INFLICTIONS & REACTIONS

Combat in Arknights: Endfield is not really about who deals the most damage on a paper sheet. The teams that clear endgame content are built around a smaller question — which of your operators bend the damage rules in your team's favour. Some amplify a specific element so every other hit lands harder. Some shave a piece off an enemy's resistance bar so the rest of the squad finally feels like it is fighting a normal target. Some build stacks that take a flat damage profile and turn it into a peaking one. This guide ranks who does which.

The reference data comes from the in-game CharacterTable, PotentialTalentEffectTable, and SkillPatchTable — the same blackboards the game itself reads to decide whether your hit gets a multiplier. We surface three signals per operator: which elements their passive talents amplify, whether any of their talents carry an ignore-resistance tag, and what element-specific effects fire on their skills. Together they cover most of what makes a kit feel "strong against this boss" or "weak into this matchup".

If you are coming from the Skill Point Generators ranking, treat this page as the other half of the same conversation. That ranking measures how fast each operator can press their buttons; this one measures what each button is worth when it lands. The two pages together explain why a slow-cycling DPS with a Heat-pierce talent can still out-clear a faster-cycling one with no element synergy at all. For the build-specific side — gear sets, weapon affixes, rotation routing — work from per-character pages such as Laevatain or Yvonne.

One scope note before the rankings. Everything below is drawn from talent and skill data only. Equipment scalars (the Aethertech set, weapon affixes), team-buff carry-over, and engine-level on-hit triggers do not show up in those tables and are out of scope here. Operators who feel strong but do not appear with tags in the matrix tables are not weak — their power simply comes from sources this page cannot see. The combat fundamentals guide covers the engine-level pieces that sit underneath every kit.

Quick Answer

Two operators carry partial resist-pierce on their kits: Laevatain shaves Heat resistance by up to roughly eighty percent at full talent ramp (ten to twenty percent per stack, four stacks maximum), and Zhuang Fangyi shaves fifteen percent Electric resistance once you have unlocked Potential 5. They are the canonical element-DPS picks for Heat and Electric specifically because resist pierce is rare and deliberately tuned.

Beyond those two, the meta-defining synergy operators are Yvonne (Cryo specialist plus status amplifier, +20% application rate and +40% effect strength), Rossi (Pyro amplifier through Razor Clawmark stacks), Estella (Cryo crit modifier), Last Rite (Cryo susceptibility applier), and Pogranichnik (Physical buff plus a three-deep self-stack ceiling). Akekuri, Chen Qianyu, and Laevatain are the deepest stack builders in the roster. Gilberta and Tangtang carry the strongest skill-tagged universal Vulnerability shred — a debuff that amplifies every element on your team equally.

Why Element Synergy Matters in Endfield Combat

Endfield's damage formula multiplies a long chain of modifiers — base attack, skill multiplier, element advantage, resistance, vulnerability, status susceptibility, crit damage. A single ignored resist or applied susceptibility can swing the final number by twenty to forty percent before any of your gear gets to do its job. That is why a team built around one strong specialist and a single softener can out-clear a team of four raw DPS units that share no synergy at all.

The rankings on this page cluster operators into five distinct roles, layered on top of their basic damage profile. Element specialists actively scale one element through their kit, either by buffing it on themselves and allies or by applying a susceptibility debuff on the enemy. Resist piercers carry an ignore-resistance tag — partial in every current case, but enough to make resist-tanky bosses tractable. Stack builders ramp from a low baseline into a much higher peak, gated by a stack ceiling that drops the moment they leave the field. Status specialists amplify how often and how hard status effects land. Universal softeners apply Vulnerability through their skills, which scales every element on your team equally.

Most operators in the roster will not have any of these tags. That is not a flaw — it just means their value comes from raw damage stats, gear scaling, or kit features that this page cannot read. The handful who do carry a tag are the ones who change how the rest of your team's damage lands, which is why they tend to anchor team compositions even when their personal numbers look unremarkable.

