Honkai Star Rail Planar Fissure 300% guide: Best Simulated Universe worlds and Planar Ornaments to farm

Honkai Star Rail has brought back the Planar Fissure event with a special anniversary twist, offering triple the rewards in the Simulated Universe for a limited time. If you need new Planar Ornaments for your team, then there’s no better time to farm than now.

Honkai Star Rail 2.1 Planar Fissure 300% Schedule

The 300% Planar Fissure event will only be live for a week, beginning on Wednesday, April 10, 2024 and ending on Wednesday, April 17, 2024. That’s when the second half of Honkai Star Rail version 2.1 kicks off, bringing Aventurine’s banner and new events to the game. Be sure to take advantage of this Planar Fissure event to prepare for the road ahead.

Best Planar Ornaments to Farm in Planar Fissure

Since there are a ton of new characters that are incredibly powerful in Honkai Star Rail — like Black Swan, Sparkle, Acheron, and now Aventurine — you should take this opportunity to stock up on Planar Ornaments for them.

Of course, you should also take a look at your roster and see who could benefit from a new set of Planar Ornaments with better stats, but for the most part, this is a great time to farm gear for new units. Remember that you can only claim bonus rewards a total of 12 times throughout the Planar Fissure event period, so you’ll have to choose wisely.

Odds are that the newly-released Penacony characters on your roster will need new Planar Ornaments the most, so here are the best worlds and sets to farm for Honkai Star Rail characters released after version 2.0.

If you don’t have any Penacony characters and just want to farm a safe Planar Ornament set that works with basically everyone, then just blast through World 6 over and over again to stock up on Inert Salsotto pieces. This is an incredibly powerful pair of Planar Ornaments that boosts CRIT Rate and Ultimate damage (plus follow-up attack damage if you’re into that), making it a decent one-size-fits-all option. Plus, you can stock up on Belobog of the Ancients pieces for Aventurine while you’re there.

Technically, Aventurine‘s best set would be Broken Keel from World 7 since it buffs the team’s CRIT DMG as long as his Effect RES is high enough, but we chose the Belobog set for him on the table above since you’ll also get Inert Salsotto pieces from farming World 6. It’s a matter of efficiency. If you have Sparkle and are also saving for Aventurine, though, then definitely farm World 6 instead to get them both Broken Keel sets.

At the end of the day, however, the most efficient Simulated Universe world for you depends on which characters you’re trying to build. Try to pick Simulated Universe worlds where both Planar Ornament sets are useful instead of just one, that way you can maximize the efficiency of your farming and make the most out of your boosted drops. If you still can’t decide, then just choose Simulated Universe World 9 since it’s still relatively new and most people don’t have a stockpile of its Planar Ornament sets yet.
