Honkai: Star Rail Simulated Universe Curios: A 2026 Guide from a Curio Hoarder

Hello, fellow Trailblazer. It is 2026, and I still hear the Simulated Universe whispering my name like a casino dealer who knows I have no self-control. I go in for weekly Stellar Jades, Trailblaze EXP, Credits, and Star Rail Passes, and I come out with 45 Curios, a headache, and a new personality. The Simulated Universe has six worlds, each one spicier than the last, and Curios are the little buffs—or curses—that make or break a run. Some are pure joy. Some are a Faustian bargain wrapped in a fortune cookie. And some make me stare at my screen like a raccoon who just learned taxes.

How Do I Get Curios? (And How Do They Get Me?)

Curios show up while you explore Simulated Universe worlds. At the start of a run, you can often choose a Curio or Blessings. You can also earn them after certain fights. My favorite source is Occurrence Rooms, marked by a blue portal and a question mark icon. Inside, you pick dialogue paths, and rewards can include Curios, Cosmic Fragments, Blessings, or a slap in the face from RNG. Sometimes Curios appear in the Transaction Room, marked by a blue portal and balanced scales. The catch? You must give up something you already have, usually a like-for-like Curio trade. It feels like a yard sale run by a trickster god who only accepts vibes as currency.

There are 45 Curios total. The first time you draw each one, you get 30 Stellar Jade. That is the real endgame: not beating the boss, but collecting shiny garbage until your inventory looks like a dragon's hoard. They broadly fall into five categories: Blessings, Cosmic Fragments, Character Boosts, Negative/Trade/Chance effects, and Other. All Curios last for the duration of your run unless stated otherwise. Let us break them down.

Curios That Affect Blessings

These Curios mess with the Blessings you get after battle. They can level them up, increase your choices, or hand you extra Blessings like a grandmother who thinks you are too skinny.

Curios That Affect Cosmic Fragments

Curios That Offer Character Boosts

These are the Curios that make your team feel like they drank eleven espressos and read a motivational poster. More HP, more damage, less damage taken, and sometimes weird speed.

Curios With Negative, Trade, or Chance Effects

Ah, my beloved cursed collection. These Curios either hurt you, gamble with your run, or give you a boost after a temporary kick in the shins. They are like a gym membership: painful at first, occasionally worth it, and sometimes you just cry in the parking lot.

My 2026 Curio Philosophy

After years of Simulated Universe runs, I have learned that Curios are not just buffs. They are tiny personality tests. Do you take the safe Blessing Curio, or do you gamble on Galactic Big Lotto and end up at 1% HP like a raccoon who tried to fight a vending machine? Do you hoard Cosmic Fragments with Society Ticket, or do you suffer through Angel-type I.O.U. Dispenser and pray the doubling is worth it?

My rule in 2026: if a Curio has 'Cuckoo Clock' in the name, I squint at it like it owes me money. If it has 'Sealing Wax,' I probably want it. If it has 'Code,' I prepare for three battles of emotional damage followed by a decent payoff. And if it is Fruit of the Alien Tree, I treat it like a precious emergency pizza: I hope I never need it, but I am glad it exists.

So go forth, Trailblazer. Collect all 45 Curios. Earn your 30 Stellar Jade each. Trade in the Transaction Room when you are feeling brave. And remember: the Simulated Universe is not a test of strength. It is a test of how much chaos you can smile through while pretending you meant to do that.
