Rappa Stats

Is Rappa Worth Pulling?

Rappa is a Erudition DPS who excels in dealing a lot of Break DMG on multiple enemies with her Sealform state. While in the Sealform state, Rappa gains increased Break Efficency and Break Effect.

Despite not having the ability to implant a missing Weakness, Rappa can reduce the Toughness of enemies by using her Enhanced Basic ATK in her Sealform state.

Pull for Rappa if you need a Break DPS who specializes in AoE content. Rappa will work effectively in Pure Fiction but will struggle against Elite enemies.

Rappa's Best Builds

Break Effect DPS

Most of Rappa's DPS will come from Break DMG, so CRIT Rate and CRIT DMG stats are unnecessary. Aside from Break Effect, the ATK stat is also important since this will increase Rappa's Break DMG on Weakness Broken enemies.

Recommended Stat Values

Stat	Recommended Value
ATK	3200 or above (during combat)
Break Effect	250% or above (during combat)
Speed	Any SPD Breakpoint above 145 SPD

Rappa should aim for 3200 ATK to max out the Break DMG conversion provided by her Bonus Ability (Ninjutsu Inscription: Withered Leaf).

Rappa should also have 250% Break Effect to activate the full-set effect of the Iron Cavalry relic. Characters and Relic sets that provide Break Effect can help you achieve that.

Any SPD Breakpoint above 145 is ideal for Rappa to activate the full-set effect of the Talia: Kingdom of Banditry.

Rappa's Best Teams

Rappa F2P Team (Free to Play)

DPS	Support	Support	Healer
Rappa	Trailblazer (Imaginary)	Asta	Lynx

For any team, Rappa needs the Harmony Trailblazer to increase her Super Break DMG. As for other free-to-play units, you can use Asta to increase Rappa's ATK and SPD, while Lynx can keep the party alive via healing and Debuff Cleanse.

Rappa Super Break Team

DPS	Support	Support	Sustain
Rappa	Trailblazer (Imaginary)	Ruan Mei	Lingsha

Rappa and the Harmony Trailblazer will work together in dealing a lot of Super Break DMG to enemies.

Ruan Mei provides more Weakness Break Efficiency, Break Effect, and can extend the duration of Weakness Break to give everyone more turns dealing Super Break DMG. Lingsha is the best choice for sustain since she can do AoE healing and increase Break DMG received by enemies.

If you're using an Abundance unit for Sustain, we recommend equipping them with the Quid Pro Quo Light Cone to provide energy for Rappa's Ultimate.

Rappa's Best Relics and Ornaments

All Recommended Relics and Ornaments

Relics	Rating & Merits
Iron Cavalry Against the Scourge x4	★★★★★ - Best Iron Cavalry Against the Scourge is Rappa's best relic set since it improves Break and Super Break DMG by ignoring a Target's DEF stat.
Thief of Shooting Meteor x4	★★★★☆ - 2nd Best Thief of Shooting Meteor provides a big amount of Break Effect. It can also restore Rappa's energy when she inflicts Weakness Break on an enemy but its usefulness in helping you recharge your Ultimate faster depends on how many enemies you are breaking.
Iron Cavalry Against the Scourge x2 Messenger Traversing Hackerspace x2	★★★☆☆ - 3rd Best You can use a mix of Break Effect and SPD relic sets if you have better sub-stats on those pieces.
Ornaments	Merits
Talia: Kingdom of Banditry	★★★★★ - Best Talia: Kingdom of Banditry is Rappa's best ornament since it simply provides her with more Break Effect. This requires Rappa to have at least 145 SPD.
Space Sealing Station	★★★★☆ - 2nd Best Space Sealing Station is great for Rappa if you solely want to boost her own ATK, which will also increase her Break DMG in the process.
Forge of the Kalpagni Lantern	★★★☆☆ - Niche Forge of the Kalpagni Lantern is a niche option, but can be great when up against enemies that are weak to Fire.

Rappa's Best Light Cones

All Recommended Light Cones

Light Cone	Why We Recommend It
Ninjutsu Inscription - Dazzling Evilbreaker	★★★★★ - Best Ninjutsu Inscription - Dazzling Evilbreaker is Rappa's signature and best Light Cone since it provides a ton of Break Effect and advances her in the turn order after using her Ultimate.
After the Charmony Fall	★★★★☆ - Great After the Charmony Fall is another Light Cone that provides Break Effect and increases Rappa's SPD after using her Ultimate.
Make the World Clamor	★★★★☆ - Great Make the World Clamor provides a large Ult DMG increase at higher Superimpose levels. It also provides energy to Rappa at the start of the turn to help activate her Ultimate sooner, which can be important for cycle-sensitive content.
Eternal Calculus	★★★★☆ - Great Eternal Calculus provides a ton of ATK stats which can help increase Rappa's Break DMG. It also provides a bit of speed.
Night on the Milky Way	★★★☆☆ - Good Night on the Milky Way provides Rappa some ATK stats for every enemy on the field. This also increases Rappa's DMG when she inflicts Weakness Break on an enemy.

Rappa's Trace Priority

Combat Traces

Trace	Priority & Explanation
Basic Attack	★★★☆☆ - Mid Priority Increases the damage dealt by her Enhanced Basic Attack. Though not a huge increase compared to the Break Damage she deals, it's still useful to upgrade it and squeeze a little bit more damage out of her kit since you'll be using this a lot.
Skill	★★☆☆☆ - Low Priority Rappa's Skill should be prioritized last since it only scales on ATK%.
Ultimate	★★★★★ - Highest Priority Rappa's Ultimate should be maxed out since it increases the Sealform state's Break Effect buff.
Talent	★★★★★ - Highest Priority Rappa's Talent is where most of her DMG comes from since it increases her 3rd Enhanced Basic ATK Break DMG.

Bonus Abilities

Trace	Priority & Explanation
Ninjutsu Inscription: Sky High	★★★★☆ - High Priority Rappa gains a Charge stack and regenerates energy after inflicting Weakness Break on an Elite enemy or higher.
Ninjutsu Inscription: Sea Echo	★★★★★ - Highest Priority Rappa's Enhanced Basic ATKs during Sealform State can deal 1 instance of Super Break. This significantly increases Rappa's damage output.
Ninjutsu Inscription: Withered Leaf	★★★★★ - Highest Priority Rappa can deal more Break DMG on Weakness Broken enemies for every 100 ATK that exceeds 2400. This also significantly increases Rappa's damage output.
