Her Skill, Ninja Strike: Rooted Resolute, deals Imaginary Damage based on her Attack to all foes on the field.

Rappa’s Ultimate, Nindō Supreme: Aishiteru, allows her to enter the Sealform state, gain another turn immediately, obtain three Chroma Ink points, and increase her Weakness Break Efficiency as well as her Break Effect. The Sealform state unlocks her Enhanced Basic Attack, consuming one point of Chroma Ink. When Chroma Ink is depleted, the Sealform state ends.

Her Enhanced Basic Attack, Ningu: Demonbane Petalblade, deals Imaginary Damage based on Rappa’s Attack to one target and adjacent units with the first two hits and then to all foes with the third hit. This move does not recover Skill Points, but reduces the Toughness of enemies even if they do not have the Imaginary Weakness Type.

When Rappa inflicts Weakness Break on enemies, she unleashes a bouncing attack that deals Break Damage to its targets and reduces their Toughness regardless of Weakness Type. While the bounces are random, they will prioritize targets that have not been Weakness Broken yet.

Rappa’s Eidolons, which are obtained by pulling more copies of her, provide further upgrades. Eidolon 1 allows Rappa to partly ignore enemy Defense in her Sealform state and regenerates some Energy for her when she leaves the state. Eidolon 2 increases the Toughness Reduction of the first two hits of her Enhanced Basic Attack. Eidolon 4 boosts the entire team’s Speed when Rappa is in the Sealform state. Eidolon 6 increases her Talent’s Break Damage multiplier on the triggering target as well as the number of bounces.

Honkai: Star Rail – Rappa: best Light Cones

Rappa’s best Light Cone is her signature gear, Ninjutsu Inscription: Dazzling Evilbreaker. It buffs the wearer’s Break Effect and immediately generates Energy for them at the start of battle – this speeds up Rappa’s way towards her Ultimate and the Sealform state. After using an Ultimate, the wearer gains the Raiton status effect, which advances their action forward after using two Basic Attacks (or Enhanced Basic Attacks).

Best Light Cones for Rappa in Honkai: Star Rail:

• Ninjutsu Inscription: Dazzling Evilbreaker (5-Star)
• Night on the Milky Way (5-Star)
• Eternal Calculus (5-Star)
• After the Charmony Fall (4-Star)
• The Day The Cosmos Fell (4-Star)
• The Seriousness of Breakfast (4-Star)
• Geniuses’ Repose (4-Star)

Honkai: Star Rail – Rappa: best Relics

Rappa mainly wants three stats: Break Effect to enhance her Break Damage, Attack to boost her Enhanced Basic Attack’s damage, and Speed to quickly attack and charge her Ultimate – you’ll want to hit the magic number of 160 Speed for the best possible performance. Her Attack also helps boost Break Damage taken by enemies thanks to one of her Traces. 

Rappa should produce enough Energy through another one of her Traces, which provides some when Elites on the field get Weakness Broken, as well as the built-in regeneration at the end of the Sealform state. However, if you find yourself unable to keep Sealform up consistently, it may be worth investing into Energy Regeneration.

You don’t require Critical stats on Rappa, since her Break Damage can’t trigger critical hits, so the remaining stats can be divided up into things like Defense and Effect Resistance that help keep Rappa alive and free from debuffs.

Rappa is another fine addition to the Break Meta, though with more of a focus on clearing waves.

• Rappa (Main DPS), Trailblazer (Harmony) (Support), Ruan Mei (Support), Lingsha (Sustain)

You basically take the ideal Firefly team and swap her out for Rappa. Trailblazer (Harmony), Ruan Mei, and Lingsha all come with kits that boost a Break-focused playstyle, accelerating Weakness Break speed and damage. Don’t worry if you don’t have Lingsha, because there’s quite a powerful alternative in Gallagher.