Element Specialists — The Element Scalers

Element specialists lean their entire kit into one element. Some buff that element on themselves and allies through passive talents; some apply a susceptibility debuff on the enemy that scales the team's damage in that element. Both directions arrive at the same outcome — get the condition triggered, and every hit in that element peaks. The buff is never free; it depends on the operator landing their condition first. Once the condition is up, the rest of the team rides the multiplier for as long as the operator stays on field.

On the Cryo side, Yvonne is the cleanest case. Her kit converts ally Cryo or Nature Infliction into Solidification and stacks a Cryo DMG-taken debuff on the target. Last Rite works from the same angle through Cryo Susceptibility, scaling with the Arts Infliction stacks her rotation consumes — her ultimate amplifies it further. Estella shaves her combo cooldown on Cryo or Nature application and grants bonus Crit DMG against Cryo-afflicted targets, doubled when Solidification is up. Three operators, three different angles into the same element, and they stack with each other rather than overlap.

On the Pyro side the cast is smaller but the multipliers are larger per source. Rossi stacks Razor Clawmark on targets, applying both Heat DMG-taken and Physical DMG-taken; crit hits on a clawmarked target trigger an extra Heat strike that scales further when Combustion is up. Laevatain applies Heat Infliction on the third stage of her basic-attack combo during her ultimate. Both want a partner who keeps the Heat condition active — a status amp like Yvonne actually transfers cleanly into a Pyro composition for that reason, because the +20% status application is element-agnostic.

The practical takeaway for team-building is that one specialist is usually enough if the rest of the team can keep their condition triggered. Pairing two specialists in the same element is rarely worth the team slot unless they amplify each other directly (Yvonne plus a Cryo carry, for instance). Pairing one specialist with a universal Vulnerability source is almost always a damage gain because Vulnerability multiplies on top of the element buff rather than competing with it.

Resist Piercers — The Rule Shavers

Most Endfield enemies carry elemental resistances that quietly chew a chunk off your damage. Late-game bosses stack those resists deliberately, which is why a team that cleared mid-game content can suddenly feel anaemic against an Aegir-tier fight. Two operators currently carry an ignore-resistance mechanic in their talent data — neither is a true one-hundred-percent bypass, but they get close enough to make resist-tanky matchups tractable.

Laevatain is the more impactful of the two. Her talent shaves Heat resistance by ten to twenty percent per stack (the per-stack value scales with talent rank from one through three), up to a four-stack maximum. At full talent rank that is roughly eighty percent of an enemy's Heat resist gone while she is on the field — close enough to a true pierce that she is the default Heat DPS pick against any boss with stacked Heat resist. The catch is that the effect is on her kit specifically, so it disappears the moment she rotates out. Heat teams plan rotations around keeping her field time long.

Zhuang Fangyi does the same job for Electric, with two important asterisks. The pierce is a flat fifteen percent rather than a stacking ramp, and it is gated behind Potential 5 — meaning it is a dupe-locked effect rather than a baseline kit feature. He still works as an Electric DPS at lower potential through his other talents, but the pierce that defines him in meta tier lists only kicks in once you have invested heavily in dupes. The same trade-off applies to any potential-gated effect on this page; it is real value, but it is not free.

Stack Builders — The Snowballers

Stack builders start a fight at a low baseline and ramp into a much higher peak. The stack ceiling is the cap on that ramp, and drop one stack mid-fight and you drop a tier of damage. Their kits are designed around field time — rotate them out before they finish ramping and you are fighting at half of what they are capable of. Sorted by ceiling depth, the current roster's stack builders look like this:

The two clean profiles in that list are Akekuri and Chen Qianyu, both of whom stack on the enemy at a five-deep ceiling from their baseline talent. That means no potential investment is required to hit their full ramp, and the stacks live on the target rather than on the operator, so partner switches do not reset them. Laevatain stacks combo stages instead, which is why her resist-pierce talent is paired with a stack ramp — she is doing two jobs at once on the same kit.

