Gilberta Best Teammates Synergy | Endfield

If you spend any time in Arknights Endfield Discord servers or the subreddit, you have heard the same three-word verdict on Gilberta roughly a thousand times: “best in slot.” She is the universal support, the Arts amplifier, the corrosion enabler, the answer to every “who do I pull next” question. The problem with that consensus is that it is only half true. Gilberta is genuinely best in slot for some carries, a clean sidegrade for others, and an honest-to-god trap pick for at least two of the most popular DPS units in the game. The community discourse smudges those lines because it is easier to call her universally great than to write down the actual list of who she pairs with and who she does not.

This post is that list. We are going to walk through Gilberta’s kit, her weapon priority, and then the operator-by-operator synergy ranking that most tier lists quietly skip. The ratings here come from current calc spreadsheets and rotation testing, not vibes, and a couple of them will probably annoy you on first read. Stick with us — the reasoning holds.

TL;DR - Key Points

Rossi is Gilberta’s best partner, full stop — she was built to enable Rossi’s burst, and the +17% Corrosion timing window is the cleanest payoff in the game
Yvonne pairs well but Perlica matches — in calcs, Gilberta and Perlica trade blows; pick Gilberta if you need the AoE pull or Alesh SP recovery
Awyvenna is the sleeper high-synergy pick — short damage window, easy corrosion routing, and almost nobody is talking about it
Last Rite is a Mid sidegrade — Xaihi and Tangtang are non-negotiable; Gilberta only beats Perlica if you go full LR buff and ditch Tangtang
Laevatain is Low synergy despite the meme — Ardelia is BiS for sustained burn; Gilberta’s inflictions interfere with the combustion cadence
Zhuang Fangyi is Low synergy — single Battle Skill buff, electrification-for-corrosion swap is a net loss
Skip her signature, prioritize Stanza of Memorials P4+ — under 2% gap over Stanza at full investment makes the sig the worst weapon pull on her
Gilberta without a carry to amplify is bench filler — she is a multiplier, not a foundation

Who Gilberta Is (Kit at a Glance)

Gilberta is the Talos-II answer to “what if the entire job description was making other people hit harder.” She is a 6★ Arts striker on the Endfield Industries roster, mechanically positioned somewhere between a buffer and a debuffer, with a side gig in crowd control that turns out to be more useful than it has any right to be. Story-wise she is one of the more talkative members of her unit, prone to dry asides during cutscenes, with a personality that reads less “stoic support specialist” and more “the one teammate who openly tells the carry their build is bad.”

What matters at the table is that her kit was deliberately constructed around enabling other people’s burst windows. Her Battle Skill applies Arts Susceptibility. Her Ultimate amplifies team damage during a tight window. Her core passive triggers Corrosion when conditions are met, and Corrosion is one of the highest-value elemental inflictions in the game right now. The AoE pull on her Battle Skill is the part the calc spreadsheets undersell — it turns three-pack mob fights into one-pack fights and gives the carry behind her a clean line on the cluster.

If you are looking for an operator who racks up the damage column on the post-fight screen, this is not her. If you are looking for the unit whose presence makes the rest of your roster’s damage column visibly bigger, that is the job.

What Gilberta Actually Does in a Fight

The kit is best understood as three timing knobs that all want to fire inside the same window.

The first knob is 42% Arts Susceptibility from her debuff. That is a flat multiplier on every Arts damage instance landing on the marked enemy, and it is the largest single-source susceptibility number on a non-limited support in the current roster. Stacking it under a carry’s Ult window is what produces the “feels like the boss melted” experience that players associate with her.

The second knob is Corrosion application through her Battle Skill. Corrosion is the Arts infliction that, when triggered in alignment with a burst window, layers a damage-over-time effect plus a vulnerability multiplier on the target. On a Rossi setup the timing produces roughly +17% additional damage on the burst when Gilberta’s Battle Skill goes off in the right beat — that number is the one community calcs converge on across the spreadsheets.

The third knob is the AoE pull and brief crowd control baked into her Battle Skill. This is what nobody puts in the TL;DR but everyone uses in practice. In Turbidity Manifest stages with venom pools, in Cryostatic Connection clusters, and across most of Wuling’s mob fights, the pull turns “kite five enemies through three deaths” into “stand here and watch the carry detonate the pile.” It is the single biggest reason newer accounts feel like Gilberta makes content easier even when the math says her damage contribution is small.

Her Ultimate adds a team-amp window on top of all of this. It is short, cheap to cycle, and the entire point of the rotation is to align it with the carry’s burst.

Weapon Priority - Sig, Stanza, or BP Opus?

