Diluc: The Dark Side of Dawn

Written by: xf3#3123, Ayzel#7399, and EdisonsMathsClub#6469


Updated For Version 2.0

Preface

Diluc is widely known as the poster boy for Pyro DPS in Genshin Impact. He’s the most reliable Pyro DPS in the game. His consistency is so appreciated that he is widely used as the benchmark for on field DPS characters. Diluc’s simplicity makes him easy to play and pick up for any player. However, he does some mechanics that allows him to be played with more mechanical skill.

Pros and Cons

Pros:

  • Easy to play
  • Has access to amplifying reactions (Vaporise in particular)
  • Blunt (property to break ores/shatter) + Pyro, allows him to break all common shield types (non elemental)
  • Very little resource management

Cons:

  • Has a useless A1 passive
  • Extremely limited team compositions when playing him optimally 

Talents and Constellations

Normal Attack: Tempered Sword


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.


Diluc’s Normals are fairly simple and fluid. Never use his charged attack. He has the highest plunge modifier in the game, making Dragon Striking a viable technique.

Elemental Skill: Searing Onslaught

Performs a forward slash that deals Pyro DMG. This skill can be used 3 times consecutively. Enters CD if not cast again within a short period (5s).


Diluc’s Elemental Skill is effective and easy to use. Weave in Normal Attacks in between each use of Searing Onslaught.

Elemental Burst: Dawn

Releases intense flames to knock nearby opponents back, 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 to be infused with Pyro.


Diluc’s Elemental Burst. Knocks lighter enemies away, which can be annoying, but can also be used to group tougher mobs such as Abyss Lectors. At A4, use this skill before starting your rotation to maximize on damage.

Ascension 1 Talent: Relentless

Diluc’s Charged Attack Stamina Cost is decreased by 50%, and its duration is increased by 3s.


Diluc’s Ascension 1 Talent. It might be the worst Talent in the game. Never use his Charged Attack.

Ascension 4 Talent: Blessing of the Phoenix

The Pyro Enchantment provided by Dawn lasts for 4s longer. Additionally. Diluc gains 20% Pyro DMG Bonus during the duration of this effect.


Diluc’s Ascension 4 Talent. Free DMG%. Use Dawn before starting rotations to maximize on damage.

Passive: Tradition of the Dawn Knight

Refunds 15% of the ores used when crafting Claymore-type weapons.


Diluc’s Utility Passive. Helpful for crafting Prototype Archaic, one of his weapon options for F2P players.

Constellations

Constellation 1: Conviction

Diluc deals 15% more DMG to opponents whose HP is above 50%.


Diluc’s 1st Constellation. Just adds damage.

Constellation 2: Searing Ember

When Diluc takes DMG, his ATK increases by 10% and his ATK SPD increases by 5%. Lasts for 10s.

This effect can stack up to 3 times and can only occur once every 1.5s.


Diluc’s 2nd Constellation. Give you free damage when you get hit and speeds up his normal weaving. Works when shielded as well. It has anti-synergy with Serpent Spine since this Constellation benefits being hit, whereas Serpent Spine discourages from being hit. However, running a shield user negates this issue. Just adds damage.

Constellation 3: Fire and Steel

Increases the Level of Searing Onslaught by 3.


Diluc’s 3rd Constellation. Talent level increases. Just adds damage.

Constellation 4: Flowing Flames

Casting Searing Onslaught in rhythm greatly increases damage dealt.

2s after casting Searing Onslaught, casting the next Searing Onslaught in the combo deals 40% additional DMG. This effect lasts for 2s.


Diluc’s 4th Constellation. Weave in Normal Attacks after Searing Onslaught. Just adds damage.

Constellation 5: Phoenix, Harbinger of Dawn

Increases the Level of Dawn by 3.


Diluc’s 5th Constellation. Talent level increases. Just adds damage.

Constellation 6: Flaming Sword, Nemesis of the Dark

After casting Searing Onslaught, the next 2 Normal Attacks within the next 6s will have their DMG and ATK SPD increased by 30%.

Additionally, Searing Onslaught will not interrupt the Normal Attack combo.


