The most expensive mistake in this event is assumption, not luck. Honkai: Star Rail players routinely burn a full day of power on cavern relics expecting double drops, then wonder why the count looks normal. This guide separates the two relic families, prices the 240-power day, covers the new 4.6 cavern sets, and settles whether Pearl is worth a 90-pull guarantee.
| Item | Verdict | Basis |
|---|---|---|
| Planar Split | Planar Ornaments only | Official notice, 2026-10-11 11:00 |
| Immersifier cost | 40 Trailblaze Power | Six runs per 240-power day |
| New relics | Cavern sets excluded from the bonus | Official 4.6 patch notes |
| Pearl | Pull if you lack an Elation slot | Limited five-star, 90-pull cap |

Honkai: Star Rail 4.6 Planar Split: what actually doubles
The official notice states that Planar Ornaments drop at double rate during Planar Split, with the notice dated October 11 at 11:00 . Planar Ornaments come from the Simulated Universe, and that is the only place the bonus applies.
It is not a blanket relic bonus
This is not "double relics"; it is double Planar Ornaments, meaning the rope and sphere two-piece slot only . Cavern relics, the head, hands, body, and feet four-piece set, come from a different activity and get nothing.
Why the bonus is worth more than it looks
The Planar Ornament sub-stat pool is narrower than the cavern pool, so the odds of a usable roll are higher. If a character is missing one elemental damage sphere with crit on it, this window is the best odds you will get.
Honkai: Star Rail Planar Ornament choices
Planar Ornaments come as two-piece sets: the rope rolls attack or HP, the sphere rolls elemental damage or effect hit rate . Set effects usually key off a speed threshold or a crit condition, so confirm the character can trigger it before farming the set.
Do the speed math first
Many Planar sets only activate above a speed threshold, and below it the set does nothing. Add base speed, light cone, and sub-stats first, then decide whether the set is worth trading attack sub-stats for.
Do not force crit conditions
A set that needs a specific crit rate to trigger is a blank at low crit rate. That is not an argument against the set; it is an argument for fixing crit rate before evaluating set value.
Honkai: Star Rail 4.6 new relics: cavern versus planar roles
Patch 4.6 adds the cavern sets Dream-Spotting Performer and Heretic Who Devoured the Forbidden Fruit, farmed from the Corrosion Cave Melody Path . Both are four-piece sets, so they do not conflict with Planar Ornaments but do compete for the same power.
How the new sets split
New cavern sets usually match a new damage pattern or trigger condition . Read the trigger clause: wording like "after using Ultimate" or "when dealing damage over time" means the set is built for a specific rotation, not for everyone.
Which to farm first
Planar Ornaments first, because only they are doubled. Cavern relics can wait until the event ends, and this ordering doubles the planar output for the same power.
Honkai: Star Rail 4.6 power requirements
One Immersifier costs 40 Trailblaze Power and natural regeneration gives 240 a day, so six runs. Planar stages drop one ornament per run, doubled to twelve during the event, with usability still decided by sub-stats.
| Item | Amount | Conversion |
|---|---|---|
| Daily power | 240 | Six Immersifier runs |
| Planar output in event | 12 per day | About 6 usable at a 50 percent hit rate |
| Relic leveling | Multiple rounds each | Credits plus relic EXP |
| Pulls | 90 soft cap | 160 Stellar Jade per pull, 28,800 worst case |
A week that fits
Monday through Thursday on Planar Ornaments while the bonus is live, Friday and Saturday on cavern relics and trace materials, Sunday on Simulated Universe weeklies. The bonus has a window; trace materials do not.
Honkai: Star Rail 4.6: is Pearl worth pulling
Verdict first: pull Pearl if you lack an Elation slot or want a Cryo damage-over-time core; skip if your Elation team is already finished. She is not a mandatory mechanic character .
Three account types
New accounts under six five-stars: pull, since an Elation slot travels across modes. Mid-game accounts clearing Forgotten Hall: check the light cone banner, because Her Colour for Tomorrow moves damage more than an early eidolon. Veterans: pull only for preference, as 4.6 adds no mandatory mechanic.
Build before banner
Can you build her? Pearl wants new trace materials and relics, so if the Planar Split week produces nothing usable, the pull sits in storage. The same logic behind Honkai: Star Rail team comps applies here: roles are scarcer than numbers.
Honkai: Star Rail 4.6 Forgotten Hall speed tuning
Forgotten Hall grades on cycles, not on a single burst window . The goal is therefore one extra turn inside the cycle cap, not one bigger hit.
Why speed matters
Putting the carry just after the supports lets buffs land inside the same cycle . That is why speed boots show up more often than attack boots in Forgotten Hall clears: not because damage is higher, but because the team gets another turn.
Never cut the battery
The battery decides ultimate frequency. Without it, the carry's burst window slips from every two cycles to every three , which in a fixed cycle cap is the difference between one star and two.
Honkai: Star Rail FAQ
Does Planar Split double cavern relics too?
A: No. It only doubles Planar Ornaments, the rope and sphere two-piece slot; cavern relics come from a separate activity .
How much power does one Immersifier cost?
A: 40 Trailblaze Power, and 240 daily regeneration equals six runs, or about 12 Planar Ornaments during the event.
Where do the 4.6 relics drop?
A: Corrosion Cave Melody Path, which drops Dream-Spotting Performer and Heretic Who Devoured the Forbidden Fruit .
Does Pearl need her signature light cone?
A: Not strictly, but Her Colour for Tomorrow moves damage more directly than an early eidolon .
Why speed boots in Forgotten Hall?
A: So the carry acts after the supports and buffs land in the same cycle; an extra turn beats a bigger single hit .

Version 1.0.5 only fixes textures, but the breeding line changed for good when 1.0 added Mutation, a low-probability upgrade during breeding. Getting reliable four-passive Pals is still an engineering problem: start from clean parents, merge narrow passive pools, and treat Mutation as a bonus instead of a plan.
- Reverse: 1999 4.0.0 Yingmenzhe: 40 Sign-In Pulls, Insight III Order, Real Costs
Version 4.0.0 landed on September 24, and the hardest number in its reward list is 40 limited sign-in pulls, followed by a guaranteed-new six-star and a selectable six-star Reverie character. Claim the sign-in before you spend anything, then decide who gets Insight III, because doing it backwards trades future pulls for current power.

The Snowball event that opened on October 19 at 12:00 is the only new gameplay in the back half of Genshin Impact 7.1, and it sits next to two Cryo banners that have been live since October 8 at 16:00. Do the event first, count the primogems second, and pull third, because a 90-pull guarantee costs 14,400 primogems before you even discuss who is stronger.
- Wuthering Waves 3.7 Tower of Adversity: Three Teams, Echo Stats, Real Costs
Tower of Adversity in Wuthering Waves 3.7 still forces three teams that share no characters, and that single rule decides how you spend everything else. Fix your three carries first, then build echoes on a 4-3-3-1-1 cost split: 60 percent crit rate and 120 percent crit damage on the carry, energy regen only on supports.
- Zenless Zone Zero 3.2 Double-Drop Window: Drive Discs, W-Engines, Battery
Battery, not pulls, is the real bottleneck in Zenless Zone Zero 3.2. With the Data Bounty training-room double reward live since October 12, the correct order is character ascension materials first, drive disc main stats second, sub-stats never chased past 60 percent crit rate and 120 percent crit damage.

Since v1.0.4 dropped Ancient Bark gathering to Work Suitability Lv. 1, the early wood chain costs far less to start .