This is where Gilberta breaks the standard “always pull the signature” template. The math is unusually clear, so let’s get it out of the way.

Skip the Signature

At full investment, Gilberta’s signature weapon delivers under 2% more damage than Stanza of Memorials at P5, and under 5% over a single copy of Stanza. That is the lowest signature-versus-alternative gap in the current 6★ roster. The sig is the worst weapon banner pull in the game right now in terms of return per Arsenal Credit.

Stanza of Memorials (P4+) is the Play

Stanza dumps a team-wide ATK% buff on Ultimate cast, lasting comfortably long enough to cover a Rossi or Yvonne burst window. It piggybacks on the rotation you were already going to run and turns Gilberta’s cheap Ult cycle into a team-wide multiplier. P4 is the threshold where the buff scaling lines up cleanly; P5 is a marginal upgrade.

BP Opus Has a Hidden Cost

BP Opus on Gilberta looks tempting because the Arts DMG Bonus column is fat on paper. In practice it requires her to spend Battle Skills on enemies for the proc, which competes with the team’s SP economy. On a Rossi or Fangyi setup, every BS Gilberta spends to feed her own weapon is one fewer cycle the carry gets out of their own rotation. The number bleeds out in team DPS even if her personal column ticks up.

The community-converged answer: Stanza P4+ first, sig only for completionists, BP Opus only in compositions that already have SP to burn. The megathread QA on weapon priority has the longer breakdown.

The Synergy Tier Table

Here is the ranked tier table the rest of this post unpacks. Print it, screenshot it, paste it into your roster planning doc.

Operator	Synergy	Why
Rossi	Very High	Designed-for-Rossi BiS; first Vulnerability + Corrosion + Ult amp
Yvonne	High	Fits the short burst window; Alesh SP pivot; Perlica matches in calc
Awyvenna	High	Short-window DMG + clean team-wide Corrosion routing
Last Rite	Mid	Sidegrade behind Xaihi/Tangtang; only wins on full-LR-buff comps
Laevatain	Low	Ardelia is sustained-DPS BiS; inflictions disrupt combustion pacing
Zhuang Fangyi	Low	Only buffs 1 BS; trades electrification for corrosion (net loss)

The shape of the table is the whole thesis. Gilberta is a top-tier pick for three carries, mid for one, and a structural mismatch for two — including arguably the two most-pulled limited DPS units in the game. That is the contradiction the community discourse smudges over, and the rest of this post explains it operator by operator.

Rossi - Very High (the BiS Case)

If Gilberta has a “designed for this carry” partner, it is Rossi. The synergy is so tight that whole sections of Rossi build guides assume her presence and provide a “without Gilberta” downgrade path as an afterthought. There are three layered reasons for it.

First, the first Vulnerability trigger. Rossi’s burst rotation rewards stacking four Arts inflictions before the Ult window, and Gilberta’s kit lets you slot the first one cleanly without burning anybody else’s rotation. That single Vulnerability stack is worth more than its surface number because it cascades into the Corrosion proc.

Second, the +17% Corrosion timing window. When Gilberta’s Battle Skill fires inside Rossi’s burst beat, the Corrosion DoT plus the Arts Susceptibility plus the Stanza ATK% all stack at the same instant Rossi’s Ultimate detonates. Community damage calcs put the uplift over the same team without Gilberta at roughly +17%, and the math is consistent across F2P and signature variants.

Third, the Ult amp. Rossi’s Ultimate scales aggressively with the multipliers active during her last two hits. Gilberta’s team-wide amp window stacks on top of Stanza’s ATK% to push that ceiling higher than any other support combo currently in the game.

The current consensus best Rossi team is Gilberta + Antal + Akekuri, with F2P weapons landing roughly 4% behind a fully-invested signature build. If you own Rossi and you do not have Gilberta, the Rossi nuke build breakdown walks through what the team looks like without her — it is functional, but the gap is visible.

Yvonne - High (with an Asterisk)

Yvonne is where the synergy story gets honest. The short answer is that Gilberta fits Yvonne’s damage profile well; the longer answer is that she does not obviously beat Perlica in the same slot.

Yvonne’s damage is front-loaded into a short cryo-detonation window built around her ultimate. Gilberta’s amp window and Corrosion timing align cleanly with that window — there is no rotational conflict, no SP starvation, no infliction overwrite. She also opens the door to Alesh SP recovery routing if your team wants it, which is the kind of utility lever that does not show up on a damage column but materially changes how a fight feels.

