Gilberta

endgame support

supportdebufferteam_bufferflex

Gilberta earns the top tier because she fits into nearly any composition, either as a dedicated Arts enabler or as a generic flex slot. She brings the strongest Arts Susceptibility numbers currently available, and her kit also spreads Nature Infliction for Corrosion plus Vulnerable stacks, so hybrid squads benefit from her too. Her talents add team healing and extra Ultimate generation on top of the debuffs.

This endgame setup turns Gilberta into a pure enabler rather than a damage source. Delivery Guaranteed supplies Ultimate Gain Efficiency while also granting the squad an Arts damage buff, and the Eternal Xiranite pieces stack further Ultimate Gain Efficiency and Intellect so her gravity field returns faster and her Late Reply healing scales higher. Completing the set adds a flat teamwide damage increase whenever she lands an Amplify, Protected, Susceptibility, or Weakened effect, which her Ultimate does automatically. Redeemer Seal rounds out the kit with strong Intellect and Ultimate Gain rolls.

Insights

Core Mechanics

Nature Infliction comes from both her Battle Skill and Ultimate, which enables Corrosion and opens reaction windows for the rest of the squad.
Her Ultimate drops an Anomalous Gravity Field that slows everything inside and applies Arts Susceptibility, with the value growing for each Vulnerability stack already on the target.
Targets that get Lifted inside the gravity field stay airborne for the field's full duration, extending the follow-up damage window.
Her Combo Skill only becomes usable after an Arts Reaction lands on an enemy, which makes her dependent on a reaction partner.
Messenger's Song passively feeds Ultimate Gain Efficiency to allied guards, casters, and supporters, accelerating the whole team's cycles.

Scaling

Investment into Ultimate Gain Efficiency pays off the most, since it directly shortens the gap between her Susceptibility applications.
Her own damage stays low at every stage, so her Battle Skill and Combo Skill can sit at minimal investment without hurting her support output.
Intellect scales directly into her Late Reply healing, so attribute investment converts into team survivability.
She is effective from early game onward, but the size of her debuff multipliers is what makes her shine late.

Team Role

Gilberta occupies the support slot and operates from the back, amplifying the main DPS from a distance rather than trading hits. Her usual pattern is to pull enemies into a cluster with the Battle Skill, detonate it for Nature Infliction, then wait for an Arts Reaction so her Combo Skill becomes available and can Lift targets while adding Vulnerability stacks. The Ultimate anchors the kit: it drops a slowing anomaly field that applies the largest Arts Susceptibility debuff in the game, multiplying whatever the Arts or hybrid teammate does inside it. Because both her Infliction and her debuffs are self-contained, she slots into almost any squad as a flex pick, but she produces the most value next to carries that can dump burst damage during the Susceptibility window.

Explanation

Delivery Guaranteed is the pick because it bundles Ultimate Gain Efficiency with a teamwide Arts damage buff, which lines up exactly with her enabler role.

Eternal Xiranite is used since most of its pieces roll Ultimate Gain Efficiency and Intellect, speeding up her Ultimate and strengthening her healing talent.

The four-piece bonus hands the rest of the team extra damage whenever she applies Amplify, Protected, Susceptibility, or Weakened, and her Ultimate triggers it for free.

Redeemer Seal fills the second kit slot for its high Intellect and Ultimate Gain values.

Swapping to Stanza of Memorials is the option when a teamwide Attack buff or a cheaper investment is preferred.

Notes

Ultimate Gain Efficiency is the headline statistic; Intellect follows because it raises her Late Reply healing.
The set's teamwide damage bonus triggers by itself when her Ultimate applies Arts Susceptibility.
Keep Stanza of Memorials on hand for hybrid or non-Arts squads where a flat Attack buff helps more.
