Edited: updated calculations for 1-5 targets. Added the 4* Choreo LC.
Hello Everyone!
I have been calculating some E6 Welt mainDD to find which LC to give to him. This is just my findings, but I do not claim everything to be as precise to the point. I am open for discussion, and I hope you find it interesting.
First of all, I included his signature and SIlver Wolf's LC S1-S5 because they are available in the shop/you can lose to his LC, too.
I was specifically looking for Crit damage heavy teams (Sparkle + Sunday + DHPT). As it was already discussed in another post, if your Welt is E6 but you build him with a lot of crit damage it makes sense to rich closer to 100% crit rate (it will give his skill and ultimate hits 130% crit rate and +60% crit damage, but compared to 400-500% crit damage he gets from supports, you better make sure additional hits crit).

Notes
Signature S2 is taken as a reference because it's what I currently have.
Silver Wolf's LC loses its position when the number of enemies increases as it requires all the hits from skill land on the same target where Aether Code is applied.
JIAOQIU S1 #1 IN ALL SCENARIOS
The only LC giving a fully multiplicative damage term on top of everything else. the LC's +60% EHR fills the entire EHR slot requirement with zero subroll investment, freeing all 21 non-CR subs for CD. The combination of maximum ATK (A6=80% perm), maximum CD, AND extra vulnerability simultaneously places it ahead of every other option. Grows slightly stronger with more enemies as both Ult AoE and vulnerability scale together.
SW LC - WHY EACH COPY MATTERS AND WHERE COPIES STOP MATTERING
Every SW LC superimposition grants enough permanent EHR (24–40%) that only 5–10 additional EHR subrolls are needed to reach A6=80% on all hits. This unlocks the same high ATK floor as Jiaoqiu while freeing the remaining budget for CD. The LC also provides conditional +12–20% CRIT Rate, reducing the CR subroll requirement to just 2–5 subs.
The difference between copies is almost entirely Aether Code (12% at S1 → 20% at S5). Code fires after each action and applies to the next action's hits on the same enemy. Against one target: full benefit, +10–15% on Skill hits. Against 3 targets: only ⅓ of hits land on the coded enemy → Code benefit drops to ⅓. Against 5: ⅕. This is why SW LC S5 leads by 15.2% in N=1 but only 12.1% in N=5 — and also why S1 vs S5 gap is only ~10% in N=1 but essentially zero in N=5.
What makes Acheron LC interesting is +36% CD bonus. Since the LC pre-loads 36% CD, additional CD subrolls become less valuable. all 18 non-CR subs go into EHR instead, reaching A6=80% permanently (80.7% EHR) with 5372 ATK on all hits. This is actually higher permanent ATK than most Sig LC builds.
The +24% Ult DMG bonus hits every enemy the Ult reaches N=1: +6.3% over Sig S2, N=3: +8.8%, N=5: +9.4%. This is the clearest example of an AoE-scaling LC in the list.
HOLIDAY S5 - 4*
Like Acheron LC, all non-CR rolls into EHR (18 subs → A6=80% permanently). The combined vulnerability is a gain on every single hit of every ability. This matters most when Welt's own stats are already high.
The 529 base ATK does create a deficit (~400 ATK at this multiplier level). But the vulnerability advantage (+12.3% multiplicative on all damage) more than compensates, resulting in +7.7–8.2% over Sig S2 regardless of enemy count.
WELT SIGNATURE LC - WHY IT'S B TIER DESPITE BEING "THE" DEDICATED WEAPON
The Signature LC's value is exclusively conditional: its ATK boost and EHR bonus only apply during Skill turns. On Ult hits, Basic ATK hits, and all Additional DMG (Talent stacks, A4 Judgment, E1 Legacy of Honor), the LC contributes only its permanent A6 tier and +28% DMG to debuffed.
We spend 11 EHR subs to reach 60.3% EHR → A6=40% permanently, with Skill EHR reaching 81% (S2) → A6=80% on Skills. Going further (13–15 EHR subs) would reach A6=60% permanently but the cost in CD subs outweighs the gain on non-Skill hits.
Why the Signature is B tier in a calculated comparison but can feel stronger in practice: In a real Skill-heavy rotation (with Sunday giving Welt extra actions for Skills), the Skill ATK spike is worth more than a simplified 2S+1U rotation. It also allows to build a "gamble" build with less crit rate, but it makes the output even less consistent.
WHY BOUNDLESS CHOREO S5 RANKS BELOW BASELINE
Choreo's stats look impressive on paper: +16% CR +48% conditional CD (vs Slowed OR DEF-reduced - near 100% for Welt).
But Choreo has 476 base ATK. vs 582 for all standard 5★ LCs, that's 106 ATK less. With 97% external ATK%: That's 534 ATK less, or 15.9% lower ATK permanently.
The CD advantage gains roughly 11.7% on crit multiplier. The ATK deficit loses 15.9%. Net: −4.2%, which is roughly where the 98% index lands. The +16% CR freeing 5 more CD subrolls helps, but cannot close the gap created by the 476 ATK base.
Choreo would only be competitive if Welt had very low external ATK% (e.g., in a team without Sparkle).
