Honkai: Star Rail 4.6 Planar Fission mechanics
How the double reward triggers
Running Simulated Universe or Divergent Universe during the window grants double rewards: spending one event charge plus an Immersifier, or Trailblaze Power, pays an extra set of rewards on top of the normal drop . If honkai star rail character ranking gaps are what you are chasing, this window is the cheapest time to close them.
Participation rules and the charge cap
Access requires clearing Simulated Universe World Three . Double charges are capped and do not reset during the event, with remaining charges shown in the event screen . Charges simply expire when the window closes, with no compensation, so leaving runs unspent is a pure loss. Check the event screen before you log off for the night and spend anything left rather than assuming tomorrow will cover it.
Honkai: Star Rail Planar Ornament farming: which set first
Equilibrium level sets the drop count
At Equilibrium level 6, which is Trailblazer level 65, an Immersifier run can hand you 3 five-star Planar Ornaments at once . If you are short of that tier but close, level up first: the difference in output per charge is large.
Order for picking a set
Check your roster gap first, then the set ceiling. When resources are tight, farm the set that serves two or three characters at once . Past windows kept recommending the broadly useful sets for exactly that reason: a set that only fits one unit locks your charges into a single outcome, while a broad set gives you a usable result even if the sub-stats roll badly.
Honkai: Star Rail 4.6 meta: Pearl and the new Light Cone
Where Pearl fits
Version 4.6 launched on 2026-09-28 with Pearl as the new five-star, plus the limited five-star Light Cone Gift of Tomorrow's Colours; Phase 1 reruns Crimsonbrite and Phase 2 reruns Blade of a Thousand Forgings . honkai star rail team recommendations shift slightly around Pearl's role this patch.
Who to farm for first
My approach is to finish the Planar set Pearl's team needs, then consider spares . Do not stockpile spares first: most Planar sets only pay off as a full pair, so loose pieces are close to worthless.
Honkai: Star Rail Planar Fission efficiency tips
Save Immersifiers or spend them now
Bank Immersifiers and spend them in one push rather than trickling runs . The one-push approach lets you judge whether drops are landing as expected while there is still time to switch target sets. If your Immersifier stock is thin, split into two blocks instead, keeping the same target set inside each block so the sample is still readable.
Do not leave runs for the last day
Charges do not reset during the event but they do expire at the end . Server load also peaks on the final day, so finishing two or three days early is the safer play.
Honkai: Star Rail 4.6 resource plan: splitting Trailblaze Power
The Power budget during the window
At 12 runs and roughly 480 Trailblaze Power, the window eats about three to four days of natural regeneration . Push all Power into Planar Fission for that stretch; splitting it across other content lowers your return per point. Buy the Fuel the event screen offers if your stock runs dry mid-window, since the bonus is worth more than the usual rate.
What to do after the window
Once double drops end, Power goes back into Traces and Relics . Do not wait for a Relic double window that does not exist in this event: Relic caverns sit outside the bonus scope. Also, park overflow EXP for the next character you plan to build instead of dumping books into an already finished carry.Full archive at gghubs.com guides.
