I've been grinding the Simulated Universe in Honkai: Star Rail since day one, and let me tell you — Curios are the ultimate game-changer. As of 2026, with all the new worlds and Divergent Universe updates, these little trinkets still make or break your run. You can have the most cracked Blessings in the cosmos, but without the right Curios, you're toast. So here's my no-nonsense ranking of the eight best Curios you should always keep an eye out for. Trust me, these bad boys will save your bacon more times than you can count.
8. Dimension Reduction Dice 🎲
This one's a low-risk, high-reward situation. After winning a battle, you get to choose an extra Blessing — but it also removes one Blessing from the pool. Sounds like a trade-off, right? In practice, having more Blessings is almost always better. The only pain is when you see multiple great options and can only pick one. The Dice helps you snag more overall, and it's destroyed after two uses. Still, I'll take it every time.
7. Chaos Trametes 🍄
Ever hesitated to reset your Blessing choices because it costs Cosmic Fragments? Same here. Chaos Trametes gives you one free reset after each battle. It sounds unimpressive, but when your luck goes south and you're staring at a garbage pool of one-star Blessings, that free reroll is a lifesaver. Pair it with Fortune Glue and you're cooking with gas.
6. Fortune Glue 🍀
Rarity matters, folks. Fortune Glue guarantees that every Blessing that appears is three-star rarity. The catch? It's destroyed after one activation. So use it wisely — ideally right before a big boss fight or when you're desperate for a power spike. Combine it with Chaos Trametes for a free three-star refresh, and you've got insane value. This Curio is a straight-up blessing from the Aeons.
5. Record From Beyond The Sky 📀
This Curio can really save your bacon against annoying bosses who attack first and spam debuffs. When battle starts, all damage your characters take is nullified until after they're attacked, and they're immune to debuffs for three turns. Damage Over Time still ticks, so watch out for that. But against those cheap first-strike enemies, this thing turns the tables. And it doesn't expire after a set number of triggers — absolute chef's kiss.
4. The Doctor's Robe 🥼
Path Resonance is a mechanic that can bail you out in a pinch, so more Energy is always welcome. The Doctor's Robe maxes out your Path Resonance Energy at the start of every battle and boosts Path Resonance DMG by a whopping 40 percent. Best part? It never expires. Get ready to spam that Path Resonance like there's no tomorrow. This is one of the most overpowered Curios in the game, hands down.
3. Infinitely Recursive Code 💻
Code Curios are a double-edged sword — they debuff you for three battles before flipping to a positive effect. Infinitely Recursive Code is the poster child. While active, every Skill costs one extra Skill Point, so you need to plan carefully. But after three battles, every Basic ATK recovers one extra Skill Point. That means you can spam Skills like a madman. Survive the early penalty and you're golden. It's a high-risk, high-reward play that pays off big time.
2. Punklorde Mentality 🎸
Exploiting enemy weaknesses is turn-based combat 101. This Curio makes it so that, for three turns, all enemies are guaranteed to have a weakness matching one of your characters' elements. Even if your team is mono-element, that 100 percent weakness chance makes shredding through tough enemies a breeze. It's a staple for any run where you want to ensure victory. No cap, this Curio is the real deal.
1. The Parchment That Always Eats 📜
Looks menacing, right? But it's only a menace to your enemies. Every time you enter battle, all enemies take damage equal to 30 percent of their Max HP. That's massive. It speeds up fights, prevents annoying deaths from nearly-dead enemies, and helps you deal with tanky foes whose weaknesses you can't cover. The secret to success is damaging the opponent before they damage you — and this Curio does exactly that. It's my number one pick, no contest.
Quick Summary Table
| Rank | Curio | Effect | Why It's Great |

| 8 | Dimension Reduction Dice | Extra Blessing choice, minus one option | More Blessings overall |

| 6 | Fortune Glue | All Blessings are three-star rarity | Guaranteed high rarity |
| 5 | Record From Beyond The Sky | Nullify first damage, immune to debuffs for 3 turns | Counters first-strike bosses |
| 4 | The Doctor's Robe | Max Path Resonance Energy, +40% DMG | Spam Path Resonance |
| 3 | Infinitely Recursive Code | Extra Skill Point cost for 3 battles, then extra recovery | Late-game Skill spam |

So there you have it — my go-to Curios for dominating the Simulated Universe in 2026. Keep these in mind, and you'll be clearing runs like a pro. Happy trailblazing! 🚀
