E6A Song Yet UnnamedE1Allows Summer Songbirds to record damage dealt by allies, up to 16% at max Vibes, then unleash it onto the highest HP target during their turns. This damage redistribution is particularly effective in AoE scenarios where there is a main boss focus. This E1 lets you "farm" damage on the adds, and 16% of the damage will be directed to the boss. However, the tally is cleared at 50% instead of the usual 100%, which means that over time the overall damage tallied converges to 32% if max Vibes is reached consistently
E2Increases allies' All-Type RES PEN by 20%, maximum Vibes to 70 while also improving its generation by 2 per turn, allowing Robin to maintain higher Vibes on average. Higher Vibes cap results in a higher ATK/CRIT DMG buff, a higher DEF Ignore effect (from 40%->50%), and raises the damage recorded by the E1, up to 36%. These are strong support Eidolons from the first to second, which can result in a significant performance difference.
E4Provides one-time 12 Vibes upon entering Fever, and substantially increases Summer Songbirds' SPD by up to an additional 55%, allowing it to generate more Energy for Robin, or deal True DMG from E1's damage tally more often.
E6Upon entering Fever and every time the Countdown takes action, Robin gains a fixed 140 Energy, allowing her to immediately use her Ultimate. With the Countdown taking action every 71 AV, the team will see many more Robin Ultimates. Her Max Energy will also be increased to store enough Energy for 2 Ultimates. Effects that activate her Ultimates will grant her 2 charges, while percentage-based Energy Regeneration will see high Energy gains for Robin. Her Memosprite Skill DMG is doubled on top of that.
Castorice pays HP for her memosprite, so the line-up pairs a healer who profits from that with two Harmony units that raise the memosprite’s own damage.

Rise and Sing tops the light cone ranking for Robin • Summeretto at S1, ahead of Long May Rainbows Adorn the Sky, Memory's Curtain Never Falls and The Story's Next Page. That order is prydwen.gg's, measured in play and rephrased here; every row of it sits under Light cones below.
Run World-Remaking Deliverer on Robin • Summeretto, with Messenger Traversing Hackerspace behind it. The planar ornament is Amphoreus, The Eternal Land. Main stats are HP% > CRIT DMG body, Speed > HP% feet, HP% sphere, Energy Regen Rate rope. Roll substats in the order SPD > HP% > CRIT Rate / CRIT DMG.
Trace priority is Ultimate > Talent > Memosprite Talent > Memosprite Skill > Skill > Basic. The Ultimate costs 140 energy, which is what an Energy Regeneration Rate target has to clear.
Robin • Summeretto stands in for Tribbie in the Castorice team, alongside Castorice, Ruan Mei and Hyacine.
Deals Wind DMG equal to 50% of Robin • Summeretto's Max HP to one enemy.
