Granblue Fantasy: Relink – Endgame Rosetta Guide: Build + Tips

Endgame Rosetta Guide

Build

Stats and V+ sigils. I would use Linked Together V+ in place of one of the Supplementary Damage Vs if I had any good ones.

Dual character sigil cut off at the bottom.

Wrightstone. Ideal would be Crit 10, Damage Cap 7, Damage cap 5.

Overmastery. Unfortunately SBA Cap is a wasted slot but the other 3 were perfect rolls, so I kept it.

General Notes

Disclaimer: it is true that Supplementary Damage does not work with her rose auto attacks, but I will elaborate on why I still use it in the sigil section of this post.

You do not want to animation cancel Spiral Rose with a dodge because there is also pulsing damage which originates from Rosetta herself. But you can if you need to dodge an attack. It is better to lose dps than it is to die and have your roses despawned and their levels reset.

As a follow up to the above point, Iron Maiden will cause that pulsing damage from Rosetta to proc extra rose auto attacks during her own auto attacks, link attacks, SBAs, and most importantly Spiral Rose. This is absolutely massive; with 3 roses, my Rose Tycoon –> Spiral Rose combo goes from 1.3 million damage without iron maiden to 2.4m with it. That adds up a lot during link time where you can potentially get 3 Spiral Roses in one Iron Maiden window with maxed out Quick CD.

Do not use her aerials just because they have faster animations. After 4 grounded normal attacks, Rosetta’s Y/right click combo finisher will trigger extra rose auto attacks and this is a significant portion of her consistent dps.

The ideal skill setup for damage is Rose Tycoon, Iron Maiden, Spiral Rose, and Love Lost. If the boss moves around frequently then Bouquet can be used to help with repositioning roses, but I find that Iron Maiden will still net you more damage in the long run, especially during burst phases like Proto-Baha SBA stunlocks or link time. If you proc link time even once, Iron Maiden should net you at least 4m additional damage varying with the length of the link time extension, and you would need to have horrible rose auto uptime to lose out to Bouquet.

My overmastery roll might look perfect, however, it isn’t. SBAs have high and difficult to reach damage caps already so SBA damage +20% or attack +1000 would be preferable to SBA cap. Wanted to mention this because I’ve seen some people here recommend crit rate + all 3 damage caps on overmastery when SBA damage cap is mostly irrelevant.

Contrary to popular belief, attack buffs aren’t completely useless despite the damage cap conundrum. For those unaware, buffs will not raise the damage cap, thus any attack that is already capping is not benefitting from buffs. Even so, SBAs and link attacks have absurdly high damage caps and the attack buff will add a significant amount of extra damage to them. As an example, my Rosetta’s SBA deals 1.4m damage without the attack buff, but 1.53m with it. Her link attack deals 583k without it and 653k damage with it. That’s around a 10-12% damage increase on every SBA/link attack FOR THE WHOLE PARTY. This damage adds up since the attack buff can be permanent, especially during long burst windows where 4 SBAs and 4 Link Attacks (potentially 8) are used. The reason other characters generally do not bring attack buffs is because it’s simply not worth running them when they can run a different skill to do damage with instead as it will be useful both inside and outside of burst windows. However, Rosetta’s attack buff is not only functionally permanent but also built into her base kit; it doesn’t take up a skill slot and is very valuable because you’ll always have it active whereas the cooldown of other character’s attack buffs significantly hamper their overall effectiveness. The attack buff also helps to cap the rose auto attacks along with Catastrophe, Tyranny, and Stamina. Without the attack buff her roses will fall 2-3k short of the cap.

The rose auto attacks also have a low motion value but moderately high damage cap. My build does not damage cap with the roses unless I have the attack buff up (32.6k with the attack buff and 27-29k without it). Everything else caps easily in comparison.

With the above information, I would recommend having the attack buff up most of the time, then switching to defense during bloodthirst phases since the boss becomes immune to SBAs and stun. It may help your team survive oneshots in some proud difficulty content, but likely not. If your teammates are dying frequently outside of bloodthirst the defense buff probably won’t be of much help. Regen is ultimately worthless in endgame because everyone runs potion hoarder and is fully capable of healing themselves, not to mention the sheer amount of time it would take to heal someone from low hp to full just from regen. It can be nice to have to ignore some DoTs like burn or blight but everyone will just blue pot through those anyways.

At a moderate investment level, roses at level 1 will hit the Lost Love damage cap. This is not really relevant because there are other reasons you want to level up roses such as the increased auto attack range and hit count. My build caps the level 1 roses at 652,792 + 130,558 damage.

