Robin Summeretto Best Build Guide

[Overview]

The new form of Robin is another addition into the 'universal support' archetype we've been seeing more and more of lately. She is a Remembrance Wind character, and can use her Ultimate to action advance a single ally while also restoring a percentage of their Max Energy. After reaching enough of her unique resource, she will take to the stage with her memosprites, inflicting a persistent Vulnerability on enemies, and providing a large variable DEF ignoring Zone, while also having her memosprites periodically launch their own attack. She provides another variable buff for allies through a Bonus Trace, granting ATK to high ATK allies, and CRIT DMG to low ATK allies, making her suitable for both ATK and HP scalers.

[Intro]

A weapon to rival the weapon to surpass Metal Gear?! Mortenax might just have found a worthy peer. And finally, a new Robin song that we can actually hear regularly in-game. It's a bop in my opinion, but it's a bit of a short loop, sadly.

If you've been wondering whether or not a limited edition version of the Remembrance Trailblazer was ever going to show up, then Robin Summeretto is probably the closest thing to that so far.

You get all the things you'd want, including an action advance and large damage amplifying effects, and since Summeretto is a Remembrance character as well, it means she can even slot into setups involving Cyrene, finally getting to make use of the 'Chrysos Heirs and Remembrance characters' line in Cyrene's Recollection passive.

On that note, this Robin actually is the first non-Chrysos Heir Remembrance character, so perhaps the age of Remembrance is not fully behind us just yet.

You'll see why this Robin is probably going to be seen quite a bit in the meta for at least a good little while. I'm also going to just refer to her as 'Robin' or 'Robin SP' in the rest of this review, because I don't have enough whimsy to ignore the red underline under Summeretto.

[Abilities]

As a Remembrance character, Robin SP has a memosprite with its own attacks and passives. Memosprites plural, in this case. Robin's Summer Songbirds.

Robin's Talent explains their presence. The Summer Songbirds have an initial Max HP of 70% of Robin's Max HP, and an initial SPD equal to 180% of Robin's. Whenever an ally attacks, or provides healing or shielding for the first time in any target's turn (including enemies'), Robin gets 1 Vibe. Yes really. Vibes can stack up to 50.

Robin can summon the first of the troupe with her Skill, and if any of the Songbirds are already on field, then using this Skill will fully heal the memosprites and grant Robin 6 Vibes. At 6 Vibes, regardless of how you get there, the next member of the Songbirds is automatically summoned, and then at 12 Vibes, the final Songbird shows up. The number of Songbirds on the field will also determine how much passive Vuln is being applied to enemies; 8% with 1 bird, 12% with 2, and 16% with all three birds.

When all three Songbirds are on the field, any Crowd Control effects affecting Robin are dispelled, and Robin and her birds enter the Fever state, and here's where the music starts. This deploys a Zone that allows allies to ignore 15% of the enemy DEF when dealing damage, plus an additional DEF ignore based on (number of Vibes * 0.5%). This caps out at a 40% DEF ignore in total when at 50 Vibes.

During the Fever state, Robin does not take her normal turn until the Fever state ends, and she and her Songbirds are immune to Crowd Control.

The Songbirds will act in her place during the Fever state, dealing 150% of Robin's Max HP to all enemies on the field. The Fever state has a countdown appear in the turn order, with an initial SPD of 140, this will be important. This Fever state also increases Robin's and her birds' DMG dealt by 60% + (Vibes * 2%), up to a total of 160% amp at 50 Vibes.

When the countdown reaches 0, 50% of the current Vibes will get deducted, with a minimum deduction of 12 Vibes. If Vibes reach 0, the Songbirds disappear and the Fever state will end.

You can see that it's important to be generating enough Vibes in between the countdowns so that Robin doesn't ever have to exit the Fever state, and this will also affect the variability of the DEF ignore she provides while singing. Choosing when to have your team burst and when to hold off based on the current Vibes and the upcoming Vibe deduction will be key to maximising the performance of Robin within your teams.

The Songbirds will generate 20 Energy for Robin when they are summoned via the Skill (doesn't apply to the auto-additions from Vibes), so there's an extra injection of Energy at the start of combat, and should the Songbirds leave the field for any reason, Robin's next action advances by 50%, so she should be able to get back into her groove fairly quickly, especially since she'll get the extra Energy again.

But of course, this Energy needs to be used somewhere. For the cost of 140 Energy, Robin SP allows you to fully action advance an ally of your choice (besides Robin SP herself) and will additionally regenerate 20% of that ally's Max Energy.

