Best Light Cone
Back to All Characters
Rappa is an AoE-oriented DPS character inHonkai: Star Railwho specializes in Break DMG,much like Boothill or Firefly. Given her focus on this niche playstyle, she benefits most fromstats such as Break Effect, ATK, and Speed. However, as the first Erudition character to center her kit around Break DMG, Rappa’s ideal light cone options are somewhat limited, especially since she cannot effectively use common DPS stats like Crit Rate or Crit DMG.
Fortunately, despite the narrower range of choices, there are still several great light cones available to maximize Rappa’s potential. Whether players opt for premium 5-star light cones, 4-star gacha options, or more accessible F2P alternatives, these options can help her thrive in Break DMG-focused teams. Here are the best light cones for Rappa inHonkai: Star Rail.

S5 Passive
Increases the wearer’s ATK by32%. When the wearer defeats an enemy, the wearer’s CRIT DMG increases by48%for 3 turn(s).
WhileGeniuses' Reposeisn’t fully synergistic with Rappa, it can still serve as a solid option for players who have it at max superimposition and lack better alternatives from her list of light cones. This is because, despite the conditional Crit DMG buff—which isn’t particularly useful for Rappa due to her focus on Break DMG—the 32% ATK increase it offers immediately is valuable. Unlike other light cones likeThe Seriousness of Breakfast, which require stacking conditions to build up ATK,Geniuses' Reposeprovides its ATK bonus instantly, making it more reliable in that regard.
Similarly,The Day The Cosmos Felloperates in a comparable way, offering a passive ATK buff. However, its ATK increase is notably lower than whatGeniuses' Reposeprovides when fully superimposed, making it a less effective choice for maximizing Rappa’s Break DMG potential, as her Break DMG scales with ATK as well.

S1 Passive
For every enemy on the field, increases the wearer’s ATK by9.0%, up to 5 stacks. When an enemy is inflicted with Weakness Break, the DMG dealt by the wearer increases by30%for 1 turn.
Night on the Milky Waycan be seen as a “Freemium” option for Rappa, since it’s not a limited 5-star light cone and can even be obtained through the in-game shop. While it’s not recommended to prioritize purchasing this light cone solely for Rappa, players who already own it should definitely consider it, especially in content where multiple enemies are present on the field. When fighting against five enemies, Rappa can gain up to a 45% ATK increase, which greatly enhances her overall damage potential.
However, the second part of the light cone’s passive, which involves boosting damage after inflicting Weakness Break, doesn’t directly benefit Rappa’s Break DMG. Instead, it contributes to her regular damage modifiers, which are not as critical to her kit compared to her Break-focused abilities. Thus, while it has some synergy,Night on the Milky Wayisn’t fully optimized for Rappa’s specific playstyle but can still be useful in certain scenarios.

529
Increases the wearer’s ATK by12%. After using an attack, for each enemy target hit, additionally increases ATK by8%. This effect can stack up to 5 times and last until the next attack. If there are 3 or more enemy targets hit, this unit’s SPD increases by16%, lasting for 1 turn(s).
Eternal Calculusis the best fully F2P option for Rappa, as it can be acquired from Herta’s Store. When maxed at Superimposition 5, it offers a substantial ATK boost, especially incontent like Pure Fictionwhere multiple enemies appear within the same wave.
In addition to the ATK increase,Eternal Calculusalso boosts Rappa’s Speed, a crucial stat for her since it allows her to take more frequent turns, aiding in her Break DMG potential.This Speed boostgives it an advantage over other light cones that focus solely on ATK, as it enhances both her damage output and turn efficiency, makingEternal Calculusa very well-rounded F2P choice for Rappa.
846
Increases the wearer’s Break Effect by28%. After the wearer uses their Ultimate, increases their SPD by8%, lasting for 2 turns.
After the Charmony Fallstands out as Rappa’s best 4-star option, particularly due to its focus on Break Effect, which directly aligns with her kit. Alongside her signature light cone, it’s only other option available that boosts Break Effect for Erudition characters during hte debut of Rappa, making it extremely valuable, however niche. Although it may be somewhat hard to obtain, as it’s a relatively recent Gacha light cone, it shines even more when max superimposed, with the Break Effect buff becoming comparable to that of Rappa’s signature light cone.
In addition to boosting Break Effect,After the Charmony Fallalso grants a Speed increase after Rappa uses her Ultimate, much likeEternal Calculus. This added Speed allows Rappa to take more frequent turns, making it a well-rounded and more budget-friendly alternative to her signature light cone, especially for players who don’t want to heavily invest in a 5-star option but still want tomaximize her Break DMG potential.

Increases the wearer’s Break Effect by60%. When entering battle, immediately regenerates30Energy. After the wearer uses Ultimate, obtains “Raiton.” After using 2 Basic ATKs, advances the wearer’s action by50%and removes “Raiton.” After the wearer uses Ultimate, resets “Raiton.”
Ninjutsu Inscription - Dazzling Evilbreakeris Rappa’s best light cone option and, as her signature, offers the most synergy with her kit. This light cone significantly boosts her Break Effect, making it invaluable for maximizing her Break DMG, the core of her playstyle. Additionally, it provides a small amount of energy at the start of the battle, which is crucial for enabling her to activate her Ultimate early, further enhancing her combat effectiveness.
While this light cone doesn’t offer a Speed increase like some other options, it compensates by advancing Rappa’s action forward, allowing her to potentially take multiple actions per turn.