Sigils

First things first, you may notice that I run Supplementary Damage V sigils despite it not working on the rose auto attacks. While that is true, it DOES work on Rosetta’s own basic combo, Love Lost, and Rose Tycoon. While it does not work with the rose pulses from Spiral Rose, it does work with the portion of Spiral Rose that originates from Rosetta herself.

Rosetta’s simple 4 left click –> right click ( I believe this is XXXXY for controller) combo chain with my build does 540k without supplementary damage and 700k with it. That’s 160k from Supplementary Damage every single time the combo is performed.

Love Lost hits for 652k +130k capped. x3 for 3 roses and that’s 390k Supplementary Damage per skill usage.

Rose Tycoon’s Supplementary Damage is fairly negligible, but it exists. It does 97k + 19k, so with 3 roses that’s 60k Supplementary Damage per skill usage.

Essentially, supplementary damage is contributing at least a couple million damage that I would otherwise not have in a quest. Considering I am already damage capping there is not really anything else I can run besides Link Together V for party utility or Glass Cannon V to do more damage, but I will only run that in Proto-Bahamut because that is the only endgame fight where I am 100% confident I will be unscathed.

Sigil Substitutes: (some may be preferable under certain circumstances):

• Combo Booster is not better than Tyranny or Stamina, so it is hard to fit it into your build.
• Life on the Line gives you the same attack as Tyranny at an equivalent level, but without the HP penalty. If you don’t have space for Aegis and don’t have it on any V+ sigils then this works as an alternative, just make sure you are below 45k hp for catastrophe. Tyranny V+ is just easier to farm since Proto-Bahamut drops it often.
• Link Together is really nice for party utility, especially in Proto-Bahamut to push for sub 3 minute link time kills. It is better to run a Link Together V+ over one of the Supplementary Damage Vs, but unfortunately I don’t have any good ones.
• Concentrated Fire does not work with the rose auto attacks, thus they are classified as melee despite having a relatively long range at level 4.
• Insult to Injury is bad because her poison uptime is not 100%, it’s around 50% relative to Rose Tycoon’s cooldown. Not to mention you usually won’t be using Rose Tycoon on cooldown anyways, it’s typically saved for when you need to reposition the roses.
• Glass Cannon is obviously good to push the damage cap higher, but punishes you hard for getting hit. Dizzy resistance does not negate the glass cannon stun, but potent greens can if timed properly. Together with potion hoarder and defensive utility like improved guard on some of your V+ sigils it can be a strong option if you play around it.
• Likewise, Berserker is an option but I find my guard usage to be fairly high considering how close to the enemy you have to be to hit Rosetta’s portion of the Spiral Rose damage, as well as using the dodge to animation cancel when I’m about to get hit by something.
• Quick Cooldown is very good in general gameplay. It feels nice to be able to reposition the roses more often on movement heavy bosses. The Proto-Bahamut fight is extremely scripted and cooldown is relatively unnecessary due to downtime segments, but with maxed out cooldown you can perform a triple Spiral Rose combo under one Iron Maiden buff during link time. The first 15 trait levels of Quick CD provide 10% CDR, but the next 30 trait levels provide the same amount for a total of 20% CDR. If you do not have any usable V+ sigils with Quick Cooldown as a secondary trait, then I would recommend swapping out one of the Supplementary Damage sigils for Quick CD V. Otherwise the goal is to get 3 different V+ sigils with Quick CD as the secondary trait for maximum effectiveness.
• Cascade doesn’t work on Rosetta’s roses, she shares this problem with some other characters.
• Uplift can be very good since Rosetta has solid SBA charge rate when she has high rose uptime. She can’t compete with Ferry but she can definitely turbo-charge the SBA gauge too.

As for the rest of the build, everything is pretty standard and I don’t think there’s anything I really need to point out since there’s an abundance of youtube content about optimal dps sigils. Feel free to ask anything in the comments if you want a better explanation. I will give my opinion on any other sigils if asked, though any sigils not mentioned here will not have been tested by me unless I just forgot to include it. I do not claim to be 100% knowledgeable in every aspect of the game.

Room for Improvement

There are a couple things I could do like roll Damage Cap on a Crit Rate V+ sigil or moving Aegis/Potion Hoarder to Tyranny V+ and Damage Cap V+ in order to free up a slot for Link Together V+ or Stamina V+ with another nice secondary trait. Supplementary Damage V+ feels rarer than the overmastery roll I got so I’m not even going to think about it.

