Honkai: Star Rail - Optimal Team Compositions for Rappa

In Honkai: Star Rail, Erudition characters really shine when taking on multiple enemies at once, and Rappa perfectly fits this niche with her balanced mix of area-of-effect and single-target damage. However, she’ll need solid team support to truly excel, as she isn’t built to handle everything on her own.

Rappa’s kit has some unique nuances that call for careful team selection. Fortunately, with a wide range of characters in the HSR roster, you can create a team that not only addresses her weaknesses but also amplifies her strengths. Here’s the ideal team setup for Rappa, along with some alternative picks for players who may have limited rosters.

Best Team Setup for Rappa in HSR

Rappa’s Erudition path gives her an edge against enemy groups, especially with her focus on Break DMG. Due to this, traditional setups that depend on raw ATK or Crit boosts won’t be as effective for her. Instead, she benefits from Firefly team compositions within HSR. The best team setup for Rappa includes her alongside the following characters:

Synergy with Ruan Mei

Ruan Mei stands out as an exceptional support unit for any Break-oriented team, and her synergy with Rappa is especially strong. She accelerates the team’s ability to break Toughness Bars, which translates into more Charges for Rappa. In addition, Ruan Mei boosts the team’s damage with valuable ATK and All-Type RES PEN buffs.

Rappa’s Talent rewards her with a Charge each time an enemy experiences a Weakness Break (up to a max of 10 Charges). When she performs her third Enhanced Basic Attack during her Ultimate, one Charge is consumed, delivering up to 60% of her Break DMG across all enemies. This effect bypasses Weakness Types, allowing Rappa to break the Toughness Bars of foes resistant to Imaginary DMG.

Harmony Trailblazer and Lingsha

Harmony Trailblazer and Lingsha are excellent choices to further boost Rappa’s damage. Lingsha delivers heavy AoE Fire damage and, with her Ultimate, can amplify the Break DMG that enemies take. Meanwhile, Harmony Trailblazer enables the team to unleash Super Break DMG, significantly ramping up everyone’s damage output against Weakness-Broken enemies.

Together, these three supportive units enable Rappa to unleash considerable power with her Ultimate. If Rappa herself triggers the Weakness Break, she applies the Imaginary Imprisonment effect, delaying enemy actions and lowering their SPD.

Alternative Team Members

While most players should be able to build and use Harmony Trailblazer in Honkai: Star Rail, the availability of other characters may vary. For those who need substitutions, here are some 4-star alternatives:

- Gallagher: Serves as a replacement for Lingsha, offering healing, AoE Fire breaks, and Break DMG buffs. Built with a Break-oriented sub-DPS role in mind, Gallagher can maintain Rappa’s synergy even without Lingsha.

- Pela: Substitutes for Ruan Mei. Although she doesn’t enhance Weakness Break Efficiency, Pela can still help boost damage by reducing enemy DEF through her Ultimate.

- Asta: Another option for Ruan Mei’s slot, Asta provides useful ATK and SPD buffs, along with the ability to break multiple enemies at once.
