Slow down your opponents with the best Honkai: Star Rail Welt build and gain a huge tempo advantage for your team. Welt, who is also known as Mr. Yang to the crew of the Astral Express, follows the Path of The Nihility and deals Imaginary DMG.

Welt’s Skill, Edge of the Void, deals Imaginary DMG based on his ATK to a single target, and then randomly damages two additional targets. Each hit has a chance of reducing the enemies’ SPD, potentially slowing down their next action and shuffling the turn order.

His Ultimate, Synthetic Black Hole, deals Imaginary DMG to all opponents based on his ATK and is guaranteed to trigger the Imprisoned effect, which delays the target’s actions as well as reducing their SPD. Welt’s Talent, Time Distortion, helps him maximize his damage output by adding extra Imaginary DMG to hits against enemies that have been slowed.

Welt’s Eidolon Levels, which get upgraded when you pull duplicates of him, focus on enhancing his damage output further. Level 1 enhances Welt’s next two Basic Attacks or Skill uses after he uses his Ultimate, allowing them to deal extra damage. Level 2 restores his Energy when Welt’s Talent is triggered. Level 4 increases the base chance to decrease the SPD of targets hit by his Skill, while Level 6 adds another randomly targeted hit to his Skill.

Honkai: Star Rail – Welt: best Light Cones

Welt has a signature Light Cone in Honkai: Star Rail, which goes by In the Name of the World — a little play on words here, as Welt simply means “world” in German. That aside, this Light Cone increases the wearer’s damage against debuffed targets significantly. It enhances their Skill as well, adding Effect Hit Rate and ATK boosts.

This allows Welt to apply his debuffs more consistently and add even more damage to targets he’s slowed down.

Best Light Cones for Welt in HSR:

  • In the Name of the World (5-Star)
  • Along the Passing Shore (5-Star)
  • Incessant Rain (5-Star)
  • Boundless Choreo (4-Star)
  • Good Night and Sleep Well (4-Star)
  • It’s Showtime! (4-Star)

Honkai: Star Rail – Welt: best Relics

Welt is a difficult one to pin down: He somehow wants more of everything. Effect Hit Rate is vital to fulfill his role of a debuffer, while ATK, CRIT Rate, and CRIT DMG are needed to maximize his damage output. At the same time you can’t neglect Welt’s SPD, letting him fall behind. Then you want Energy Regeneration to help him charge his useful Ultimate as well — it’s a challenge.

Best Relic Sets for Welt in HSR:

  • Pioneer Diver of Dead Waters (4) – +12% damage against debuffed enemies, +4% CRIT Rate, +8%/12% CRIT DMG against enemies with at least 2/3 debuffs; these effects are doubled for one turn when the wearer inflicts a debuff on an enemy.
  • Wastelander of Banditry Desert (4) – +10% Imaginary DMG, +10% CRIT Rate, +20% CRIT DMG when attacking Imprisoned enemies.

Honkai: Star Rail – Welt: best teams

Welt is in a weird spot, as his greatest ability – slowing enemies down – isn’t really wanted or needed by many teams. As someone focusing on debuffs, there are still roles for him to play, though.

  • Acheron (Main DPS), Welt (Sub DPS), Pela (Support), Aventurine (Support)

Welt has the necessary kit to complement Acheron, generating charges for her Ultimate by inflicting debuffs on enemies alongside Pela and Aventurine — the latter being charged with keeping the team healthy as well. Another Main DPS benefitting from Welt’s presence is Dr. Ratio, who also wants his enemies debuffed to make the most use of his own abilities.

Honkai: Star Rail – Welt: ascension materials

Here’s everything you need to know to get Welt ascended to the maximum level and upgrade all of his talents.

Welt requires the following ascension materials to get to level 80 in addition to the necessary XP:

  • Credits x308,000
  • Silvermane Badge x15
  • Silvermane Insignia x15
  • Silvermane Medal x15
  • Golden Crown of the Past Shadow x65

You can collect Silvermane Badges, Insignia, and Medals from enemies in the Outlying Snow Plains or the Corridor of Fading Echoes as well as the Simulated Universe. You can create or exchange them through the Omni-Synthesizer on the Astral Express, too. Silvermane Badges are one of the base materials you can easily farm through the Daily Assignments to your characters, making for a steady income of the material. Golden Crowns of the Past Shadow are dropped by the Stagnant Shadow (Backwater Pass) or gained through the exchange of similarly rare materials. The best source of Credits are the Golden Calyxes found around the universe.

Welt requires the following materials to upgrade her combat abilities and Traces:

  • Credits x3,000,000
  • Silvermane Badge x41
  • Silvermane Insignia x56
  • Silvermane Medal x58
  • Obsidian of Dread x18
  • Obsidian of Desolation x69
  • Obsidian of Obsession x139
  • Destroyer’s Final Road x12
  • Tracks of Destiny x8

For the materials already mentioned, check above. Obsidians can be farmed in the Crimson Calyx (Great Mine). As usual, you can create the high-level materials by using lower-level materials in the Omni-Synthesizer on the Astral Express.

Destroyer’s Final Road is a boss material only gained from the Echo of War (Supply Zone) domain, while Tracks of Destiny can be obtained during time-limited events, the Embers Exchange, the Nameless Honor, or as a Simulated Universe Points Reward.
