Longest Double Drop Event of the Year! Honkai Star Rail's Planar Fissure Runs 14 Full Days
HoYoverse has officially confirmed that Planar Fissure is returning to Honkai Star Rail Version 4.4, handing out double rewards for Planar Ornaments through the Simulated Universe. What makes this particular Honkai Star Rail event worth highlighting is simple: it runs noticeably longer than past reruns.
According to the official HoYoLAB announcement, this Honkai Star Rail event runs from July 27, 2026, at 04:00, through August 10, 2026, at 03:59 (server time) a full 14 days. That's roughly double the length of most previous Planar Fissure reruns in Honkai Star Rail, which have typically lasted about a week. For players who usually run out of time to farm before an event closes, this extra window in Honkai Star Rail is genuinely good news.
Requirements to Join
Per HoYoverse's official post, the requirement to participate in this Honkai Star Rail event is straightforward: you need to have already unlocked Planar Ornaments in other words, reached Simulated Universe World 3 and cleared the related story prerequisites before you can take advantage of the double rewards.

How the Planar Fissure Event Works
Based on the official details HoYoverse provided, here's exactly how this Honkai Star Rail event functions:
During the event period, you'll receive double rewards every time you claim Immersion Rewards or perform Ornament Extraction in the Simulated Universe.
These bonus rewards come on top of the default drops, after you use up an event double reward opportunity plus an Immersifier (or Trailblaze Power).
The number of double reward opportunities during the event is limited, and the exact count can be checked directly on the Planar Fissure event page in-game.
The double reward count does not reset during the event, so plan your Honkai Star Rail farming schedule accordingly.
Worth noting: in past Planar Fissure reruns going all the way back to Honkai Star Rail's Version 1.1, the number of available double reward opportunities has consistently sat at 12 claims for the whole event window. That said, since HoYoverse's official post for this Version 4.4 run doesn't explicitly state the exact number this time around, the most accurate way to confirm your own count is to check the in game event page directly rather than assume it's identical to previous runs.

Farming Tips So Nothing Goes to Waste
Since your double reward opportunities are limited and won't refresh, it pays to plan ahead in Honkai Star Rail:
Decide which Ornament set to prioritize before you start farming. Check what your main Honkai Star Rail characters actually need a DPS carry, a sub DPS, or a support unit so your limited double reward claims don't end up going toward a set you won't actually use.
Use up any Immersifiers you're sitting on first, so you don't burn through the regular Trailblaze Power you'll also need for other daily Honkai Star Rail activities.
Don't rush to spend every opportunity on day one. With a full 14 day window this time, you have more breathing room to bank Trailblaze Power through your daily resets first, then farm in a concentrated push closer to the event's final days if that fits your schedule better.
Check Ornament Extraction in the Divergent Universe as an alternative if you already have a save file there it's a faster way to farm since you can jump straight into a combat challenge without progressing through a Domain the way you would in the standard Simulated Universe.
Set aside some Trailblaze Power for your regular daily routine too, like Daily Training and Calyx runs, so grinding this event doesn't end up eating into your other everyday Honkai Star Rail progress.
How This Run Compares to Past Planar Fissure Events
To put the length of this Honkai Star Rail double drop window in perspective, here's how a few previous Planar Fissure runs stacked up:
The most recent rerun before this one, in August-September 2025, ran from August 27 to September 8, about 12 days total.
The rerun back in January 2025 ran exactly one week, from January 27 to February 3.
Going further back, the September 2024 rerun also ran exactly one week, from September 23 to 30.
Compared to those, the 14 day window in Version 4.4 is genuinely one of the longest Planar Fissure events Honkai Star Rail has run to date even longer than the 12 day version from last year. It likely lines up with Version 4.4's Phase 2 banner lineup, which brings back several rerun characters at once (Cerydra, Anaxa, and Aventurine), giving Honkai Star Rail players more flexible time to farm the ornament sets those characters need.
A Quick Note on Immersion Rewards vs Ornament Extraction
The two ways to earn boosted Planar Ornaments during this event work a little differently:
Immersion Rewards (Simulated Universe): you need to defeat an Elite Boss in your chosen world to unlock the Immersion Device before you can claim an Ornament from it. Which set drops depends on the world and domain you're running.
Ornament Extraction (Divergent Universe): if you already have a Divergent Universe save file, you can jump straight into a combat challenge without needing to progress through a Domain the way Simulated Universe requires, making it a quicker option for shorter farming sessions.
Both methods get the same double-reward boost for the full event duration, so you can pick whichever fits your account's current progress in Honkai Star Rail.
One more thing worth remembering: the cost to claim rewards stays exactly the same even though the drop rate is doubled. If a single Immersion Reward claim normally costs 40 Trailblaze Power or 1 Immersifier, that cost doesn't change during the event only the amount of Ornaments you get per claim does.
How to Join Step by Step
Make sure you've already unlocked Planar Ornaments (Simulated Universe World 3).
Open the Travel Log from the Pause Menu, and find the Planar Fissure tab to check your remaining double reward count.
Head into the Simulated Universe and clear the Elite Boss in your chosen world to unlock the Immersion Device.
Spend an Immersifier or Trailblaze Power to claim your reward as long as you're within the July 27 - August 10, 2026 window, you'll automatically get the doubled drop.
Repeat until your double reward opportunities run out, or until you've farmed enough of the Ornament set you're after.
