Stuck on the Kafka boss fight? Our Honkai Star Rail Simulated Universe World 5 guide should help you out.

Simulated Universe is one of the many in-game activities in Honkai: Star Rail, and the difficulty can scale rather quickly. World 5 is the first time you’ll experience a challenging debuff mechanic. The World 5 boss, Kafka, can be a tough battle if you don’t have the right team composition and Resonance. Luckily, our Honkai Star Rail Simulated Universe World 5 will help you breeze through this fight and nullify Kafka’s attacks.

Honkai Star Rail: Simulated Universe World 5 Guide

To defeat Simulated Universe World 5 in Honkai Star Rail, you’ll want a team of characters that can debuff, heal, and deal high Wind, Physical, or Illusionary damage. You will also want to build into the Abundance Resonance Path for extra healing and debuff resistance. At 6 Blessings of Abundance, you can pick up Anicca, and then at 12 Blessings of Abundance, you can pick up Nirvana. With these Blessings, the fight is very easy.

Here are some key things you’ll want to have for the World 5 boss fight:

  • Team Composition: Natasha, March 7th, Dan Heng
  • Blessings: Abundance, Anicca, Nirvana
  • Curios: Bonus Speed, Damage, and Defense

Team Composition

The best team composition for Simulated Universe World 5 is:

  • DPS: Dan Heng or Sushang
  • Heal: Natasha
  • Support: March 7th, Bronya
  • Alternative Supports: Trailblazer (Fire), Gepard, Tingyun

Kafka is weak to Wind, Physical, and Illusionary and highly resistant to Electric. For that reason, it’s a good idea to have your main DPS be someone like Dan Heng if you’re free-to-play or Sushang if you have her built up.

Honkai Star Rail: Simulated Universe World 5 - Kafka

The Kafka boss fight is extremely healing and debuffing dependant. Kafka deals heavy damage and often debuffs a member of your team with a move called Domination, effectively charming them and making them hostile. Luckily, you can cleanse Domination using Natasha or March 7th. You must unlock Natasha’s Soothe Trace or March 7th’s Purify Trace to remove debuffs from allies. Additionally, you can cleanse this with the Abundance Resonance Formation: Anicca, which we’ll go over in the next section.

As for your character builds, ensure your main DPS has a lot of Speed, CRIT Rate, CRIT Dmg, and ATK. Cruising in the Stellar Sea is a good Light Cone to run on The Hunt characters. For Natasha, make her very tanky and use the Healing Set. Lastly, for your defensive character, like March 7th, Gerpard, or Trailblazer (Fire), stack defensive items on them.

Blessings

The best Blessings to get for Simulated Universe World 5 is:

  • Path Resonance: Abundance
  • Resonance Formation: Anicca, Nirvana

The easiest Path Resonance to use for World 5 is Abundance. The Abundance Path makes it so you can spend 100 points of Energy to restore HP for all allies by 50% of their respective Max HP and increase their respective Max HP by 15% for two turns.

However, the useful part is not the heal — it’s the Resonance Formation: Anicca, which makes it so this move cleanses all ally debuffs and applies a stack of Subduing Evils for one turn. Subduing Evils (5 stacks max) can be consumed to resist one debuff and heal the character. Upgrade this Blessing to get two stacks of Subduing Evils, making the Kafka fight much more straightforward.

Honkai Star Rail: Resonance Formation Anicca

When you have Resonance Formation: Anicca, save it for when Kafka applies the debuff to one of your characters. Then, cast the skill to cleanse it and get debuff protection. If Kafka gets another debuff on you, you can use Natasha, March 7th, or Bronya to cleanse it.

Another viable option is the Remembrance path. In this path, you can stack Freeze and damage to frozen enemies, which will keep Kafka frozen and apply Dissociation, increasing her damage taken for some time.

Curios

The best Curios for Simulated Universe World 5 are:

  • Shattered Star Bait: Advance Forward after taking action.
  • Normal Code: Reduces damage taken by allies.
  • Robe of the Beauty: Increases damage for every 100 Cosmic Fragments owned.
  • Space-Time Prism: Increases ally’s Eidolon Resonance by 1.

Curios providing bonus speed, reduction, and increased damage output are great for the Kafka battle. It’s a long fight, so Curios like Shattered Star Bait, Normal Code, and Robe of the Beauty are good options.

Using these Characters, Bessings, and Curios, you can easily trivialize the Simulated Universe World 5 boss fight against Kafka. Hopefully, this Honkai Star Rail Simulated Universe World 5 guide helps you clear this area if you are having trouble.
