Light Cone
Lies Dance on the BreezeAt 170 SPD, Welt activates the cone's second DEF-reduction effect and maintains fast, teamwide support through frequent attacks.
When to use it : Welt must have at least 170 SPD out of combat.
Resolution Shines As Pearls of SweatIts attack-applied DEF reduction supports the same fast debuffer role, but has a shorter duration and needs more Effect Hit Rate at low Superimposition.
A four-star permanent Warp cone that avoids a limited five-star signature.
Good Night and Sleep WellGood Night and Sleep Well converts every debuff on the target into more personal damage, including damage over time.
When to use it : Use in teams that reliably keep three debuffs on the target.
Relics
With an Ultimate every two to three actions, the action advance produces more turns, debuffs and Energy than a conventional damage set for support Welt.
Two-piece Messenger Traversing Hackerspace plus two-piece Guard of Wuthering Snow is a transition mix: Increases SPD by 6%. Reduces DMG taken by 8%.
It reuses strong pieces from two sets while a complete four-piece configuration with equivalent main stats and substats is still being farmed.
Planar Ornaments
Energy regeneration helps maintain the Ultimate's delay and DEF reduction, while the first-slot Ashveil receives its ATK bonus.
Broken Keel is a ranked alternative with this two-piece effect: Increases the wearer's Effect RES by 10%. When the wearer's Effect RES is at 30% or higher, all allies' CRIT DMG increases by 10%.
When to use it : Reach 30% Effect RES to activate the teamwide CRIT DMG bonus.
Team lineup
Ashveil rewards frequent allied attacks and layered debuffs, Welt supplies both, Sunday adds actions and Energy, and Aventurine sustains while attacking often.
Trace priority
- Ultimate
- Talent
- Skill
Welt slows targets, delays their actions and uses his Ultimate to impose Imprisonment and teamwide DEF reduction while still contributing damage.
How to play it
- 1Attack to establish the cone's DEF reductions before allied damage lands.
- 2Use the Skill when its multi-hit Slow and Energy are worth a Skill Point; otherwise use Basic ATK.
- 3Cast the Ultimate immediately after an enemy finishes its turn to maximize the distance of the delay.
Sources and methodology
Editorial recommendations are written from released game data, then cross-checked against specialist calculations. They are not copied from a single tier list.
Review method
Prydwen's 4.2 support calculations and Icy Veins' Novaflare analysis agree on fast debuff Welt. The broader released 4.0–4.4 compare and exact 4.4 data confirm Lies Dance's 170-SPD condition and the revised kit. The target assumes 80% sheet Effect Hit Rate, not an unlisted external buff.

Independent fan recommendations based on released data. Delaying enemies can reduce ally mechanics that require enemies to take turns; time the Ultimate deliberately.
