the recommended list only after the rotation has enough energy and survivability.
Diluc's role, element, weapon type, and talent names give the guide its baseline; the build advice below turns that profile into practical choices for current accounts.
Diluc should be treated as on-field Pyro DPS for Vaporize, Melt experiments, and Plunge teams. That one decision controls the artifact set, main stats, weapon value, and whether the team needs a battery, healer, shield, or stronger off-field application.
| Build choice | Recommended setup | When to use it |
|---|---|---|
| Main role | on-field Pyro DPS for Vaporize, Melt experiments, and Plunge teams | Use this to decide field time and team order. |
| Artifact direction | 4pc Crimson Witch of Flames for reaction DPS, 4pc Marechaussee Hunter with Furina setups, or mixed Pyro/ATK pieces early | Choose the set that supports the role before min-maxing substats. |
| Main stats | ATK or EM sands depending on Vaporize uptime, Pyro DMG goblet, CRIT circlet | Fix energy, scaling stat, and survival before showcase CRIT. |
| Talent order | Normal Attack and Skill first, then Burst; Plunge teams value Normal Attack more | Level what the rotation actually uses. |
| Icon | Recommendation | Use case |
|---|---|---|
![]() | Redhorn Stonethresher 5-Star, CRIT DMG | Use when its sub-stat or passive supports the rotation. |
![]() | Wolf's Gravestone 5-Star, ATK Percentage | Use when its sub-stat or passive supports the rotation. |
![]() | Beacon of the Reed Sea 5-Star, CRIT Rate | Use when its sub-stat or passive supports the rotation. |
![]() | Serpent Spine 4-Star, CRIT Rate | Use when its sub-stat or passive supports the rotation. |
![]() | Mailed Flower 4-Star, Elemental Mastery | Use when its sub-stat or passive supports the rotation. |
![]() | Rainslasher 4-Star, Elemental Mastery | Use when its sub-stat or passive supports the rotation. |
When choosing between weapons, test the second rotation rather than only the first burst window. If Diluc loses Burst uptime or the support passive misses the main damage window, a lower-rarity weapon with the right stat can be the better build.
| Icon | Recommendation | Use case |
|---|---|---|
![]() | Crimson Witch of Flames ★★★★, DMG Bonus | Use when the set bonus matches the role described above. |
![]() | Marechaussee Hunter ★★★★, DMG Bonus | Use when the set bonus matches the role described above. |
For stats, start with ATK or EM sands depending on Vaporize uptime, Pyro DMG goblet, CRIT circlet. If the recommended artifact table and your account situation disagree, prioritize the stat that keeps Diluc's real rotation functioning, then improve substats gradually.

Priority: Normal Attack and Skill first, then Burst; Plunge teams value Normal Attack more

Normal Attack Perform up to 4 consecutive strikes. Charged Attack Drains Stamina over time to perform continuous slashes. At the end of the sequence, perform a more powerful slash. Plunging Attack Plunges from mid-air to strike the ground, damaging opponents along the path and dealing AoE DMG upon impact.

Priority: Normal Attack and Skill first, then Burst; Plunge teams value Normal Attack more

Performs a forward slash that deals Pyro DMG . This skill can be consecutively used 3 times. Enters CD if not cast again within a short period. The slashes represent the values that Diluc holds dear: one for justice, one for courage, and one for duty.

Priority: Normal Attack and Skill first, then Burst; Plunge teams value Normal Attack more

Releases intense flames to knock back nearby opponents, dealing Pyro DMG . The flames then converge into the weapon, summoning a Phoenix that flies forward and deals massive Pyro DMG to all opponents in its path. The Phoenix explodes upon reaching its destination, causing a large amount of AoE Pyro DMG . The searing flames that run down his blade cause it.
Rotation note: set Hydro and buffs first, weave Skill casts between Normal Attacks, Burst to maintain Pyro flow, and avoid missing Vaporize ownership. The GIFs above are useful for checking timing, range, and animation commitment before you decide how much field time Diluc should take.

Use this shell when it supports Diluc's energy, reaction ownership, and field-time window without forcing awkward swaps.

Example: Diluc / Cryo applier / Bennett / Anemo support
Use this shell when it supports Diluc's energy, reaction ownership, and field-time window without forcing awkward swaps.
Team examples are functional shells, not fixed account rules. Replace premium units with characters that perform the same job: application, battery, buff, resistance shred, healing, or shielding.
Diluc is worth building if you like steady melee Pyro gameplay or own Xianyun/Furina-style supports that refresh his ceiling.
The safest Diluc build focuses on on-field Pyro DPS for Vaporize, Melt experiments, and Plunge teams. Start with 4pc Crimson Witch of Flames for reaction DPS, 4pc Marechaussee Hunter with Furina setups, or mixed Pyro/ATK pieces early and use ATK or EM sands depending on Vaporize uptime, Pyro DMG goblet, CRIT circlet before chasing perfect substats.
Use the weapon table as a starting point when it matches your stat needs, then compare them with flexible options such as Redhorn Stonethresher, Wolf's Gravestone, Beacon of the Reed Sea, Serpent Spine, Mailed Flower, Rainslasher for Vape, or Prototype Archaic.
Use teams that protect Diluc's rotation: the examples above cover Vaporize, Plunge Pyro, Melt experiment.
Yes, but follow the priority. For most builds: Normal Attack and Skill first, then Burst; Plunge teams value Normal Attack more.
Diluc is worth building if you like steady melee Pyro gameplay or own Xianyun/Furina-style supports that refresh his ceiling.
A strong Diluc build is a full account plan: official kit facts, exact material costs, weapon and artifact choices, then a team that keeps the rotation repeatable. Start with the role, test the second rotation, and only then spend resin on refinements.
