Honkai: Star Rail – Divergent Universe Guide (2025)

Divergent Universe (DU) is another version of Simulated Universe in Honkai: Star Rail. The game mode is meant to ease the process of Planar Ornament farming, and it also comes with various rewards for players who keep grinding it. Although there’s a timer for the game mode, DU is a permanent content and players don’t need to rush to complete all the tasks. Once the timer ends, the Divergent Universe will expand instead of close.

Although most of the systems in the Divergent Universe are similar to the Simulated Universe and its two spin-offs (Swarm Disaster and Gold and Gears), DU has its own twists that make the gameplay more refreshing compared to existing content. This guide will cover the key information players must know about the Divergent Universe in Honkai: Star Rail.

How To Unlock Divergent Universe

To unlock the Divergent Universe in Honkai: Star Rail, players simply need to clear Simulated Universe: World 3 in Herta’s Space Station. It’s highly recommended to complete Stranger in a Strange Land Trailblaze Mission in Penacony so that Trailblazers won’t lose the immersion, but it’s not a necessity.

If players skip the main quest, they’ll gain access to the areas of Radiant Feldspar that are connected to the Divergent Universe, but they won’t have access to the map, chests, or achievements within.

Planar Ornament Extraction

The key difference between DU and SU lies in the fact that players can "save" a successful Divergent Universe run. After saving the collected Blessings and Curios, they can use the saved data to compose a team to beat a boss of their choice.

Once the boss fell, Trailblazers can claim the Planar Ornament reward using their Trailblaze Power without having to redo the entire Simulated Universe run. So basically, instead of playing SU run every time, players simply need to beat the final boss to get the reward.

Divergent Universe also gives points like normal Simulated Universe, so you can claim your weekly reward through it.

Character Mapping System

Another main feature of Divergent Universe is the Character Mapping system. This mechanic does the following:

• Max a character level.
• Level-up Traces to level 8 (Level 5 for Basic Attack), and activate some of the Skill Tree.
• Assign a Light Cone at max level, if no Light Cone is equipped.
• Boost Light Cone to max level, if Light Cone is equipped.
• Assign suitable Relics at max level, unless the equipped Relics are maxed already.

This allows players to use any character they have without worrying about raising them first. However, this also means players need to be careful as some mapping will mess up their SPD tuning. For example, if Trailblazers make their Sparkle slower than Acheron with their normal Relics, character mapping may mess this up and make Sparkle faster instead​​​​​​.

Additionally, unlike in Simulated Universe, players can freely change their team in the Divergent Universe run without having to use the "Download" machine. Divergent Universe also doesn’t end if players lose a fight; it allows you to restart a challenge, even allowing you to change the team before restarting.

Ordinary & Cyclical Extrapolation

When starting the Divergent Universe, players will see two options; Ordinary Extrapolation and Cyclical Extrapolation.

Ordinary Extrapolation is the "basic" version where players can unlock new difficulties to test their limits. Meanwhile, Cyclical Extrapolation is a weekly-challenge that gives extra rewards for the first weekly clearance. This version follows the highest difficulty you've reached in the Ordinary Extrapolation.

Equation System

Another key difference in the Divergent Universe is the Equation mechanic. Unlike in the Simulated Universe where you follow one Path and you must collect Blessings for that specific Paths, the DU is heavier on RNG with its Equation system. Basically, here’s how it works:

• Players choose between available Equations.
• Each Equation has its own Blessing requirements.
• Players must collect a number of Blessings based on the Equation’s requirements.
• Once you collect the minimum number of Blessings, the Equation will be activated.

Trailblazers can also get the "Path Resonance" in DU, but it’s renamed to Boundary Equations. To get it, you must unlock the correct Node in the Inspiration Circuit, then obtain 16 of the respective Path’s Blessing.

New Items

Other than the aforementioned information, Divergent Universe in Honkai: Star Rail also comes with revamped Occurrence and Blessings, more diverse Domain options, new Interactables, Curio, and Weighted Curio.

One of the most important changes is the existence of the Workbench of Creation. Unlike in Simulated Universe where you can only upgrade your Blessing before the final boss (by speaking to Herta), in Divergent Universe, you can do your upgrade each time you see a Workbench of Creation.

Workbench of Creation appears in certain domains, but it’s guaranteed to appear with a boss fight. Here’s what you can do with it:

• Level up Blessings.
• Switch Blessings.
• Switch Equations.

There are also rarer Workbenchs that allow you to mess around with your Curio instead of Blessings.
