Looking for the best Honkai Star Rail Welt build? Welt is a powerful five-star Imaginary unit that stands alongside some of the best characters in the gacha game thanks to his assortment of potent debuffs. Kit him out with the best build, consider your opponent's elemental weaknesses, and he can bring your opponents to their knees in short order.
Before you can build the best Honkai Star Rail Welt build, you'll need to pull him from Honkai Star Rail.
What is the best Welt build?
The best Welt build is:
- Light Cone – In the Name of the World
- Relics – Wastelander of Banditry Desert
- Planar Ornaments – Talia: Kingdom of Banditry
- Eidolons – Level 1: Legacy of Honor
- Team comp – Welt, Seele, Tingyun, Bailu
As a debuff-oriented character that walks the Nihility path, the best Welt build in Honkai Star Rail is going to build on both his attack, as well as his ability to negatively impact the opposite team. When Welt causes a weakness break, he forces the enemy to miss a turn and reduces their speed, stalling their turn order over the course of battle.
Welt light cones
The best Welt Light Cones are:
- In the Name of the World (five-star)
- Loop (three-star)
- Good Night and Sleep Well (four-star)
The above Honkai Star Rail Light Cones all impact debuffed enemies, which is perfect for this Welt build. In the Name of the World is the best Light Cone for Welt, and increases the damage dealt to debuffed opponents, as well as increasing the effect hit rate and attack of his skill. In lieu of In the Name of the World, though, Loop is a perfect alternative, increasing damage dealt by Welt to a slowed enemy – perfect for when Welt causes a weakness break. Alternatively, Good Night and Sleep Well buffs Welt's damage significantly for every debuff the enemy has.
Welt relics
The best Welt relic is:
| Relic | Effect |
| Wastelander of Banditry Desert (four-piece set) | Increases Imaginary damage by 10%. Plus, when attacking debuffed enemies, Welt's critical rate increases by 10%, and critical damage against imprisoned opponents is buffed by 20%. |
The best Relic for Welt is Wastelander of Banditry Desert as a full four-piece set. The reason for this is its ability to buff Imaginary damage at a two-piece level, but more significantly its effect on imprisoned enemies. When Welt – or another Imaginary on the team – causes a weakness break on an opponent, they are hit with the imprisoned effect. Welt's critical damage against these imprisoned enemies is then increased, all thanks to this Honkai Star Rail Relic.
Best Welt Planar Ornaments
The best Welt Planar Ornament is:
| Planar Ornament | Effect | Sphere | Link Rope |
| Talia: Kingdom of Banditry | Increases Welt's break effect by 16%. When Welt's speed hits 145 or higher, his break effect increases by an additional 20%. | Talia's Nailscrap Town | Talia's Exposed Electric Wire |
On the subject of Welt's weakness break effect, the best Planar Ornament is Talis, Kingdom of Banditry. This Planar Ornament buffs the 's break effect by up to 36%. In Welt's case, this considerably slows the broken enemy down thus forcing them to miss turns, which could be the difference between winning and losing the battle.
Welt Eidolons
The best Welt Eidolon is:
- Legacy of Honor – Level 1: After using his Ultimate, Welt's abilities are enhanced. The next two times he uses his basic attack or skill, he deals extra damage to the target – once each time. For a basic attack, additional damage is equal to 50% of the basic attack damage. For his skill, extra damage is equal to 80% of the skill's damage multiplier.
Luckily for a five-star character, Welt's best value Eidolon is his level one buff: Legacy of Honor. This Eidolon grants boosts to Welt's existing abilities, dealing additional damage when using either a basic attack or his skill, so is particularly useful with the latter, dealing additional damage alongside the debuff to the enemy's speed.
Welt team comp
The best Welt team comp is:
- Welt – Sub-DPS
- Seele – Main DPS
- Tingyun – Buffer
- Bailu – Healer
Welt is a great alternative to Seele thanks to the turn manipulation built into his kit. Welt's capacity to slow enemies is a perfect complement to Seele's own high speed stat, allowing her to sneak in extra attacks while enemies are Imprisoned or simply slowed to a crawl.
Bailu is the optimum healer for this team comp thanks to her ability to revive characters who are downed, which can sustain this team during tough boss battles in Simulated Universe and Echo of War.
Welt ascension materials
Here are Welt's Ascension Materials:
- Silvermane Badge
- Silvermane Insignia
- Silvermane Medal
- Golden Crown of the Past Shadow
Of these materials, the Golden Crown of the Past Shadow is the hardest to farm, only dropped in Stagnant Shadow challenges in the Corridor of Fading Echoes. Meanwhile, the Silvermane items can all also be found in the Corridor of Fading Echoes, dropped by Everwinter Shadewalkers and other area enemies. Silvermane can also be looted from Silvermane Guards in the Outlying Snow Plains.
With this incredible Welt build in Honkai Star Rail, you should see a significant difference in any enemy's ability to fight back, opening up the playing field for you and your team – there's good reason Welt is considered an S-tier character in our characters – but we're not telling you here whether it features Welt or not.