I can also dream about getting a crit rate 10 + damage cap 7 + damage cap 5 wrightstone to get rid of a damage cap sigil and free up another slot, but that is also unrealistic. I am not willing to ever reroll my overmastery, but it would be better to have SBA damage +20%, chain burst damage +20%, or attack +1000 instead of the SBA damage cap +20% because it already has an extremely high cap as mentioned before. Attack +1000 would be the best of those because it would contribute to both SBA and link attack damage rather than just SBA.

That attack is also added before attack modifiers like Tyranny so you are actually getting more than 1000 attack out of it.

Proto-Bahamut Optimization

Rosetta is super easy to play in Proto-Bahamut runs since the burst phases are predictable. The roses are super satisfying to place properly and Rosetta excels in fights with minimal boss movement.

There are several ways to optimize the encounter:

• Use all your blue pots at the start to get an earlier link time, and hopefully you are aware of 2+2 SBA stunlock by now.
• Do not use any skill on crystals, it is completely unnecessary and will hurt your burst dps on Bahamut. UNLESS you are in a premade party and know you have sufficient dps already, then you can spread out the roses across the ship to cover all of it and use spiral rose to clear elemental crystals faster. Premade parties would usually opt for easier crystal clearing strats like Eugen or Io but that’s not important, play what you want to play.
• Level up your roses to 4 using the first purple crystal that spawns on your side of the ship. Hopefully your allies do not blast it immediately. You can then evenly space them out to cover the entire ship or place all 3 in the same spot on one half of it. I generally do the latter then stand in the middle so I can take care of both sides.
• As for the elemental crystals you need to destroy to knock down Bahamut, the half ship plant spots have good coverage of those too. The wind crystals are close enough together that you can hit both of them with your basic combo if you angle yourself in line with both of them. I think you can do the same with the blue crystals but the camera angle gets weird and it’s hard to get the proper angle, so I don’t bother doing it. When you see the red danger pulse from the orange center crystal, dodge backwards before it comes out then dodge back into it and continue your combo. Also dodge if Bahamut tries to take a swipe at you.
• She easily does enough dps to contribute to hitting damage thresholds like the first 80% to trigger skyfall, even on an ascension weapon. I managed to get 7% of it solo with my current build. When you factor in turret damage as well she definitely carries her own weight. Her burst dps is already decent and her consistent dps is also decent when the roses don’t need to be moved around much.
• During skyfall you can preemptively replant your roses up front where Bahamut’s hand will drop while avoiding the beam, but be careful because Rosetta moves forward a little when she plants roses. Dodge backwards as you do this to avoid moving into the beam. (Don’t ask why I know this). This is the tiniest of optimizations (Rose Tycoon will be up anyways) so you can ignore this but it gives you something to do that no other character can. If your party struggles to get the link attack on Bahamut’s hand at this part, then you can save Love Lost from the previous dps window to use here because of its high stun value.
• There is not much else to comment on since the rest of the encounter is pretty much the same, (and on a good run is over on the next dps window) but Rosetta has fast SBA generation and it has pretty far reach so when you do the 2+2 SBA she is a solid initiator for either of the two bursts. Do note that you will have to cancel Spiral Rose to use your SBA if you time Spiral Rose badly. DO NOT be the first SBA if there is a competent Ferry player on the team, they have incredibly high SBA generation with their launch + plunge attack spam with uplift. She can turn the 2+2 SBA into a 1+3+1 SBA dps window.
• You can preemptively plant your roses on the bow of the ship prior to Bahamut’s enrage sequence, but again that is an extremely tiny optimization and if the fight has already gone on that long there is little point in optimizing it further to save what would amount to be a few milliseconds.

You can skip past this paragraph and all of these images if you believe me when I say Rosetta is perfectly fine in endgame content. Or look if you want to see decent Baha clears anyways.

If anyone is curious, I typically finish Proto-Bahamut runs with 13-14m honor, almost always as MVP. I tried running the fight solo to test my damage contribution and I can knock off 7% of the first 20% dps check prior to skyfall (without glass cannon/berserker). I am not really sure how honor is calculated since it is not 1:1 with damage dealt obviously (I do more than 14-16m damage in a single extended 2+2 SBA + link time window), but I suspect it is similar to FFXIV rdps in some aspects.

Except in this instance I am somewhat inclined to think the game grossly overestimates the value of support buffs, probably not accounting for the damage cap. MVP is pretty meaningless either way, but I just wanted to point out that Rosetta is perfectly fine to play in endgame. Having a good build and playing optimally will still outperform the majority of online players even when they are playing characters with much higher potential dps. Below I’ll show the next few clears I get as I’m writing this guide.

Average sub 5-minute clear. A couple of repeats.