Diluc’s 6th Constellation. Weave in 2 Normal Attacks after each Searing Onslaught. Just adds damage.

Talent Priority:

Searing Onslaught => Tempered Sword > Dawn


Generally, you want to keep all 3 equally leveled, but focus on Skill > Normal > Burst.

Combos:

Standard Vape: 

Burst > N1 > Skill1 > N2 > Skill2 > N2 > Skill3 > N4 

Dragon Strike: 

Burst > Skill1 > N1 > P > Skill2 > N1 > P > Skill3 > N1 > P     


OR


Burst > N1 > P > Skill1 > N1 > P > Skill 2 > N1 > P > Skill 3 > N1 > P


Either combo works, but Dragon Striking off of Searing Onslaught is easier than N1.

Serpent with EM sands gets lowered without Bennett buff, but you should be playing Bennett with Diluc anyway. 


Details: The sheer value of Bennett’s ATK buff means going EM on the hourglass and weapons that offer other stats apart from ATK (such as DMG%/cRATE from Serpent Spine, or EM on Rainslasher) results in more damage gain. Rainslasher is also a fairly good choice for any Diluc, assuming 100% hydro uptime on Xingqiu (requiring high refine Sacrificial Sword or high energy recharge).

Artifacts

Crimson Witch of Flames

2-Piece Bonus: Pyro DMG Bonus +15%


4-Piece Bonus: Increases Overloaded and Burning DMG by 40%. Increases Vaporize and Melt DMG by 15%. Using an Elemental Skill increases the 2-Piece Set Bonus by 50% of its starting value for 10s. Max 3 stacks.


The 4 piece Bonus activates for every press of Diluc’s Elemental Skill, Searing Onslaught. This means you are able to get 3 stacks, resulting in 22.5% Pyro DMG bonus, and Diluc’s Elemental Skill cooldown is short so you are able to maintain it always.


This artifact set is literally made for Diluc. Farm for a 4pc set.


Go for ATK% / PYRO% / CRIT when using weapons without an ATK% substat. 
Use EM / PYRO% / CRIT for weapons that have an ATK% substat.


Substats: CRIT > ATK > EM

Dragon Strike

Dragon Strike is a technique which involves Dash Jump canceling and plunging immediately after generating hitlag. Diluc can generate this hitlag with both his normal attacks and his elemental skill. Due to his great plunge modifier and the fact that he can have his plunges infused with Pyro due to his elemental burst, Diluc can make great use of Dragon Strike to increase his DPS.


However, the technique is difficult, especially without movement speed increasing effects, such as Jean C2, Diona’s Shield, and Anemo Resonance. A more in depth explanation is on the KeqingMains Theorycrafting Library.

Team Comps

Vaporize

This is the main Diluc team. Diluc is practically married to Xingqiu. Because Diluc normal attacks practically all the time, Xingqiu’s rainswords are always triggering. This allows Diluc to get many vaporize reactions in one rotation. Bennett acts as the healer for the team and he also buffs Diluc’s ATK on top of enabling Pyro Resonance. At C6 Bennett also provide PYRO% for Diluc but be aware of the ramafications of C6 Bennett on other team comps.


This shell basically cannot be broken. Other team comps involving Melt reactions using Chongyun, Kaeya, Rosaria, or Ganyu are not recommended due to how much Diluc relies on Xingqiu for his damage on top of VapeMelt teams not functioning properly for Diluc due to Diluc Shattering any freeze reaction and not actually melting. Pure melt teams involve issues with uptime and consistency. Overload with Fischl over Xingqiu is only recommended against Geo Shield floor enemies. More details below.


However, the shell can be broken when focusing on Dragon Strike. Double Anemo can be used over Bennett to make Dragon Strike easier due to its movement speed buff.


If you absolutely need to, you can break the shell to fit certain elements against specific enemies, such as using Chongyun over a flex slot to break Abyss Herald shields.

Flex Options


These are the four main Flex options Diluc has, all with their strengths and weaknesses.


Sucrose offers VV shred, EM share, and grouping. However if you somehow use her Elemental Burst and if it infuses with Pyro, this can ruin vapes for Diluc. Thus, it is advised to not Elemental Burst at all, even at c6 Sucrose.


