Honestly, looking at the Pure Fiction or Memory of Chaos rewards is one thing, but staring down a HSR Anomaly Arbitration 0 cycle F2P run feels like a completely different beast. You’re basically trying to outrun a timer that doesn't want you to win. Most players see "Anomaly Arbitration" in the Divergent Universe or the latest endgame rotations and assume you need a C6 (E6) Acheron or a wallet deep enough to buy a small car.
They're wrong.
Getting a 0-cycle clear as a Free-to-Play player in Honkai: Star Rail isn't about brute force. It is about exploitation. You have to exploit the action gauge, the specific buffs provided by the Anomaly, and the elemental weaknesses of the bosses like your life depends on it.
What the Anomaly Arbitration 0 Cycle F2P Run Actually Requires
Let’s get real for a second. If you’re F2P, you aren’t winning with "decent" builds. You need specialized ones. Anomaly Arbitration often introduces specific mechanics—like the "Equations" in Divergent Universe or specific turbulence buffs in MoC—that favor certain paths.

To hit that elusive zero, you need to understand the Action Value (AV) system. A 0-cycle means finishing the fight before the first 100 AV passes in the first wave, and before the subsequent 100 AV passes in the next.
Speed is king. But not just "I have 134 speed" king. I'm talking "I have 160+ speed on my supports and Dance! Dance! Dance! at Superimposition 5" king.
Why Energy Regeneration is Your Best Friend
You can't wait for your turn. In a 0-cycle run, waiting is losing. This is why characters like Tingyun or Huohuo (if you were lucky enough to snag her) are essential for F2P players. Tingyun with a Vonwacq set allows her to move first, dump energy into your DPS, and get the ultimate rotation moving before the boss even blinks.
If you're running a Break Effect team—which is currently the F2P gold standard thanks to the Harmony Trailblazer—your energy needs shift slightly. You aren't just looking for raw damage; you're looking for the moment the toughness bar snaps.
The "Super Break" Loophole
If you want an HSR Anomaly Arbitration 0 cycle F2P result today, you are likely using the Harmony Trailblazer (HTB). It is the most "broken" thing Hoyoverse has given F2P players since the game launched.
Pair HTB with Gallagher.
Yes, a four-star healer.
Gallagher is a monster in Anomaly Arbitration because his ultimate provides an immediate 100% Action Forward. If you time his ult right, he can basic attack, ult, and then basic attack again instantly. That is a massive amount of toughness damage in a single window. When combined with Ruan Mei (if you saved your pulls for her) or even an Asta, the speed scaling becomes astronomical.
Asta is often overlooked. Don't do that. Her ultimate provides a flat speed boost that can push your entire team over the threshold needed to act three times in the first cycle. That's how 0-cycles happen. You don't just hit harder; you hit more often.
Managing the RNG
Let's be honest: 0-cycling as F2P is a bit of a reset simulator.
You need the enemy to hit the right person to give them that tiny bit of extra energy. You need the crit to land if you’re playing a traditional DPS like Dr. Ratio. If you're playing the Anomaly Arbitration modes where blessings or "weighted curio" effects are active, you need to hunt for the ones that specifically trigger "Brain in a Vat" or "Hunt" path resonances that refresh turns.
The Specific Teams That Actually Work
Forget the Tier Lists for a minute. When you're restricted by F2P light cones and eidolons, certain units shine way brighter in 0-cycle scenarios.
The Break Core:
- Harmony Trailblazer: Essential. Period.
- Gallagher: Best F2P sustain for break damage and AV manipulation.
- Sushang or Dan Heng (Wind): Both have ways to advance their own actions. Sushang’s ultimate resets her turn. Dan Heng gains wind penetration and speed boosts.
- Pela: Her defense shred is universal and she’s incredibly SP positive.
The "Ratio" Hypercarry:
If you got Dr. Ratio for free (the golden era of HSR), he is still a 0-cycle king. Pair him with Pela on "Resolution Shines as Pearls of Sweat" and a fast Tingyun. The goal here is to trigger his follow-up attacks constantly. In Anomaly Arbitration, if there's a buff that triggers on "Follow-up Attacks," Ratio can clear waves before the cycle counter even moves.
Gear Check: No, You Can't Ignore Substats
You’ve probably heard people say "Main stats are enough." Not for this.
