Welt is a Support unit that is capable of dealing a decent amount of Toughness DMG and can Slow enemies down. He can also delay an enemy's turn using his Ultimate, giving more chances for your other units to attack them.
After his Novaflare buff in Version 4.2, he can now apply Weightless onto his enemies. Weightless delays their actions even further, reduces their DEF, and increases the damage they take. This debuff alone makes Welt worth building as a support or a DPS.

Welt's Support build focuses on the Weightless debuff. It's important to get Effect Hit Rate stats, so that Welt can apply his debuffs without difficulty.
As for Relics, Eagle of the Twilight Line is his best-in-slot as a support since it advances his turn forward whenever he uses his Ult, which means more frequent debuff application. Lushaka is the general go-to for all Support units, and since Welt's best teams usually have the Main DPS scale on ATK.
| Stat | Recommended Value |
|---|---|
| SPD | 135 - 160+ 170 with Lies Dance on the Breeze |
| Effect Hit Rate | 75% or above |
For Welt to consistently apply his debuffs, he would need 75% Effect Hit Rate for guaranteed application. Any amount of SPD above 135 will do for Welt, but do keep SPD Breakpoints in mind.

With the buffs from Version 4.2, Welt can now be played as an Imaginary Main DPS who can deal a lot of damage through his abilities while still inflicting his debuffs onto the enemy.
Pioneer of Dead Waters is Welt's best Relic set since it allows him to deal more damage to enemies with debuffs, along with getting a boost to CRIT stats. Pan-Cosmic is still the best Ornament set for him since it gives him Effect Hit Rate and increases his ATK, which allows him to get more value from his Bonus Ability's new conversion.
Those Many Springs give him a lot of Effect Hit Rate while also inflicting an additional debuff on the enemy to increase the damage they take.
| Stat | Recommended Value |
|---|---|
| SPD | 135 / Base SPD (With Turn Advancer) |
| ATK% | 2500 or above |
| CRIT Rate | 90% or above (In Combat) |
| CRIT DMG | 120%+ (Before Combat) |
| Effect Hit Rate | 80% or above |
As a main DPS, Welt needs enough crit stats to reliably output his damage. He also needs 135 SPD to get two actions in one cycle, and can run at base SPD when he's with a turn advancer like Sparkle.
The max ATK conversion from his new Bonus Ability is capped at 80% Effect Hit Rate, so try to reach that with relic substats if possible. It should be easy to reach if you're running a Light Cone that gives him Effect Hit Rate as well.

| Ultimate | Ultimate now applies Weightless to enemies, delaying their actions further when they get attacked. |
| Talent | Now reduces the DEF of enemies under the Weightless state. |

| Bonus Ability - Punishment | Converts extra Effect Hit Rate over 40% into ATK. The max boost Welt can get from this is an 80% ATK boost. |
Welt's Ultimate now applies Weightless to enemies after he uses it, which delays their actions whenever they get hit.
Welt's Retribution Bonus Ability increases the damage enemies take when they're attacked under the Weightless state. This also stacks and can ramp up quickly with multiple attacks.
Welt's Talent also now reduces the DEF of enemies when they're in the Weightless state.
Welt's Punishment Bonus Ability will now convert excess Effect Hit Rate into ATK. This caps at an 80% ATK boost.

Welt's Skill will bounce off multiple enemies, which means if you are facing multiple enemies he could easily Weakness Break with Imaginary.
Something to note about moves that deal extra damage to random enemies is that in Single Target situations, the attack all focus on the single remaining enemy, making it easier to Break its Toughness bar.

Welt can turn the tide of battle by slowing and delaying enemies. You can use this efficiently by using his Ultimate during the enemies' turn to have your characters move ahead.
Welt's Ultimate allows him to apply Weightless onto his enemies. This delays their actions even further when they hit, and his Talent also reduces their DEF when in this state. It also gives a stacking damage increase against enemies.

You can use Welt's Technique to inflict Imprison on enemies before a battle starts. This will affect all enemies in combat.

He must reach 80% effect hit rate to get all the bonuses and proc the debuffs. His traces now give him 28%, compared to the 0% from before. Very challenging build too. I'm curious about how he will be in this super toxic meta full of whales forced spending by hoyo. 4.0 was the last honest anomaly arbitration imho
