Light Cone
In the Name of the WorldIts Effect Hit Rate and direct bonuses against debuffed targets make it Welt's signature damage-oriented alternative.
When to use it : Keep the target debuffed before Welt attacks.
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.
Before the Tutorial Mission StartsAgainst DEF-reduced enemies, its Energy return shortens Welt's Ultimate cycle and supports the fast debuff rotation.
A four-star Herta Store cone available without a limited signature.
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.
Planar Ornaments
Energy regeneration helps maintain the Ultimate's delay and DEF reduction, while the first-slot Ashveil receives its ATK 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.