For a 0-cycle, your supports need to be fast. Ridiculously fast. You should be aiming for the 160.1 speed breakpoint on Pela and Tingyun. This allows them to move twice in the first cycle and three times if you have any source of Action Advance.

For your DPS, stop over-investing in ATK%. Use an elemental damage orb. Use a Speed boot unless you are running a dedicated "Bronya/Sparkle" setup where they pull the DPS forward.
Breaking Down the Anomaly Mechanics
Anomaly Arbitration usually involves specific "Anomalies" that change every few weeks. Sometimes it’s a "Memory Turbulence" that deals massive damage when you use a certain number of Skill Points. Other times, it’s about inflicting status ailments.
If the current Anomaly favors Damage over Time (DoT), and you don't have Kafka or Black Swan, don't panic. Guinaifen and Sampo are viable. The trick is to use the Anomaly to do the heavy lifting for you. If the Anomaly deals 25% of the boss's HP when they are "Wind Sheared," your goal isn't to build a 3000 ATK Sampo. Your goal is to build a 160 Speed Sampo who applies Wind Shear as fast as humanly possible to let the stage mechanic kill the boss.
That’s the secret. The game wants to help you. The Anomaly is a tool, not just a background effect.
Common Mistakes in F2P 0-Cycle Attempts
- Holding Ultimates: You see people "saving" ultimates for the boss. In a 0-cycle, that's a death sentence. You use Tingyun's ult the second she has it to get the DPS moving. You use Pela's ult to clear the small adds immediately so the big boss takes the "bounce" hits from your skills.
- Ignoring the Break Bar: In many Anomaly modes, enemies take significantly more damage—or even take a massive HP hit—the moment they break. Timing your breaks so they happen at the start of your DPS's turn maximizes the "vulnerability" window.
- Bad SP Management: Running out of Skill Points on turn 2 is the #1 reason F2P runs fail. You have to balance. Maybe Gallagher doesn't use his skill. Maybe Pela only basics.
The Importance of the "Secret" 3-Star Light Cones
Don't sleep on "Multiplication" (Abundance) or "Meshing Cogs" (Harmony).
"Multiplication" on Gallagher makes him move 20% faster every time he basics. This is how you get enough SP to keep your DPS spamming skills. "Meshing Cogs" on Tingyun or HTB is often better than most 4-star cones because it guarantees a 3-turn ultimate rotation. Without that energy, you won't hit the 0-cycle.
How to Pilot the Final Fight
When you reach the final boss of the Anomaly Arbitration, the AI is your enemy. You must manual this.
Targeting matters. You need to chip away at the toughness bars of the side mobs so that a single AoE hit from your Trailblazer or DPS breaks all of them simultaneously. This triggers the Anomaly's chain reaction.
If the boss has a phase change (like Sunday or the Aventurine boss), you need to time your "big" hits to carry over. Excess damage doesn't always spill over perfectly, so don't waste a 100k ultimate on a boss with 2k HP left in Phase 1. Use a basic attack to finish them, then unleash the ultimate the second Phase 2 starts to maximize the cycle efficiency.
Actionable Steps for Your Next Run
To actually pull this off, stop grinding generic relics and start focusing on these specific adjustments:
- Check your Speed Breakpoints: Get your supports to 160.1 speed using 2-piece Messenger Traversing Hackerspace and any random pieces with high speed substats. Set bonuses (other than speed) don't matter as much as the raw stat.
- Max out your "Meshing Cogs" and "Multiplication" cones: They are 3-star items. You likely have dozens. Max them out and put them on your Harmony and Abundance characters.
- Level your traces to 9 or 10 for key abilities: For HTB, that means the Ultimate. For Pela, that means the Talent and Ultimate. For your DPS, it’s everything.
- Abuse the "Reset" button: If the first wave doesn't end with your team having at least 50% energy and 0 cycles spent, reset. It takes practice to get the flow right.
- Study the Anomaly: Read the text. If the current buff gives you energy when an enemy is defeated, make sure your DPS is the one getting the killing blow.
Success in HSR Anomaly Arbitration 0 cycle F2P isn't about having the best luck with pulls. It’s about having the best understanding of the clock. Every action has a cost in AV. Your job is to make those actions free. When you finally see that "0" on the screen after the boss disintegrates, you'll realize the game isn't pay-to-win—it's think-to-win.
