The Simulated Universe in Honkai: Star Rail isn’t just another feature-it’s a challenging maze of choices, blessings, and cosmic chaos. This guide breaks down how to build winning runs, make the right path decisions, and turn randomness into your strongest ally.
There are six Worlds to clear, which unlock as you both progress through story and beat the World that came before it.
How to get rewards in Simulated Universe
To earn rewards in Simulated Universe, complete daily and weekly tasks, chase high-difficulty runs for bigger drops, and invest the right relics and team compositions to maximize rewards from your chosen paths.
Simulated Universe is a prime location to get Planar Sphere and Link Rope relics, as you’ll find them as rewards from beating bosses and elite monsters. We started getting these relics as rewards during our runs of World 3.
The gist of it is explained in-game as you go and find more things (Herta is pretty good at explaining things step-by-step). However, if you skipped all her dialogue, here’s a gameplay explainer:
- Each room you enter will either have enemies or an event. Some rooms can have both.
- Every time you beat an enemy, you’ll be able to select one of three buffs that appear. These buffs last in that run of the World only. The buffs can be upgraded using in-universe currency.
- Events can give you buffs, in-universe currency, or other rewards. Not all events are beneficial.
- You’ll also sometimes find Curios, which are buffs that are permanent within Simulated Universe.
- Once you clear the room of events or enemies, you can proceed through a door to a new room. Sometimes there are multiple doors, so you can choose where to go.
- You’ll get a heads up about what’s waiting for you in the next rooms, as the doors will be labeled as “combat” (enemy), “elite” (harder enemies), “boss,” or “occurrence” (event).
- You cannot heal using food while in the Simulated Universe.
- As you make it through Simulated Universe, you’ll get Ability Points, which you can put into a skill tree that only applies within the universe.
- If your party dies in Simulated Universe, you’ll have to start that World over again.
You will essentially want to make sure to run Simulated Universe every week to get Stellar Jade and decent rewards. Pick buffs that suit your party and smash through as many enemies as you can. (For example, if you’re not running a character who can freeze enemies, you probably should not pick buffs that do more damage to frozen characters.)
Best team compositions for Simulated Universe Worlds
Honkai: Star Rail’s Simulated Universe features randomized runs where flexible teams emphasizing sustain, weakness breaks, and Path synergies shine across Worlds. Optimal comps adapt to blessings, Curios, and enemy weaknesses, prioritizing shields/heals early and DPS ramps later.

Best F2P teams for Simulated Universe Worlds