This will also grant the affected ally and their memosprite the Special Guest effect, allowing their attacks to generate an additional 2 Vibes. The Special Guest effect will also prohibit the affected ally from action advancing any other friendly units. I know, it's a buzzkill for potentially funny setups, but it somewhat keeps parity with the way the other action advancing limits work. My fellow CBT2 and CBT3 players remember Unlimited Bronya Works, and we've been paying for that momentary high ever since...

The Special Guest effect lasts for 2 turns, and decreases by 1 at the start of the affected character's turn, so you can consider this to be particularly effective at stacking Vibes for characters who attack a lot outside of their turn, or who have memosprites to attack for them.

This Ultimate is extraordinarily potent because it allows you to essentially bank a full action advance and use it when it's most appropriate for you — but that's not even the best part, no no, the best part is that this Ultimate does not have any explicit benefits for the affected ally. All the amplifying effects happen automatically, and for everyone on the team, so why's that important?

Because you get to advance anyone you want or need. I mean, within reason right, there's the limit for other action advancers. But mostly it's anyone, and this can let you come up with extremely carefully tailored rotations where perhaps it'd be optimal to advance the sub-DPS or secondary support to allow them to act before the main DPS; or perhaps to give a large Energy injection for an important Ultimate to be reapplied before Big Money™ attacks start to go out.

It's an incredibly versatile Ultimate, and having complete control over its activation is utterly invaluable, for both casuals and sweats alike. This is probably the biggest upgrade Robin SP has over the Remembrance Trailblazer, as while Mem's Support is incredibly powerful and can lead to funny numbers as any 0-cycler can tell you, it's also a colossal pain in the posterior to align with important actions, and many a reset has happened because Mem got to 100% a turn too early.

I'm getting very excited now.

[Bonus Traces]

But I'm not done yet! Robin's A2 will provide further buffs to allies who provide Vibes to Robin; if the ally's ATK is higher than Robin SP's, that ally's ATK is increased by (16% + (Vibes * 0.4%)) of Robin's Max HP. If the ally's ATK is LOWER than Robin's, they will instead gain (40% + (Vibes * 1.5%)) bonus CRIT DMG. The bonus lasts for 2 turns, but realistically it's permanent after the first application.

I know, I know, 'Oy guv, wot's this maths malarkey doin' in 'ere?'. Blame Hoyoverse for presenting variable buffs in this form. To put it into better perspective, if Robin SP has a fairly reasonable Max HP of 8000, and your Vibes are at the max of 50, an ATK-scaling ally would be getting 2880 bonus ATK. For a HP-scaler, it'd be giving 115% CRIT DMG. Yeah, I know, pick your jaw up off the floor, we're not done yet.

In case you're worried about the wrong buff getting applied, I must reassure you that that is remarkably difficult to do; Robin SP has rather deliberately the highest Base ATK of any of the Remembrance HP-scalers, and since none of them build ATK, you're always going to have the right buff present no matter what.

The A4 presents a new resource for Robin SP to take advantage of. When Robin or her Songbirds get healing or shielding from an ally, Robin and her birds gain 12 stacks of Groove, up to a max of 12. The first time that Robin gets Vibes on any unit's turn, she will consume 1 stack of Groove to gain 3 Energy.

This is literally just free Energy for doing what you were already doing. This can be seen as sort of an equaliser between sustained and sustainless team setups, so you shouldn't feel overly pressured to play without a sustain for maximum effect here since Robin SP directly benefits from the inclusion of a sustain character (think Green Foxian).

Lastly, the A6 will increase the CRIT Rate of Robin SP and her Songbirds by an additional 50%. Very Remembrance-coded, as you have a lot of stats you actually want and can't always get the amount of CRIT you want, so this elevates Robin SP's already pretty noteworthy personal damage.

[Eidolons]

You do not need them, but they're nice to have, and as always, at least in recent times, the first couple are particularly enticing.

E1 will allow the Songbirds to record 100% of the non-True DMG dealt by allies, and then when the Songbirds attack, they additionally deal True DMG equal to 11% of the recorded value plus (Vibes * 0.1%) to the enemy target with the highest HP. After this attack, 50% of the recorded value is cleared.

This is essentially a mini Cipher as an Eidolon, and that's... Well that's pretty ridiculous I won't lie. It is only to the highest enemy, but with a maximum return of 16% of the stored value, that's extraordinarily potent, and is just ANOTHER way that Robin SP buffs the whole squad. Very high value.

