Yelan Quick TL;DR Support Build Guide

PSA #1: A Support is that friend who is the designated driver whenever you and the boys/girls go gambling and waste all your money on booze

PSA #2: Both Yelan’s abilities scale off HP and she is arguably one of the easiest off-field DPS Supports to build currently in the game! Slap some HP on her!

Yelan becomes Danny Phantom and can run through enemies. Running through enemies marks them and leaving her ghost state makes marked enemies take Hydro DMG

Before we start, I want to talk about Breakthrough State. I opted to not go into too much detail as her core gameplay is similar to Xingqiu: off-field and quick swap. Therefore she doesn’t utilize this much unless C6’d. However, I thought it would be important to mention that the more enemies she marks with E, the higher chance Breakthrough state will reset (since she can’t enter Breakthrough while in combat).

4 Main things with Yelan’s E:

  1. Tapping E will cause her to dash a set distance (has autoaim, so can just line them up and tap E)
  2. Holding E will allow you to control Yelan for 3 seconds
  3. While Holding E, Yelan gains movement speed and significant DMG reduction (or so it seems)
  4. You can explode the marks earlier by using E again, jumping, or dashing

In 9 out of 10 cases, Holding E > Tapping E as you will be able to mark all the enemies you want. Yelan’s E HP scaling is insane, and can easily hit 20k per proc with sub-optimal gear. Only real reason to Tap E is if you’re trying to quickly gain energy or quickswap before a buff runs out.

It’s also a great repositioning and mobility skill with a 10 second CD, so feel free to utilize it freely!

Yelan throws a dice into the air and does AoE Hydro DMG??? Then the dice basically spits out 3 homing missiles that do Hydro DMG. Stays when you swap characters!

This is Yelan’s core ability, and what makes her into a beastly off-field DPS/Support. It’s basically Xingqiu’s Q on crack as the projectiles are fast, rarely miss, and require less energy for uptime.

Some notable points:

  • Is lower energy cost, CD, projectile is faster, and more accurate than Xingqiu’s Q
  • Only procs on Normal Attacks and Yelan’s E mark explosions
  • Q is dynamic, not snapshot. Meaning you can earn/lose buffs in real time

Q damage is no joke, as it scales off Max HP. If your Yelan has 30,000 HP, that means in total a single Q proc can do 7,020 DMG ([30,000 x 0.078] x 3) BEFORE DMG bonus/CRIT calculations. You can easily see how ridiculous the scaling can get.

Basically a free 50% DMG buff for your active character while Q is active… It’s insanely strong for an off-field buff
So more Elemental Types = More HP for Yelan = More DMG

Unless running a mono-comp (highly ill-advised btw), you’re guaranteed to at least gain the 18% HP Bonus since the average comp always utilizes an Anemo/Pyro buffer + Electro/Cryo/Pyro DPS for Elemental Reaction DMG.

Talent Leveling Order: Q > E > Normal (Don’t really need to level NA)

I want to make this EXTREMELY clear: Building ATK%/ATK on her is effectively useless and does SQUAT for her. Her scaling is entirely based on HP!

WEAPON #1 (Recommended for Best DPS): Aqua Simulacra

How do I get it D: ? – It’s time to roll boys (gacha)

Has base CRIT DMG scaling and provides a ton of easy DMG buffs!

Aqua Simulacra is an extremely straightforward weapon for Yelan. It’s her BiS due to 1) the additional 16% HP increase and 2) the free 20% DMG with basically a permanent uptime. Since both Yelan’s E and Q scale off her Max HP, the 16% HP increase is huge to providing additional damage. Since Yelan’s Q is dynamic, it means that the 20% DMG buff will be consistently applied to her Q (assuming the on-field character is near enemies). If you’re struggling with energy, then you can opt for an ER% Sands if you have Simulacra — otherwise stick to HP%

Elegy For The End is also a great option as it provides decent ER% and EM for Yelan. Although energy generation isn’t Yelan’s largest issue (since her E is only 10s CD) and her burst is only 70 cost, the ER% Elegy provides can allow for higher Q uptime. The 160 EM provided is also great since Yelan will be the one who proc’s the elemental reactions (similar to Xingqiu’s Q). Elegy’s effect will trigger with a single Q, and will gain the buffs since it’s not snapshotted.

Polar Star may seem nice for it’s passive E and Q buffs, but the effect is genuinely useless for Yelan as her abilities purely scale off Max HP – so the ATK buff from Ashen Nightstar stacks are essentially useless.

WEAPON #2 (Recommended for 4-star DPS): The Stringless

How do I get it D: ? – It’s time to roll boys (gacha)

Has base EM scaling and provides free E and Q buffs!

Stringless is a staple for off-field buffs as the E and Q DMG buffs are always applied. The EM it provides is also great for Yelan as she’ll be constantly proc’ing elemental reactions with her Q. Stringless at R5 will also tend to outperform Elegy at R1, so it’s a solid option to run on Yelan.