Same kill time as above, but 5m more honor for some reason. Not really sure what contributes to honor but I can only assume some of my party didn’t hit their damage caps so their increased damage from the attack buff was pooled into my honor. Some more repeats happened.

Sub 3-minute kill. Rosetta is fine in 2-3 minute speedkills, but probably doesn’t have the dps for the 2 minute kills with Ferry’s 1+3+1 SBA tech. I’ve never tried it though so I couldn’t tell you.

My 60s score attack with the supplementary damage build peaks at 18m damage. This is not very accurate as to Rosetta’s true dps because aerial hitstun forces Rosetta to delay her attacks to keep the training dummy grounded, and her Rose Tycoon poison gets confused by unlimited hp. Somehow I don’t have Glass Cannon V yet, so this won’t be the fairest comparison, but 60s time attack with Glass Cannon IV substituted for 1 Supplementary Damage V dealt similar damage, so I can only assume Glass Cannon V is a significant gain. (No supp damage or glass cannon was 16m, for reference).

Evidently, Rosetta is far, far away from being a ‘bad’ character, but we can still acknowledge that she isn’t close to being the best. That’s okay though.

Closing Remarks

I don’t want to cope too hard and deter anyone from playing my favorite character, but there are important things to put into consideration that I would like to convey to people looking to play Rosetta. Honestly I can see why she has such a small playerbase despite having a very attractive character design. Both her damage and utility are currently flawed. My Narmaya with no terminus weapon, no supplemental damage V, horrible overmastery, and no wrightstone does better dps.

That would be fine if Rosetta’s supportive capabilities were more impactful, or if Mesmerize worked properly on bosses, or if her party damage cut skill was an invulnerability instead to give her greater utility. Any other form of crowd control like dizzy, paralyze, or slow would also make her a better support-oriented character. In her current state her utility aside from the attack buff is not at all valuable in endgame and unfortunately the uplift support playstyle has better candidates (Ferry). It doesn’t help that Rosetta is also one of the more punishing characters upon death since her roses get despawned and have their levels reset.

I don’t know if Cygames will ever do balance changes, but I hope that in the future they allow supplementary damage to apply on rose auto attacks. This alone would boost her damage by at least 480k per iron maiden + spiral rose usage (20% of 2.4m), not to mention subsequent auto attacks. She would still be significantly lower dps than the other characters but that would be fine if they also add very small damage cap to her attack buff so she can play a more supportive role successfully. They could also significantly raise the damage cap of Love Lost with level 4 roses, because as it stands it will likely cap at level 1 for anyone with a proper build.

This makes the damage increase for higher level roses pretty negligible and doesn’t make much sense. It’s a similar situation to Narmaya and Io not charging Setsuna and Flowery Seven respectively because the uncharged versions already hit the damage cap. I would love to see her gain a party invuln on Rose Barrier or maybe a dizzy on Love Lost to improve her utility as well, but one can only hope. Bouquet should also give temporary debuff immunity IMO. My main argument is that if you sacrifice all her damage for utility, that utility should be much more impactful than it currently is. Any sort of cooldown reductions to Rose Tycoon and Spiral Rose would also help push her damage up a little and would in general be nice for repositioning roses for better uptime. All I’m saying is that it would be nice if she provided more value to a team.

For those interested in knowing damage cap math, I would encourage you to head over to the GBF Relink discord and navigating to the Rosetta channel. There’s plenty of good info there I haven’t seen shared anywhere else.

If you have read this far, I hope you have a better idea of Rosetta’s mechanics and can show people what she is capable of. If you still have any questions I am open to answering them. I know I use a bunch of RPG jargon and abbreviations and I will happily explain them to anyone newer to the genre. Thank you for taking your time to read this, and please do comment any corrections or anything you would like to add that you think I did not cover sufficiently.

TLDR

Rosetta’s attack buff specifically is better than the average person would think. It improves the entire party’s link attack + SBA damage as well as helping your rose autos hit the cap. Supplementary Damage doesn’t work with rose autos, but I would still recommend it for her basic attack chain and Love Lost. The only other substitution I would consider for Supplementary Damage would be Glass Cannon + Link Together V+ or other sigils with Quick Cooldown or Uplift as secondary stats.

Alternatively you could choose to be really tanky with stout heart + steel nerves + crab vestments (make sure to stay under the catastrophe threshold) but I don’t think anything in the game is difficult enough to warrant having that much damage reduction. Unfortunately her utility is rather lacking and her dps is not anything to write home about.

Regardless, she is still a fun character to play and functions perfectly fine in current endgame, so don’t hesitate to build her if you enjoy her playstyle!
