Best Erudition Build for Rappa in Honkai: Star Rail

Unlike Feixiao’s Hunt build or Lingsha’s Abundance build, the Erudition build for Rappa in Honkai: Star Rail focuses on Imaginary Super Break, as she excels in area-of-effect (AoE) attacks. She shines in long battles with many enemies, like bosses that summon minions, such as Harmonious Choir or Starcrusher Swarm King. These situations allow Rappa to gain more skill stacks and boost her damage.

Unlike characters like Firefly or Boothill, Rappa needs more support from her team to maximize her Super Break, though her partner options are limited. Here is our guide for the best Erudition build for Rappa.

Erudition Build for Rappa

Rappa offers a fresh and fun playstyle with hand movements inspired by anime like Naruto, Jujutsu Kaisen, and Chainsaw Man. Her style also resembles the Spider-Verse aesthetic with Miles.

Best Light Cones for Rappa in Honkai: Star Rail

Rappa needs to enhance her Break Effect since Imaginary attacks are weaker than Fire or Physical. Speed (SPD) is also crucial for her stealthy attacks and getting more turns. Here are her best Light Cones:

Light Cone	Description
Ninjutsu Inscription: Dazzling Evilbreaker (5-Star)	Rappa’s Signature Light Cone is one of the best options for her build in Honkai Star Rail. It boosts her damage and energy at the start of the fight and provides an Action Advance for Basic Attack combos. It also enhances her Break Effect.
After the Charmony Fall (5-Star)	This is the second-best Erudition Light Cone for Rappa due to its Break Effect and Speed boost, which helps with Action Advance.
Before the Tutorial Mission Starts (4-Star)	This Light Cone improves Rappa’s Attack and Speed, essential for a DPS character like her to get more turns. It’s also more accessible since you can buy it at Herta’s Store.

Best Relics

To maximize Rappa’s potential, focus on these stats to make the most of her best set, Iron Cavalry Against the Scourge. These relics increase her Break Effect and let her ignore enemy defense. This build is especially powerful with the Ninjutsu Inscription Light Cone. Alternatively, Thief of Shooting Meteor is a great choice if you want to start with almost full energy, enhancing her Sealform’s combo attack.

Relic Piece	Description
Body Piece	Attack – Rappa can break enemies without Imaginary weakness but only deals 50% Toughness damage. Aim for about 3,200 Attack.
Feet Piece	Speed – After meeting other stat requirements, boost Rappa’s Speed to perform the Break Effect faster and possibly gain extra turns.
Planar Sphere	Attack – Focus on reaching 3,200 Attack and improving your Break Effect.
Link Rope	Break Effect – This is crucial for Rappa’s kit; aim for about 250% to make her attacks more effective.

For Planar Ornaments, use Talia: Kingdom of Banditry if you have enough Speed to benefit from its Break Effect buff. Alternatively, Forge of the Kalpagni Lantern can greatly enhance the Break Effect, but it’s more effective against Fire-weak enemies, so its use is limited.

Team Composition

Rappa can use the same teammates as other Honkai: Star Rail teams focused on Super Break, like those of Firefly. You don’t need to create a new team just for her, allowing you to focus on improving her stats. Here’s a suggested team:

Role	Characters
DPS	Rappa
Support	Ruan Mei
Support	Trailblazer (Imaginary)
Support	Lingsha or Gallagher

While her kit and build are familiar to players who have seen Super Break compositions in Honkai: Star Rail, Rappa brings a colorful challenge to the game.
