HSR Simulated Universe Guide: Best Tips, Paths, and Team Builds

Mastering the Simulated Universe is the most effective way to secure weekly Stellar Jades and high-tier Planar Ornaments for your characters. This rogue-like game mode rewards strategic planning, Path selection, and a deep understanding of how Blessings interact with your team’s specific mechanics.

Overview

The Simulated Universe (SU) serves as Herta’s testing ground, offering a rogue-like experience where Trailblazers navigate through various Domains to face a final Boss. Success in the SU relies less on raw character stats and more on the synergy between your team and your chosen Path. As you progress, you collect Blessings and Curios that provide massive buffs, often turning even modest teams into unstoppable forces.

Clearing the Simulated Universe is a core part of the endgame loop. Weekly resets provide Herta Bonds, which are used to purchase 5-star Light Cones, along with Trailblaze EXP and Star Rail Passes. Furthermore, the SU is the only source for Planar Ornaments, the two-piece accessory sets that define a character’s endgame build.

Understanding Path Resonance

When you collect three Blessings of your chosen Path, you unlock Path Resonance. This is a powerful active ability that can be manually triggered during combat. As you collect 6, 10, and 14 Blessings of that same Path, you can choose Resonance Formations to further enhance the ability, such as increasing its damage, allowing it to regenerate energy faster, or adding secondary status effects.

The Importance of the Ability Tree

The Ability Tree provides permanent, account-wide upgrades that apply only within the Simulated Universe. These nodes increase your characters’ HP, ATK, and DEF, and unlock critical mechanics like the ability to carry more Cosmic Fragments or increasing the appearance rate of high-rarity Blessings. If you find yourself struggling with World 6 or higher, spending time farming lower worlds to max out your Ability Tree is the most reliable way to increase your power.

Blessings vs. Curios: What to Prioritize

Blessings are the primary source of your power. They provide direct combat buffs like increased Critical Damage, Speed, or specialized effects like “Aftertaste” or “Quake.” Curios, on the other hand, are artifacts that provide utility or high-risk/high-reward modifiers.

Generally, you should prioritize Blessings that match your Path to unlock Resonance Formations as early as possible. However, if a Curio like the “The Doctor’s Robe” (which increases Path Resonance damage and starts every battle with full Resonance Energy) appears, it is often worth taking over a single Blessing.

Path	Primary Combat Focus	Key Mechanic
Preservation	Defense and Shielding	Quake Damage (Damage based on Shield strength)
Remembrance	Freezing and Crowd Control	Dissociation (Percentage-based HP damage on frozen foes)
Nihility	Damage over Time (DoT)	Suspicion (Increased DoT damage taken)
Abundance	Healing and Sustainability	Dewdrop (Accumulated healing released as damage)
The Hunt	Speed and Critical Hits	Critical Boost and Turn Reset
Destruction	High Risk, High Reward	Fighting Spirit (Stat boosts when HP is low)
Elation	Follow-up Attacks	Aftertaste (Additional damage on follow-up hits)
Propagation	Basic ATK and Skill Points	Spores (Explosive damage from Basic Attacks)
Erudition	Ultimate Damage and AoE	Synapse Resonance (AoE damage triggered by Ults)

Best Weapons

The Simulated Universe features its own economy through Herta’s Store. By earning Herta Bonds from weekly rewards and first-time World clears, you can purchase and superimpose 5-star Light Cones. These weapons are often comparable to signature gacha weapons and are essential for F2P (Free-to-Play) players.

Top Herta Store Light Cones

Herta’s Store currently offers five primary 5-star Light Cones. Each corresponds to a specific Path and serves as a “best-in-slot” F2P option for many top-tier carries.