The asterisk is the calc. Side-by-side spreadsheet comparisons of Gilberta and Perlica in the Yvonne flex slot have them within a couple percent of each other. Perlica’s Electrification path provides a different vulnerability layer that scales similarly to Gilberta’s Corrosion path on a single-target Yvonne burst. In a calc-only comparison, the two are functionally a wash.

So when do you actually pick Gilberta over Perlica for a Yvonne team? Three cases:

Mob clearing matters — the AoE pull is decisive once enemy count climbs past two
You want the Alesh SP pivot — Perlica does not provide it
You already run Gilberta in your other team — gear and weapon investment carries over

If none of those apply, Perlica is the equal pick and you can stop reading this section. Either way, the Yvonne deep dive on rotations and math is the supporting reference.

Awyvenna - High (the Sleeper Pick)

Of every synergy in the table, this is the one the community is going to take longest to converge on, and we think the calcs are clear enough that we are going to push it now. Gilberta with Awyvenna is a top-tier short-window DPS pairing, and almost nobody is talking about it.

The mechanical case is straightforward. Awyvenna’s damage profile compresses into a short burst window, similar in shape to Yvonne’s but with different infliction routing. That compressed window is exactly where Gilberta’s amp and Corrosion timing earn the most marginal damage. The Corrosion application is also unusually clean here — Awyvenna’s kit does not generate competing inflictions that would overwrite Gilberta’s, which is the structural problem Laevatain and Fangyi have.

The result is a team that hits hard, builds quickly, and does not demand a signature investment on either operator to feel functional. Plug Antal or Ardelia into the third slot depending on whether you need amp or sustain, and you have a complete short-window comp that runs on mid-investment gear.

This pairing is undervalued largely because Awyvenna does not have the limited-banner hype of Yvonne or the meta-cementing reputation of Rossi. If you have her and you have Gilberta, build the team. The damage will surprise you.

Last Rite - Mid (the Sidegrade Trap)

Last Rite teams are where Gilberta runs into the first real competition for her slot, and the math is genuinely close enough that “pick whichever you own” is a defensible answer for most accounts.

The structural problem is roster pressure. A Last Rite Cryo team is essentially Xaihi + Tangtang + flex. Xaihi is non-negotiable — her Detonation Unit weapon and Cryo amplification are load-bearing for the entire archetype. Tangtang is nearly non-negotiable too — her Whirlpool scaling and combo enablement give Last Rite teams their characteristic rotation feel.

That leaves one flex slot. The candidates in serious contention are Gilberta, Perlica, and the dedicated LR-buff supports. Gilberta provides her standard Arts Susceptibility plus Corrosion package. Perlica provides Electrification plus vulnerability. In Last Rite calcs the two come out roughly even, which is the same wash we saw on Yvonne.

The narrow case where Gilberta clearly wins is the full-LR-buff variant that ditches Tangtang entirely in favor of stacking Last Rite-specific amplifications. In that build Gilberta’s universality starts to matter more than Tangtang’s archetype-specific contributions. But that is a niche enough comp that it does not generalize to “every Last Rite player wants Gilberta.”

The take: Mid synergy. Functional, sometimes optimal, never the obvious answer the way she is for Rossi. If you have her, slot her. If you do not, do not pull for her specifically to fix Last Rite — the Xaihi build guide shows that the comp’s ceiling is already cleared by its core trio.

Laevatain - Low (the Inflictor Conflict)

This is the heretical part of the post, and we expect pushback in the comments we do not have. Gilberta is not the right support for a sustained-DPS Laevatain team. Ardelia is.

The reasoning starts with what Laevatain’s kit actually wants from a partner. Her damage is built around the combustion mechanic — stacking burn applications and detonating them with arts bursts in a sustained DPS profile that runs across an entire fight, not a compressed burst window. The supports that scale best with combustion are the ones that amplify burn ticks without disrupting the burn cadence.

Gilberta does not amplify burn ticks. She applies Arts Susceptibility and Corrosion, both of which are different infliction routes than combustion. In a pure-Laevatain comp, her inflictions stack alongside but do not multiplicatively combine with the burn DoT, and her Battle Skill timing can interfere with combustion pacing if you are not careful with the rotation. The AoE pull is still nice, but the damage column comes out below an Ardelia variant.

Ardelia, by contrast, was effectively designed to amplify sustained burn DPS. Her kit produces the same shape of amplification curve as Laevatain’s damage profile, and her infliction routing complements rather than competes with combustion.

There is one nuance worth flagging: in short-content scenarios — a quick boss melt where you only get one Ult window — Gilberta’s burst contribution can match Ardelia’s. So the “Low synergy” rating is specifically for sustained-DPS Laevatain play, which is the archetype most Laev players are actually building toward.