Zhongli offers survivability and Omnishred with his shield. However, his pillar can ruin the Hydro aura for Xingqiu (more of a risk at pre C6 XQ) which can ruin vapes for Diluc.


Diona typically offers nothing much aside from her shield and more healing, but she offers movement speed with her shield, making Dragon Strike easier and at C6, 200 EM. However, her burst can apply Cryo and freeze the enemy, and due to Diluc’s shatter properties, he will shatter (not melting at all).


Jean offers VV shred, Healing, and at C2, movement speed for Dragon Strike.


Although Kazuha can be used with Diluc similarly to Sucrose, he also has many issues. Kazuha will almost always infuse Pyro which can steal vapes from Diluc. Trying to infuse Kazuha Slash with Hydro prevents rainswords from triggering due to Kazuha’s long animations and on field time.


Venti is not recommended with Diluc in a pure synergistic way. Diluc cannot normally attack what is inside of Venti’s ult and Searing Onslaught can miss as well. Although Dawn can hit whatever is in the Stormeye, it’s not a synergy that is defining (ex. Venti Ganyu). However, if you choose to use Venti to clear light mob floors that is perfectly fine, however, it’s not really considered to be a “Diluc Team,” moreso a Venti Walking 3 Dogs Team.

Notes on Other Diluc Teams

Melt and VapeMelt


Melt Diluc is not recommended, unless your Xingqiu is paired with another character, not invested at all, or you don’t own him. The teams are less versatile and have issues with uptime and consistency. 


Chongyun works to apply Cyro and he’s dirt cheap to build for the team. However, he can only apply Cyro for one set of Searing Onslaught, as you have to infuse your weapon with Dawn at some point, which overrides Chong’s infusion. You also cannot start Diluc’s part of the rotation with a Cryo infused auto, it breaks the set up due to ICD. If you ever enable C6 Bennett, you can no longer run Melt Diluc with Chong and Bennett on the same team. 


If you do decide to use Chongyun for Diluc Melt, melt your three Searing Onslaughts and your Dawn after applying Cyro with infused autos. 


Combo is: CY Skill > Diluc Skill1 > N2 > Skill2 > N2 > Skill3> N2 > Burst > N1 > Skill1> N1 > Skill2 > N1 > Skill3 > N4


Kaeya and Rosaria do not apply fast enough Cryo for Diluc to Melt and they even can steal some melts if you don’t delay your attacks on Diluc. Running them both at the same time can help mitigate that but you lose your flex slot and the set up still isn’t as consistent as Xingqiu alone. Ganyu’s icicles are too inconsistent to apply Cyro due to their randomness, on top of her high burst cost.


VapeMelt strictly does not work on Diluc. Like Klee, Diluc will shatter the freeze reaction causing you to actually lose damage compared to just vaping or melting. 

Overload and Taser


Overload is only recommended if you’re under AR45 and/or playing into a Geo Shield focused room to help break them. In addition, out of the 3, Fischl is the only one who is recommended. Her uptime is greater than the other two due to how long Oz stays on the field and her lower burst cost. Beidou is not really recommended due to Diluc losing personal damage to maximize on Beidou’s damage, as you stop N2ing, and her high ult cost. If you want to use Beidou and maximize on her potential, it is recommend checking out the Beidou Guide by ZΛNTO#4984. Lisa’s high energy cost and somewhat poor energy gain prevents her from being used in a sustained rotation. In addition, Overload reactions push enemies out of her ultimate, preventing the set up to be used outside of heavy enemies, like Ruin Guards.


Taser is not recommended due to SuperVape being patched out of the game as of the time of writing this guide. However, like how Chongyun and Venti mentioned in the Main Core and Flex Options sections, if you need Electro to clear content, go for it.

Pure Pyro


Pure Pyro teams can be used with Kazuha or Zhongli/Albedo with 4pc Archaic Petra into heavy Cryo enemy focused content. Both Kazuha’s A4 and Archaic Petra’s 4 piece set bonus give Diluc and Xiangling a lot of PYRO%. Issues occur with Xiangling’s high burst cost unfortunately.
