Diluc: The Dark Side of Dawn

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


Updated For Version 2.4

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.

Here is a quick TL;DR on him, brought to you by KQM at discord.gg/keqing

Pros and Cons

Pros:

  • Easy to play.
  • Has access to amplifying reactions.
  • Blunt + 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.
  • Lower burst potential compared to other Pyro carries.
  • No real signature weapon to amplify his damage. 

Talents and Constellations

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.

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.

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.

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.

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.

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.

Conviction

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

If your attack would end up killing them when they’re above 50% HP, you can have “full uptime” on the Constellation. However, the damage increase is dependent on enemy, making it’s value and damage increase variable depending on the content.


Estimated DMG Increase From C0 (50% Uptime): 4%

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.


Estimated DMG Increase From C1 (3 Stacks): 9%

Fire and Steel

Increases the Level of Searing Onslaught by 3.


Diluc’s 3rd Constellation. Not much to say, Talent Level Increase by 3.


Estimated DMG Increase From C2: 5.5%

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. The issue with this Constellation is that it doesn’t work if you don’t wait at least two seconds. As a result you need to either wait or weave in a 3rd Normal Attack in between Elemental Skills.


Estimated DMG Increase From C3: 0% if not 3x Weave or Delay, 3% if 3x Weave 

Phoenix, Harbinger of Dawn

Increases the Level of Dawn by 3.


Diluc’s 5th Constellation. Similar to C3. Just a flat increase in damage.


Estimated DMG Increase From C4: 5% Increase if Double Weave, 4.5% if Triple Weave

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. The issue regarding this Constellation and its value is how Diluc can “skip” his Normal Attack string. By canceling the start up for his Normals using his Elemental Skill, he can move onto the next Normal Attack in the string. 


As of now, this has not been explored to a large degree and it’s overall damage increase is unknown
outside of the flat 30% DMG on his Normals.

Talent Priority:

Searing Onslaught => Tempered Sword > Dawn


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

Combos and Dragon Strike:

Standard Combo: 

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

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.


Example Here: https://imgur.com/a/QPaai8n

Dragon Strike Combo:

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.

Gear

Calcs done by elijam#7142

Diluc is commonly and recommended to be paired with Bennett due to their high synergy. Although playing in the small circle range can be difficult at times, the amount of ATK buffs Bennett provides to Diluc almost doubles his damage. Although you can play Diluc without Bennett, you lose a significant amount of damage. As a result of how often Diluc is paired with Bennett, this section will include calculations for both Unbuffed and Buffed. All calcs are done using the KQM Calculation Standards.

Generally WGS is the go-to pick when unbuffed due to having an easier conditional to deal with in comparison to Serpent Spine R5. However, with the release of Redhorn, it can serve as a viable option, especially when unable to get the WGS Passive.

Buffed:

Serpent Spine is by far the strongest option. Although its passive can be hard to maintain without a shield, the amount of damage obtained through its passive cannot be ignored. Redhorn is also a strong option when maintaining the passive stacks cannot be done.

Artifacts

The 4-piece CWoF set is the best set for Diluc as its passive is tailor made for Diluc. However, to some, the CWoF domain may seem inefficient compared to other artifact domains. The next best option is a 2-piece combination between 2CWoF and 2SR. 2WT can also be an option however it is harder to farm in comparison to 2SR. 

Stat Priority

Sands: EM or ATK%

Goblet: Pyro%
Circlet: CRIT Rate% or CRIT DMG%

Substats: CRIT Rate = CRIT DMG > EM => ATK%


Generally, Diluc will be buffed, increasing the value of EM substats and EM Sands. When it comes to the Sands, it will largely depend on the weapon. Generally EM will be the choice when buffed however due to the difficulty of obtaining EM Sands with good substats, ATK% may yield higher results.

Team Comps

Vaporize

This is the main Diluc team. Due to Diluc performing many Normal Attacks in his main combo, he can summon many rainswords from Xingqiu, which allow him to vaporize his damage. Bennett provides large amounts of ATK buffs and almost doubles Diluc’s overall damage dealt through them. These three are practically glued together when it comes to Vaporize Diluc.

Flex Options

These are the five 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 XQ (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) and he will apply Pyro, thus ruining the next vaporises.


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 absorb Pyro which can steal vapes from Diluc. Trying to absorb 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.

Melt

Melt Diluc has had a recent surge in popularity due to optimizations in rotations. The general core is Diluc and Bennett with either Kaeya and Kazuha or Rosaria and Sucrose. By absorbing Cryo, there is enough Cryo application to supply Diluc for the end of his main combo string, allowing him to forward melt consistently. 


Typically other variations of Melt either had inconsistencies in who was melting and/or sacrificed things such as 4VV shred, causing them to perform worse than standard Vaporize Diluc. These teams can stay relatively competitive while also freeing up Xingqiu for a different team.


Kaeya and Kazuha Variation requires a specific Diluc Combo:
E1 > Q > N1 > E2 > N1 > E3


While the Rosaria and Sucrose Variation performs N2s weaved in.


Example Rotations: diluc example rotations – YouTube


Do note that 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 her high burst cost and Diluc losing personal damage to maximize on Beidou’s damage. If you want to use Beidou and maximize on her potential, I’d 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.


Overvape teams can be ran if the Overload reactions don’t cause unwanted knockback. Typically this requires sacrificing a flex option for Fischl, which can be worth it in some scenarios. However, the resistance shred offered by 4VV reigns supreme if pulled off correctly and Overvape teams should only be ran when 4VVing Pyro is not easy to perform.

Pure Pyro


Pure Pyro Teams can be ran when raw elemental damage is preferred over reactions. Anemo units can provide the team with Resistance Shred and Kazuha specifically can provide large DMG% buffs to the team. Zhongli provides a safer option for players who need the extra survivability/interruption resistance.