This contradicts a common community framing that says “Laevatain teams also want Gilberta.” That framing is a holdover from when Ardelia was less well understood. The current calcs have caught up. If you own both, Ardelia goes in.

Zhuang Fangyi - Low (the Electrification Tradeoff)

The Fangyi case is shorter and the math is harsher.

Fangyi’s kit is built around electrification. Her optimal supports stack vulnerability and amp inside her electric-driven rotation, which has its own internal cadence and Battle Skill economy. Gilberta plugs into this rotation in two ways, and both of them are suboptimal.

First, she only buffs one Battle Skill per cycle. Fangyi’s rotation runs on multi-BS sequences. A support that contributes a single-BS amp leaves damage on the table compared to a support that contributes across the full rotation.

Second, the corrosion-for-electrification swap is a net loss. When Gilberta’s Corrosion procs in a Fangyi team, it overwrites part of the electrification vulnerability stack that Fangyi was already producing. You trade a higher-multiplier infliction (electrification, on Fangyi specifically) for a lower-multiplier one (Corrosion, in this context). The damage column shrinks even though the buff list looks longer.

The proper Fangyi support stack is something closer to Arclight plus Perlica plus a flex, with Antal or Ardelia in the flex slot depending on whether you need damage or sustain. The Zhuang Fangyi team optimization breakdown has the full elemental synergy chart and shows where Gilberta sits — politely, not in the core comp.

Best Gilberta Teams in Practice

If you build around Gilberta, here are the comps that actually deliver on her ceiling.

Team	Carry	Gilberta’s Role	Notes
Rossi Nuke	Rossi	Vuln + Corrosion + Ult amp	Pair with Antal + Akekuri; F2P version ~4% behind sig
Rossi Budget	Rossi	Same as above	Drop Akekuri for Wulfgard if missing
Yvonne Hyper	Yvonne	Short-window amp + AoE pull	Add Xaihi or Alesh; Perlica swap is the equal alt
Awyvenna Short-Window	Awyvenna	Burst window amp + Corrosion routing	The sleeper comp; pair with Antal or Ardelia
Mob-Clear Utility	Any	AoE pull + cheap Ult cycle	The “she makes content easier” comp; not a damage pick

The pattern across the four serious comps: pair Gilberta with a carry whose damage profile is compressed (Rossi burst, Yvonne window, Awyvenna burst) and whose inflictions do not compete with Corrosion. The two carries she clashes with — Laevatain and Fangyi — both have sustained or alternative-infliction profiles that break that pattern.

Who Should Even Be Building Around Gilberta

The synergy table is one thing; what to do with it on your account is another. Five archetypes cover most readers.

Rossi main. Build around her. Stanza P4+, drop her into the standard Rossi comp, do not look back. This is the cleanest single-target investment in the current meta.

Yvonne main. Build her, but only if you do not already have a polished Perlica. The two are interchangeable on Yvonne, and your existing investment should make the call.

Awyvenna main. Build her. This is the sleeper synergy and you have an account-defining short-window team waiting.

Laevatain or Fangyi main with nothing else. Do not build her for those teams. She is bench filler in your current roster, and the resources go further on Ardelia, Arclight, or Perlica respectively. Save her gear investment until you pull a carry she actually amplifies.

Whale account. Build her for the second team. If you already have a fully-built Rossi or Yvonne setup, Gilberta opens a second short-window comp around Awyvenna or a swap-in option for a different element burst window.

The unifying principle: Gilberta is a multiplier, not a foundation. She needs a carry. Decide whether you have one before you commit gear to her. Our Gilberta vs Laevatain pull decision post covers the banner-side decision tree if you are still mid-pull.

Common Mistakes

Forcing Gilberta into a Laevatain or Fangyi team because “she’s BiS.” She is not BiS for those carries. Ardelia and Arclight respectively are.
Chasing her signature weapon. Sub-2% over Stanza at full investment. The worst weapon banner pull on her in the current roster.
Mistiming the Battle Skill. Corrosion has to fire inside the carry’s burst window. Burning BS for the AoE pull at the wrong beat costs more damage than the pull is worth in most fights.
Treating her as a carry. She does not generate enough personal damage to anchor a comp. Pair her with a real DPS or bench her.
Pulling her without a carry to amplify. Multiplier, not foundation. Pull a DPS first, then come back for her.
Spending BP Opus SP cycles to feed her weapon. SP economy belongs to the carry’s rotation, not Gilberta’s personal damage column.
Running her alongside Perlica without a plan. Their vulnerability layers overlap; pick one or carefully sequence them.

