Robin - Summeretto is an amazing universal support who fits into almost any team. She can buff her allies' ATK or CRIT DMG depending on whether they have higher or lower attack than her, so she fits into ATK or HP-scaling teams.
Her Vibes mechanic pairs well with characters that can attack or move consistently like Ashveil, Hyacine, and others. She provides DEF ignore, a damage amp, offensive buffs, and even deals a good amount of damage herself thanks to her Summer Songbirds.
If your account lacks universal supports, then Robin - Summeretto is worth pulling for. Even if you have a lot of supports, she is still worth pulling for since she functions at base investment and can free up your other supports for other teams easily.
Robin - Summeretto's Light Cone, Rise and Sing, gives her a lot of Max HP. This allows her to give a bigger ATK buff to the DPS, while also allowing her Songbirds to deal more damage. The SPD buff is good too since it allows to adjust how the team's SPD is built, taking the boost into account.
The SPD boost alone can let characters hit certain speed breakpoints that they might need for an extra action or two in a cycle. However, the other things the Light Cone provides is minimal and can be skipped over.
Robin - Summeretto benefits greatly from her signature Light Cone, but also has other options in Memory's Curtain Never Falls and The Story's Next Page. She can even use non-Remembrance Light Cones, provided that they have high base HP.

As a support, Robin - Summeretto's best Relic set is World-Remaking Deliverer since it increases her and her memosprite's Max HP. It also lets her buff her allies' damage. The CRIT Rate increase also increases the damage she can deal through her memosprite.
Robin - Summeretto's best Planar Ornament is Amphoreus, The Eternal Land, since it increases her CRIT Rate and lets her buff the team's SPD, giving them more turns.
Robin - Summeretto wants HP% and SPD stats to increase the ATK buff she provides and so she can hit certain speed breakpoints.
| Stat | Recommended Value |
|---|---|
| HP | 6000 or above |
| CRIT Rate | As close to 100% (In Combat) |
| SPD | 160 SPD or higher |
For Robin - Summeretto's HP, prioritize getting at least 6000 HP to boost the ATK buff she can provide for the team. For CRIT Rate, try to get as close to 100% CRIT Rate in combat. Robin - Summeretto gets 50% CRIT Rate from one of her Bonus Abilities and even more from her Relics, so it shouldn't take a lot of substats to get her CRIT Rate up.
Robin - Summeretto is good at the 160 SPD breakpoint because it allows her to summon her memosprite early and get more turns for them, resulting in more damage. The more SPD she has, the more hits her birds can do.
| Support | DPS | Support | Sustain |
|---|---|---|---|
Summeretto
|
Any ATK/HP scaling DPS |
Mortenax Blade
|
Any Sustain character |
This is an example of one of Robin - Summeretto's F2P teams.
Robin - Summeretto is a universal buffer who works with both ATK and HP scaling teams. Pair her up with Mortenax Blade, who is also a general debuffer. Robin - Summeretto gives the DPS either an ATK or CRIT DMG buff and provides DEF ignore for the team. Her Songbirds also increase the DMG enemies take.
Mortenax Blade provides DEF shred and more damage increases for the team. Having any sustain character can help generate Vibes for Robin, along with healing both Mortenax Blade and the DPS.
| Alternative | Explanation |
|---|---|
Permansor Terrae | Sustain Option Permansor Terrae buffs the ATK of the DPS and provides shields for the team. He can also give the DPS a summon. |
Huohuo | Sustain Option Huohuo provides ATK and Energy for the team, along with healing and cleansing debuffs. |
Asta | Support Replacement Asta provides even more ATK for the team and boosts the team's SPD. |
Trailblazer (Ice) | Support Replacement The Remembrance Trailblazer is also a good option, giving the DPS more turns and allowing them to deal True DMG. |
| Support | DPS | Support | Sustain |
|---|---|---|---|
Summeretto
|
Serval
|
Asta
|
Natasha
|
For beginners who don't have any limited 4-Star or 5-Star characters yet, Robin - Summeretto can still be used as your main support in the team. Serval acts as the team's DPS, while Asta buffs the team's ATK more and boosts their SPD. Natasha provides heals and cleansing for the team.

These are samples of Robin - Summeretto's ATK teams.
Robin - Summeretto increases the character's ATK if they have higher ATK than her. This makes her great in teams where the main DPS is ATK scaling. She also provides DEF ignore for the whole team and increases the damage enemies take.
She can easily duo with other hypercarry supports and increase the damage of the team immensely. For sustainless teams, she can replace the sustain character themselves instead of another support.
| Alternative | Explanation |
|---|---|
Permansor Terrae | Flex Replacement Permansor Terrae buffs the ATK of the DPS and provides shields for the team. He can also give the DPS a summon. |
Sparkle | Flex Replacement Sparkle provides turn advance and SP generation for the Archer team. She can also be used in the other teams as another hypercarry support. |
Trailblazer (Ice) | Flex Replacement The Remembrance Trailblazer is also a good option, giving the DPS more turns and allowing them to deal True DMG. |
Sunday | Flex Replacement Sunday provides crit stats for the DPS and also another turn advancer. He can also be used in other teams as another hypercarry support. |

These are samples of Robin - Summeretto's HP teams.
Robin - Summeretto increases the character's CRIT DMG if they have lower ATK than her. This makes her also great in teams where the main DPS is HP scaling. Again, she provides DEF ignore for the whole team and increases the damage enemies take. You can pair her up with other supports in HP scaling teams and increase the damage of the team immensely.
| Alternative | Explanation |
|---|---|
Cerydra | Flex Replacement Cerydra can replace Hyacine when running sustainless with Mydei for more damage. |
Mortenax Blade | Flex Replacement As a general debuffer, Mortenax Blade can also fit in Mydei's team as a replacement for Hyacine for sustainless. |
