Divergent Universe (DU) is another version of Simulated Universe inHonkai: Star Rail. The game mode is meant to ease theprocess 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 andGold 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 theDivergent Universe inHonkai: Star Rail.

How To Unlock Divergent Universe
To unlock the Divergent Universe inHonkai: Star Rail, players simply need to clearSimulated Universe: World 3in Herta’s Space Station. It’s highly recommended to completeStranger in a Strange Land Trailblaze Missionin Penacony so that Trailblazers won’t lose the immersion, but it’s not a necessity.
If players skip the main quest, they’ll gainaccess to the areas of Radiant Feldsparthat 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 theCharacter Mappingsystem. This mechanic does the following:
This allows players to use any character they have without worrying about raising them first. However, this also means players need to be careful assome 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 canfreely change their team in the Divergent Universe runwithout having to use the “Download” machine. Divergent Universe alsodoesn’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 ExtrapolationandCyclical Extrapolation.
Ordinary Extrapolationis the “basic” version where players can unlock new difficulties to test their limits. Meanwhile,Cyclical Extrapolationis 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 theEquationmechanic. Unlike in theSimulated Universe where you follow one Pathand you must collect Blessings for that specific Paths, the DU is heavier on RNG with its Equation system. Basically, here’s how it works:
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 obtain16of the respective Path’s Blessing.

New Items
Other than the aforementioned information, Divergent Universe inHonkai: Star Railalsocomes with revamped Occurrenceand Blessings, more diverse Domain options, new Interactables, Curio, and Weighted Curio.
One of the most important changes is the existence of theWorkbench of Creation. Unlike in Simulated Universe where you may 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’re able to do with it:
There are also rarer Workbenchs that allow you tomess around with your Curioinstead of Blessings.