Watch List - What Could Shift the Ratings

The synergy table reflects the V1.2 meta as it stands in late May 2026. A few things could move ratings up or down in the next two patches.

V1.3 Camille kit reveal — if his Blood Hunter archetype rewards Arts amplification, Gilberta gets a fourth Very High synergy
Mi Fu confirmation — a Heat-adjacent DPS profile could either lock in another high pairing or create a second Laevatain-style mismatch
Future Arts DPS units — every confirmed arts striker on the roadmap pushes Gilberta’s downstream value up
Ardelia rebalancing — if her amp is touched in a patch, the Laevatain synergy reopens
New endgame modes — multi-team content elevates supports who slot into multiple comps, which is Gilberta’s home turf
Tangtang adjustments — a Tangtang nerf would push Gilberta’s Last Rite synergy from Mid to High

The pattern across these signals: Gilberta’s ratings depend less on her own kit than on which carries enter the meta and which existing supports get rebalanced. Pay attention to the surrounding roster more than to Gilberta herself.

Final Read

The honest version of the Gilberta verdict: she is best in slot for the carries her kit was built around, and bench filler for the carries it was not. The community shorthand of “always pull Gilberta” works if and only if your account is on the upgrade path that includes Rossi, Yvonne, or Awyvenna. If your account is centered on Laevatain or Fangyi, the resources go further on the supports those carries were actually designed for.

The good news is that Gilberta is one of the safest long-term investments in the game. Future arts DPS units overlap with her buff profile, the upcoming patches are projected to add carries who pair with her, and her Stanza-priority weapon path is cheap to complete. She does not power-creep easily because her role is structural — debuffer, amplifier, AoE puller, Corrosion enabler — rather than tied to a single damage type or element.

Pick the right carry, build her around them, skip her signature, and you have one of the cleanest team cores in Endfield. Pick the wrong carry, and you have a great-looking benchwarmer.

Frequently Asked Questions

Is Gilberta still meta in Version 1.2?

Yes, for the three high-synergy carries (Rossi, Yvonne, Awyvenna). She has not been power-crept and no announced V1.3 changes affect her. The “still meta” question is really a question about your account roster, not about her kit.

Why is Gilberta rated Low for Laevatain when most guides say she’s required?

Older community framing treated her as Laevatain’s standard support because Ardelia was less well understood. Current sustained-DPS calcs put Ardelia clearly ahead because her amp matches the combustion damage profile while Gilberta’s inflictions interfere with burn pacing. In short-burst Laevatain content the gap closes, but most Laev play is sustained.

Should I pull Gilberta’s signature weapon?

No. Under 2% over Stanza of Memorials at full investment, under 5% over P1 Stanza. The lowest signature-vs-alternative gap on any current 6★. Stanza P4+ is the play.

Perlica or Gilberta for Yvonne?

A wash in calcs. Pick Gilberta if you need AoE pull, Alesh SP routing, or if she is already invested for another team. Pick Perlica if neither of those applies and you have her at higher investment.

Is Gilberta worth pulling if I don’t have a carry yet?

Probably not. She is a multiplier; she needs a carry to amplify. Pull a DPS first (Rossi, Yvonne, or whoever you actually want to play), then come back for her on a rerun.

Does she work in the Fest of Brilliance Laevatain comp?

She works, but Ardelia is better there. If you are pulling on Fest of Brilliance specifically to pair Gilberta with Laevatain, the math suggests pairing her with Rossi or Awyvenna on your existing roster instead.

Why does Zhuang Fangyi rate Low when Gilberta is “universal”?

Two reasons: Gilberta only buffs one Battle Skill per cycle and Fangyi’s rotation wants multi-BS support, and Corrosion overwrites part of Fangyi’s electrification vulnerability stack (which is the higher-multiplier infliction on her specifically). The damage column shrinks.

What’s the cheapest functional Gilberta build?

Stanza of Memorials at P1-P2 plus mid-tier Arts amp gear. Her signature is skippable, her gear scaling is forgiving, and the Stanza buff is what carries the team-amp role. A budget Gilberta is a real Gilberta.

Will Gilberta be obsolete after V1.3?

Almost certainly not. Her role is structural rather than tied to a specific element or damage type, and every leaked future arts DPS overlaps with her buff profile. The risk is account-side, not kit-side: she becomes redundant only if you do not own a carry she can amplify.

Where do I read more on Gilberta team comps?

The Rossi nuke build is the deepest Gilberta-team breakdown on the site, and the pull-decision post covers the banner-side question if you are mid-decision. Keep an eye on V1.3 previews for the Camille kit, which will likely add a fourth Very High synergy to this list.