E2 will increase the All-Type RES PEN of allies by 18%, and the maximum number of Vibes increases to 70. The first time an ally uses an ability that would grant Vibes to Robin, she gains an extra 2 points.

This skyrockets the speed of Vibes stacking and has the bonus of increasing the upper limit of the variable buffs due to having the Vibes stack count increased as well. And of course, RES PEN, because *of course*.

E4 will grant 12 Vibes instantly upon entering the Fever state, and the SPD of the Songbirds increases by 20% + (Vibes * 0.5%). Slightly more ramp-up, and faster attacks coming out of the Songbirds.

Finally, the E6. The Songbirds' AoE attack has its DMG multiplier increased by 100% of its original value — a full doubling of the final damage — and while in the Fever state, Robin can store her Ultimate up to 2 times. After entering the Fever state for the first time, or at the start of a Fever countdown turn in this fight, Robin regenerates 140 Energy. A literal full Ultimate at no extra cost.

It's an E6, but holy hell.

[The Rest]

It's pretty clear to see that Robin Summeretto is a veritable powerhouse of a support. She's immediately joining the likes of Mortenax and Welt as de facto 'put that stuff on everything' units that just WORK and don't really need all that much help.

Compared to them, Robin SP is substantially easier to actually play at a baseline, since, well, after you enter the Fever state, she's functionally just a Currency Wars backup character, doing her own thing without your needing to intervene. The only thing you do actually need to somewhat care about is her Ultimate and when you use it.

And so, this is what I'd say the 'skill limit' of Robin SP is: where you use her and who you pair her with. That Ultimate is crazy high value, this is fairly indisputable, but depending on what happens in a fight, and considering that the action advance and Energy restore can be granted to (almost) any ally, you may need to work unexpectedly hard to figure out what the best time to use it is.

Consider this example: if you're using Robin SP on a full follow-up team, think Ashveil and Mortenax, then you're not really going to be struggling for much at all, you'll mostly be topping up Ashveil's Ultimate and granting him the Special Guest effect for faster Vibes stacking as well, and you'll be hitting the max of 50 Vibes with little effort. But if you want to use Robin SP on a team like Saber Gilgamesh, somewhere she is greatly appreciated, well now you have to add on Robin's nuances onto the extremely large mountain of headache that already naturally exists with that team, and choosing whether to Ult on Saber or Gilgamesh is a genuine question that you may need to consider later into the fight.

It's not really a deal-breaker per se, it's just something to keep in mind that Robin SP's difficulty, much like her kit itself, has a high degree of variability.

But there is a larger question that some of you may be thinking of right now, namely 'Do I actually need Robin Summeretto though'. You may say this actually depends on what other units you have, both support and DPS, after all, while Robin SP does have the insane universality that both Mortenax and Welt do, she doesn't really properly synergise with any specific archetype. 

Well, bad news for you potentially, but she really is just that strong. Sure, she's not like The Dahlia was for Break, nor is she like the Fate part 2 characters for their respective allies, but she's incredibly strong RIGHT NOW, even if it's not exactly archetype-defining.

Both Mortenax and Welt are in a similar spot, but at least for them they can be much more comfortably be used in place of an actual sustain in teams, providing their immense buffing value while also making it easier to survive, and Welt is even fairly accessible at all times and is easy to get going since everyone gets the Tutorial Light Cone.

Having just the aforementioned two is very good, but they're often on different teams, or sometimes even on the same team, depending on what you're using and going for. Having access to a third universal support option is naturally very good, and further boosts the teambuilding variety you have access to.

This is especially notable for the minmaxers and 0-cyclers who tailor their every individual team to the exact fight before them, leveraging everything they can, and having an omni-amping, Energy regenerating, action advancing support who can even deal some decent damage of her own is VERY good. Even still, you also shouldn't automatically assume that if you're a more casual player that Robin SP won't be very good for you (because she is).

The easiest way to understand why Robin SP is as good as she is, is to return to the statement I made at the start, namely that Robin Summeretto is essentially an upgraded form of the Remembrance Trailblazer. I do not say this lightly, and anyone with eyes knows how strong the Remembrance Trailblazer is, but this should really highlight why Robin is so strong.