Light Cone	Path	Key Effects	Best Characters
On the Fall of an Aeon	Destruction	Increases ATK by up to 16% (S1) / 32% (S5) when attacking. Increases DMG after Breaking Weakness.	Jingliu, Firefly, Dan Heng • Imbibitor Lunae
Cruising in the Stellar Sea	Hunt	Increases Crit Rate. Increases Crit Rate further against enemies with low HP. ATK buff on kill.	Seele, Feixiao, Yanqing
Texture of Memories	Preservation	Increases Effect RES. Grants a Shield when hit if the wearer has no shield. Reduces DMG when shielded.	Fu Xuan, Fire Trailblazer, Gepard
Solitary Healing	Nihility	Increases Break Effect. Increases DoT dealt for 2 turns after using Ultimate. Regenerates Energy when DoT kills.	Kafka, Black Swan, Sampo
Eternal Calculus	Erudition	Increases ATK. After hitting enemies, gains more ATK (stacks). Increases SPD when hitting 3+ enemies.	Himeko, Herta, Argenti

Best Gacha Alternatives for SU Carries

While Herta’s weapons are excellent, certain gacha Light Cones excel specifically within the SU due to the abundance of buffs. For example, “Along the Passing Shore” (Acheron’s signature) is devastating because the Nihility Path Blessings amplify the debuffs she applies. “Baptism of Pure Thought” (Dr. Ratio’s signature) scales incredibly well with Elation Blessings, as the Path provides the follow-up frequency needed to maintain the weapon’s buffs.

Best Disks (Artifacts)

In Honkai: Star Rail, “Disks” refers to the Relic system. Specifically, the Simulated Universe is the exclusive source for Planar Ornaments, which consist of the Planar Sphere and Link Rope. These sets provide powerful 2-piece bonuses that often define a character’s role.

Top Planar Ornaments for DPS

For damage dealers, the choice of Planar Ornament depends on where their primary damage comes from (Ultimate, Follow-up, or Basic ATK).

Inert Salsotto (World 6): Increases Crit Rate by 8%. When Crit Rate reaches 50% or higher, Ultimate and follow-up attack DMG increases by 15%. This is the premier set for characters like Dr. Ratio, Topaz, and Aventurine.
Rutilant Arena (World 7): Increases Crit Rate by 8%. When Crit Rate reaches 70% or higher, Basic ATK and Skill DMG increase by 20%. This is the go-to for Dan Heng • Imbibitor Lunae and Jingliu.
Firmament Frontline: Glamoth (World 8): Increases ATK by 12%. When SPD is 135/160 or higher, the wearer deals 12%/18% more DMG. This is excellent for high-speed DoT characters like Kafka or Break DPS like Firefly.

Best Support Sets for Simulated Universe

Supports need sets that provide team-wide utility or increase their own survivability to ensure the team survives high-difficulty boss phases.

Broken Keel (World 7): Increases Effect RES by 10%. When Effect RES is 30% or higher, all allies’ Crit DMG increases by 10%. This set stacks, meaning if three supports wear it, the main DPS gains 30% Crit DMG.
Fleet of the Ageless (World 3): Increases HP by 12%. When SPD is 120 or higher, all allies’ ATK increases by 8%. Standard for healers like Huohuo or Lynx.
Lushaka, the Sunken Seas undisclosed: While newer worlds continue to expand the roster, always look for sets that provide Energy Regeneration Rate (ERR) for your Harmony characters.

Farming Priority: Which Worlds to Grind First

If you are just starting your endgame journey, prioritize World 7. Both Rutilant Arena and Broken Keel are “universal” sets that fit a vast majority of the cast. After that, World 6 is vital for follow-up attackers (Inert Salsotto), and World 3 (Fleet of the Ageless) is the most efficient for building up your early-game healers.

Team Comp

Building a team for the Simulated Universe is different from building for Memory of Chaos. In SU, you should pick characters that can maximize the “gimmick” of a specific Path.

The Nihility DoT Powerhouse

The Nihility Path relies on Damage over Time (DoT) and debuffs. It is currently one of the most consistent ways to clear high-difficulty content because the Path Resonance deals massive damage based on the number of DoT stacks on the enemy.