Alley Hunter at R5 can compete somewhat with Stringless, but regarded as a second pick due to possible downtimes of the buff. If you utilize Yelan’s E and then Q afterwards, the 4s will pass and Yelan will have a short second of lowered buffs – albeit not a huge issue as the DMG stacks will eventually climb back to full. However the ATK% it provides is useless, so it’s secondhand to Stringless

Recurve Bow while being a 3-star weapon that doesn’t provide a useful weapon skill, the raw HP% bonus it provides at max level (46.9%) is insanely good as a placeholder. It’s basically a free additional HP artifact slot, which provides an ample amount of DMG to Yelan’s E and Q. If you somehow don’t have any of the aforementioned weapons, Recurve Bow can definitely come in clutch.

Energy Recharge may be necessary if you don’t have optimal substats, so Favonius Warbow will provide a ton good ER%. The event bow, Fading Twilight, is also a good placeholder but the buff rotates — meaning you will have mismatched DPS output with sub-optimal ER%.

ARTIFACT(S) (Recommended for Best DPS): Heart of Depth + Tenacity of the Millelith

How do I get it D: ? – Peak of Vindagnyr Domain (AR 30 locked, 20 Resin per run) and Ridge Watch Domain (AR 30 locked, 20 Resin per run)

Boosts everything
Boosts E and Q

2x Heart + 2x Millelith is an optimal loadout for Yelan as it provides both 15% Hydro DMG bonus and some additional HP to boost her abilities. If you don’t care too much about on-field capability and want to run her purely burst off-field, then replace Millelith with 2x Noblesse. Otherwise, in total DPS output, the Heart + Millelith combo has a bit more output.

An alternative set can be 4x Emblem of Severed Fate as it provides good ER% and the 4x bonus can be amazing. However this set does require a bit more optimization in artifacts as you need to balance both high CRIT values as well as HP and ER%. If you are able to godroll, then overall 4x Emblem will outperform, but keep in mind that running an ER% Sands > HP% Sands is not a viable option.

Early on you can run 2x Adventurer + 2x Instructor or just opt for full 4x Exile. The first set combination just allows for a tiny bit more DMG output, but you will struggle to maintain energy. Second set is vice versa: more ER% with the tradeoff for tiny bit more DMG.

Main stats:

HP% (ER% if running Simulacra)Hydro DMG%CRIT DMG

Substats: CRIT DMG > CRIT% > HP% > ER% > Flat HP

If you want other characters let me know. Hope this helped. Bye.


I spend too much time filling out spreadsheets for incoherent data, but at least I can turn them into guides :P

  1. I disagree with you on the best weapon/Artifact.
    I think c0 Yelan, Still R1 Favonius Warbow + 4x Emblem of Severed Fate is better.
    Because Yelan c0 lack of ER%, Favonius Warbow can provide a wealth of ER%(And it’s for the whole team).
    Its a great weapon on many late game teams for my support characters.
    ER180% of 4x EoSF + Hydro DMG% = Q Additive DMG91.6%, so R5 The Stringless (Additive DMG45%) and Favonius Warbow.
    Heart of Depth(15) + Tenacity of the Millelith(20%HP) + R5 The Stringless(48) +Hydro DMG%(46.6) is about 115%.
    Elemental Mastery for Yelan Not much improvement,because for Hydro char basically useless.
    Only whale’s c6 Yelan then need The Stringless,But they will only pull Aqua Simulacra, so Stringless looks like amazing data, but the cost is very high(need R5), the benefit is not much higher than 4xEoSF.
    Because this 180ER% is easy to get, and we often for Xiangling /Raiden farm 4x EoSF, It’s actually not that hard to come up with good statistics.
    so i use R1 Favonius Warbow + 4x Emblem of Severed Fate.
    c6’s whale use Aqua Simulacra.
    My language is a bit confusing, But thank you for the explanation:)

    • In my experience, you’re describing the other side of the same coin. A lot of it comes down to your artifact rolls. I don’t have Aqua Sim, but I have experimented a lot with everything else mentioned here. In my case, I ended up doing my best damage with Stringless and EoSF thanks to some great rolls on Emblem pieces. I think that as long as your ER is fine, then you have leeway with artifacts depending on how your luck goes. A Heart of Depth + Millelith or Noblesse combo might be much easier for some people to get and will probably perform just as well unless you have some really sick rolls on Emblem pieces. *shrug*

      • Reply after two months 🙂 I use HP% Eon, Hydro DMG% Eonothem, CRIT DMG Logos, because the HP must be over 30,000, otherwise the DMG’s Multiplication interval will be out of balance. It is true that you can use whatever you have, and the 2+2 combo is quite good, but you need Hydro DMG% Eonothem, if you use HP% Eon, the DMG Multiplication interval will also be unbalanced, and the DMG will be much lower.
        C0 use Favonius Warbow + 4x Emblem,C1 use The Stringless + 4x Emblem(or better 2+2 combo).
        Artifacts farming is HARD, I still haven’t improved the statistics of Yelan until now……..