As such, Robin Summeretto can naturally fit into any of the teams that the Remembrance Trailblazer was previously in, and she can do so seamlessly. While I'll give some notable examples, please understand that you should experiment for yourself and find what works best FOR YOU, and not to just take my word for it. I believe in you.

Remembrance teams in general are somewhere where the Remembrance Trailblazer frequented, either as a mainstay or as a perfect filler for missing important members. My gal Evernight has been a very powerful performer when paired with Cyrene, as they make a very impressive dual DPS composition that when played perfectly would have both had the Mem's Support buff on them. Putting Robin SP here instead makes it effortless to buff both Evernight and Cyrene, and lets you advance and Energy restore Evernight or Hyacine to ensure that their Ultimates maintain their uptime.

For Castorice teams, surprisingly enough it looks like replacing Cyrene with Robin SP may be the way to maximum damage now (depending on the fight of course, and if you actually have somewhere else to utilise Cyrene), but if you've been staunchly avoiding Evernight or chose to vertically invest in Castorice, Hyacine, and Cyrene, you could also replace Evernight in this team with Robin SP and see similarly great success. With this team, it's harder to justify pulling for Robin SP compared to the solo Evernight comp if you already have every member vertically invested, but you probably can be the judge of that yourself.

Aglaea is the black sheep of the Remembrance teams, but unsurprisingly Robin SP is very good for her too. The only real issue is that Aglaea herself is struggling to stay relevant, even for the most dedicated of players. Very much a case of 'it's not you, it's me'.

For the more prevalent meta teams, the Follow-up archetype as a whole is eating good with Ashveil and Mortenax, and adding in a character who easily buffs the whole team and whose personal resources can be easily stacked by fast attacking characters is pretty obviously good. There may even be a surprise (please act surprised when it happens) addition to the archetype that would also synergise greatly with this Robin.

Elation teams can also benefit from all of the buffs Robin Summeretto is flinging out, and is particularly powerful for Silver Wolf 999, not for directly Ulting Silver Wolf, but actually to advance and regen Yao Guang's Ultimate for more Aha Instants and faster funnelling of Certified Banger to SW999. It's a little harder to make use of Robin SP's conditional CRIT DMG buff for Eva and Sparxie since their base ATK is naturally higher so you're likely going to be stuck with the ATK buff, but even then, it's still a lot of buffing and the same strategy of advancing Yao Guang works wonders if you don't need the Energy for Eva or Sparxie.

This archetype also indirectly benefits from Robin Summeretto, for the reasons mentioned earlier: replacement to the Remembrance Trailblazer. If you had a team that absolutely could not work without that Trailblazer, you'd lose a very potent Elation teammate, and your Elation team could suffer as a result. Now, you can just pull a switcheroo and free up the Trailblazer to pursue the path of Elation. There's that teambuilding versatility I talked about.

Himeko Nova can also make use of Robin SP, again replacing the Remembrance Trailblazer in what is now likely a solo Decimation composition. This is a very, truly greedy setup that has Himeko Nova paired with all three of the big universal supports: Robin SP, Welt, and Mortenax. It's a huge amount of damage, but it can cause you to miss some Assist Skill uses if you're not careful, and as mentioned, it locks you out of the possibility of switching to Verdict, so it may actually end up being less optimal than you think in lower enemy density encounters. Also, again, just the sheer opportunity cost of running this setup makes it personally less enticing, but it really is just that strong.

Probably the other really noteworthy setup is Saber and Gilgamesh. Once again, as you may have already noticed the trend, more than one character responsible for dealing damage and very Energy hungry with high Max Energy, it's a natural pairing.  Of course, like I said before, they are hard to optimally pilot, and now even more so with Robin in the mix, but extremely, extremely rewarding when played well.

[Wrap up]

'Do I need Robin SP?', that's the question posited. No, you do not NEED her, just like you don't NEED Mortenax, or Welt, or any of the other extremely powerful characters. There will be more in future, no doubt about that, but I recommend at least considering that you do.

Especially if you're still rocking the old guard of universal supports like Tribbie or Cipher, those are getting rapidly phased out by these newer and more refined kits. I'm even fairly confident in saying that unless your Tribbie is at E1, you're probably approaching the 'dire need' stage of pulling for new supports.

But I mean hey, you can also look at like this: Tribbie with E1 has survived for an extremely long time, and is only just now starting to be outdone by her new competitors (and even now some people are still arguing that). If you're really playing the long game, going for one or two Eidolons for Robin Summeretto will mean that she gets to see a lot of use and for quite some time.