Pogranichnik is the unusual entry. His three-deep ceiling tracks on himself or on a buff he owns rather than on the enemy. Combined with his Physical-element talent buff, that points at his Vulnerability application loop — he stacks Vulnerability on enemies and on his own buff to amplify Physical damage. The ceiling tells you the cap; the rotation guide explains how to ramp to it. Yellow-tagged ceilings in the table are potential-locked, so they only kick in once you have pulled enough dupes to clear that potential level.

Status Specialists & Universal Softeners

Two smaller categories round out the synergy roles. Status specialists exist specifically to make status effects — freezing, burning, vulnerability — hit harder and land more often. Yvonne is the only canonical status specialist in the current roster: her talent boosts how often statuses apply by +20% and how hard they hit by +40%. Paired with a Cryo carry the freeze uptime difference is night-and-day, but the buff is element-agnostic, so she also plugs cleanly into Pyro or Electric teams where status application is the bottleneck.

Universal softeners apply Vulnerability through their skills directly. Vulnerability is the most powerful debuff in the game's damage formula because it amplifies hits from every element equally — the closest thing Endfield has to a free damage button. Gilberta carries the strongest skill-tagged Vulnerability shred currently in the data, with Tangtang as the secondary source. Both are worth slotting whenever your matchup is element-resistant and your primary DPS does not already carry a softener of their own.

A small handful of operators also pierce a specific element's resistance from their skills rather than from their passives. Avywenna shreds Electric resist on every cycle, and Lifeng carries a small but tagged Physical resist shred. These are less impactful than Laevatain's or Zhuang Fangyi's talent-based pierces, but they fire on every skill cast rather than waiting for a passive condition to trigger, which can matter in short fights where the passive never ramps.

Full Operator Rundown

Every operator in the current roster sorted alphabetically, with their tagged element synergy, stack-and-status mechanics, and skill effects on one screen. Empty cells mean the operator has no tagged data in that category — not that they are weak, just that the synergy is implicit and shows up in their build guide rather than in the tables this page reads.

Yellow text in the Element Synergy column flags the two full resist-pierce operators — Laevatain and Zhuang Fangyi — because those are the strongest amps in the game and you should treat them as separate tier from a normal element amplifier. Rows rendered with faded text are operators with no tagged synergy data; their value lives in raw stats, gear scaling, or kit features beyond what the talent and skill tables expose.

Element Specialists & Resist Piercers Matrix

Operators whose passive talents touch a specific element, laid out across all six elements at once. A checkmark in a cell means the operator amplifies that element through a talent. A PIERCES badge means their kit carries a resistance-ignore mechanic for that element — partial in practice (Laevatain up to roughly eighty percent of Heat resist at max talent; Zhuang Fangyi fifteen percent of Electric at Potential 5 and above).

Reading the matrix across a row tells you what an operator does to your damage; reading down a column tells you the bench depth for an element you have already committed to. Cryo is the deepest column in the current roster, which is part of why Cryo teams have been the easiest meta archetype to assemble for the last two patches. Heat is shallower but compensates with Laevatain's pierce; Electric is shallower still and leans almost entirely on Zhuang Fangyi at high potential.

Stack & Status Reference Table

Operators with stacking mechanics or status amplifiers in their passive talents, broken out per mechanic so you can see exactly what each operator contributes. The same operator can appear in multiple rows when their kit carries more than one tagged mechanic — Yvonne, for example, shows up under both Status application (+20%) and Status power (+40%).

Stack ceilings tell you the cap on a snowballing kit; status application and status power values tell you how much an amplifier multiplies an existing effect. The two readings are different mental models — one is about your operator's own damage curve, the other is about how much your operator multiplies everyone else. Both matter when you assemble a team, but they trade off cleanly: a Cryo team built around a status amplifier wants high-ceiling carries; a Pyro team built around a piercer wants reliable on-field amplifiers.