Premier Team: Kafka (Enabler), Black Swan (DoT/Debuff), Acheron (DPS), and Huohuo or Aventurine (Sustain).
F2P Alternative: Sampo, Guinaifen, Serval, and Lynx.

Elation: The Follow-Up Meta

The Elation Path turns follow-up attacks into tactical nukes. With the “Aftertaste” mechanic, every follow-up attack triggers additional instances of damage of different types.

Premier Team: Topaz & Numby, Dr. Ratio, Robin, and Aventurine.
F2P Alternative: Herta, March 7th, Dr. Ratio, and Natasha.

Hypercarry Teams for The Hunt and Erudition

The Hunt is ideal for single-target bosses, while Erudition (unlocked via Gold and Gears) is built for Ultimate-heavy AoE damage.

Hunt Team: Seele, Bronya, Tingyun, and Fu Xuan.
Erudition Team: Argenti, Jade, Ruan Mei, and Huohuo.

F2P-Friendly SU Teams

If you lack limited 5-star characters, the Preservation Path is your best friend. By using the Fire Trailblazer and March 7th together, you can stack massive shields that trigger “Quake” damage through Preservation Blessings, allowing your team to deal damage simply by being hit.

Rotation

In the Simulated Universe, your rotation isn’t just about character skills; it’s about the timing of your Path Resonance and the management of your resources.

Optimizing Path Resonance Timing

Don’t simply fire off your Path Resonance as soon as it’s available.

Phase Transitions: Bosses in SU have multiple HP bars. If a boss is at 5% HP, do not use your Resonance. Wait for the next phase to start so the Resonance damage isn’t wasted on a nearly dead enemy.
Add Clearing: Many bosses, like Cocolia or the Swarm: True Sting, summon smaller adds. Use Path Resonances like The Hunt or Erudition specifically to clear these adds instantly, keeping the focus on the main boss.
Resonance Formation: Anatta (Abundance): This formation puts the Path Resonance on the Action Bar, causing it to heal and cleanse your team automatically. This is vital for bosses that apply heavy CC (Crowd Control) like Kafka’s Dominate.

Blessing Synergy: Combining Paths

The best runs often involve “Interplay” or simply picking high-value Blessings from outside your main Path.

The “Hell is Other People” (Nihility): Even if you aren’t on the Nihility Path, this 1-star blessing spreads Weakness Break to adjacent enemies, which is incredibly useful for any team.
Destruction’s “Regression Inequality of Annihilation”: This 3-star Blessing distributes damage taken among all allies. This prevents your squishy DPS from being one-shot by boss ultimates.

Curio Management Strategy

Manage your Cosmic Fragments wisely. In the final Respite room before the boss, you have the option to enhance Blessings. It is almost always better to enhance three 3-star Blessings than ten 1-star Blessings. Focus on enhancing the “Blue” and “Gold” Blessings that provide multiplicative bonuses or change how your Path Resonance functions.

FAQ

How do I get more Herta Bonds? Herta Bonds are earned by clearing a World for the first time at any difficulty level. Additionally, you earn them by reaching the weekly score limit in the Simulated Universe (the “Weekly Reset”).

What is the best Path for beginners? The Abundance is the safest Path for beginners. It provides constant healing and cleansing, which compensates for lower-level gear. If you have a strong shielder like Gepard, the Preservation Path is also extremely safe.

How do I unlock the Propagation and Erudition paths? The Path of Propagation is unlocked by completing all chapters of the Swarm Disaster DLC. The Path of Erudition is unlocked by progressing through the Gold and Gears DLC. These are permanent expansions to the Simulated Universe.

Should I choose Combat or Occurrence domains? Early in a run, choose Combat domains to guarantee Blessings and build your Resonance. In the middle of a run, Occurrence domains are better as they offer a chance at powerful Curios or rare events (like the Ruan Mei event which grants all Blessings of a Path). Use Gush undisclosed or similar mechanics in DLCs to skip unnecessary fights if your build is already strong.