Skill-Driven Element Effects

Most of Endfield's element synergy lives in passive talents rather than in the skills themselves. A few operators are the exception — their skills carry explicit element-tagged blackboards that fire on every cast rather than waiting for a passive condition to trigger. That on-cast timing is what makes them disproportionately useful in short fights where a passive never gets enough field time to ramp.

The current data flags Avywenna, Gilberta, and Last Rite as the standout cases on the element-specific side, each with a per-cycle damage buff or resist shred that fires every time they complete a rotation. Lifeng also carries a small but tagged Physical resist shred on her skill cycle. The values are visible per operator in the full rundown table above under the Skill Effects column.

On the universal side, skill-tagged Vulnerability shred is the strongest cross-element amp in the game. Gilberta carries the highest tagged value in the current data, with Tangtang as a secondary source. Vulnerability applies to every element equally rather than to a specific one, which is why these two slot cleanly into any team archetype regardless of the primary DPS element. For operators not on this skill-tagged shortlist, the element synergy is implicit and shows up through their passive talent unlocks rather than through their skill data.

How These Rankings Are Built

For every operator the page scans three signals out of the game's published data tables. The first signal is element buffs from passive talents — the strongest element bonus on any of the operator's potential unlocks, drawn from the PotentialTalentEffectTable. The second is resist piercing, meaning any talent that carries an ignore-resistance tag; the actual percentage varies (see the Resist Piercers section for specifics, since the boolean flag does not capture how much resist is actually shaved). The third is skill-tagged element effects, summed across one full skill cycle from the SkillPatchTable, with universal Vulnerability shred broken out separately because it amplifies every element equally rather than scaling one.

The internal element names in the raw data are Cryst, Fire, and Pulse — this page uses the in-game UI labels Cryo, Heat, and Electric so the rankings match what you see in tooltips. Buff direction (whether an effect targets self/team or the enemy) is inferred from whether the talent attaches to a skill blackboard or to a buff blackboard, because the underlying BuffTable does not expose targeting metadata directly. That inference is reliable in the common cases but can produce rare false positives at the edges.

What this page deliberately does not fold in: equipment scalars from the Aethertech set and weapon affixes, team-buff carry-over from one operator to another, and engine-level on-hit triggers that fire from kits the game data does not flag. Those depend on your specific build and rotation, and a flat per-operator ranking cannot model them honestly. Treat this page as the baseline for who has these mechanics in their kit, and check per-character build guides for how to actually use them in a rotation.

Build Priority — Who To Pull First

If you are pulling on a fresh account and trying to decide which of these synergy operators to chase first, the rough order most clears suggest is resist piercer, then your element specialist, then your stack builder, then a softener. Resist piercers scale into the hardest content because the late-game enemies they bypass are exactly the ones where the rest of the roster falls off, so Laevatain and Zhuang Fangyi earn the first slot when their banners run.

Your element specialist comes next. One specialist plus a way to keep their condition triggered unlocks an entire team archetype — Yvonne for Cryo, Rossi for Pyro, Pogranichnik for Physical. If you already pulled a piercer for that element, the specialist plays a different role; you no longer need them to be the primary damage source, only to keep their amplification condition active.

Your stack builder follows as the on-field carry. The cleanest profile is the one without a potential gate — Akekuri or Chen Qianyu at their five-deep baseline ceiling, since those stacks live on the target and do not reset when allies switch in or out. Pogranichnik's three-deep self-stack works similarly but trades depth for the self-tracking that survives partner swaps better.

Finally, slot a universal softener like Gilberta or Tangtang when your matchup is element-resistant in a way your specialist plus piercer does not already cover. Softeners are less essential when you have already invested into a piercer for the relevant element, because the piercer is doing a strictly stronger job for that element specifically. Where a softener earns its slot is off-element matchups — content where your team's primary element is the wrong call but you have no other clear-comp option, and the universal Vulnerability multiplier salvages the run.
