MASTER THE FRONTIER: THE ULTIMATE SQUAD BUILDING GUIDE FOR ARKNIGHTS: ENDFIELD
Table of Contents
Welcome, Endministrators. Whether you’re pushing through the rusted ruins of the Broken Lands or facing down massive Aggeloi in the Umbral Monument, your success on Talos-II depends on more than just high-rarity operators. It’s about Tactical Synthesis — building a four-person squad where every skill and element clicks into place.
The introduction of the Umbral Monument signifies a definitive shift in Arknights: Endfield’s endgame architecture. Moving beyond the industrial management of the Automated Industry Center, it represents a high-fidelity tactical combat gauntlet. As a permanent and resettable endgame feature, the Umbral Monument serves as the primary metric for account progression and tactical mastery, offering a total of up to 2,400 Oroberyls across its various stages and associated “Monumental Etching” events.
In this guide, we’re breaking down the meta-defining team compositions for every combat scenario you’ll face, including the ultimate test of skill: the Umbral Monument.
TL;DR - Key Points
- Tactical Synthesis over rarity — Success depends on managing Skill Points (SP) and the Stagger Meter, not just pulling 6-stars
- Combat Loop mastery — Aggressive Recovery via Final Strikes + Finishers on staggered enemies creates your “Nuke Window”
- Overworld meta: “Vortex & Burn” — Gilberta group + Laevatain nuke for instant mob deletion with Combustion chain reactions
- Elite boss meta: “Cryo-Shatter” — Stack Cryo, fill Stagger, shred resistances with Corrosion, then execute with Shatter reactions
- Agony Mode survival — Sustain is king; Ardelia + Tangtang Time Stop are S-Tier for poison fog and mob swarms
- F2P physical teams remain viable — Endministrator + Chen Qianyu vulnerability stacking with Pogranichnik SP battery
- Umbral Monument rewards — 2,400 Oroberyl total, Marks of Perseverance, 24,000 T-Creds, and rare materials on first clear
- Equipment meta shifts — Swordmancer for Physical, Xiranflow for Electric reaction consumption, Frontiers for SP-heavy teams

The Foundation: Understanding the Combat Loop
Before diving into specific teams, every successful squad relies on managing two resources: Skill Points (SP) and the Stagger Meter.
Aggressive Recovery: You regain SP primarily through “Final Strikes” (the end of an attack chain) and “Finishers” performed on staggered enemies. This means your rotation should always flow from basic attacks → combo skills → finishers to maximize SP generation.
The Stagger Window: Filling an enemy’s Stagger bar dazes them and grants your squad a massive damage multiplier. This is your “Nuke Window.” Every team composition should be designed around reaching the Stagger state as quickly as possible and capitalizing on the damage amplification window that follows.
Understanding this loop is what separates competent players from elite ones. High-rarity operators with no SP to use their skills are worthless. Teams that chain SP recovery into stagger into burst damage clear content effortlessly.

Scenario 1: Overworld & Mob Clearing (The “Speed-Clear” Meta)
In the overworld, you want frontloaded damage and crowd control. You don’t have time for long setups; you want to group enemies and delete them instantly.
The “Vortex & Burn” Team
| Role | Operator | Function |
|---|---|---|
| Core (Supporter) | Gilberta | Gravity pull groups enemies into single point |
| Core (Striker) | Laevatain | Melting Flame / Ultimate detonates grouped targets |
| Support (Vanguard) | Wulfgard or Akekuri | Heat Infliction enables Combustion reactions |
| Sustain | Ardelia or Estella | Healer keeps squad healthy during aggro pulls |
Tactical Rotation:
- Initiate with Gilberta’s Gravity Mode to pull all enemies into a single point
- Follow up with Wulfgard or Akekuri to apply Heat Infliction
- Switch to Laevatain and unleash her Melting Flame or Ultimate
- Because enemies are grouped, the resulting Combustion reactions overlap, creating an explosive chain reaction that deletes entire mobs instantly
This composition excels in world exploration, resource farming, and any content where mob density is high. The key is maintaining this rotation loop to ensure Laevatain’s Ultimate is always available when you encounter new enemy groups.
Full Ultimate Generation Team
For sustained overworld clearing where you face multiple encounters in succession, the “Full Ultimate Generation Team” ensures every operator reaches their Ultimate in a single rotation:
Laevatain + Ardelia + Wulfgard + Akekuri
This composition is highly recommended for Umbral content as well, since characters start stages with zero energy. The four-Heat operator synergy guarantees that Laevatain can reach her Ultimate in a single rotation, which is vital for clearing time-sensitive content.
Scenario 2: Elite & World Bosses (The “Single-Target Nuke”)
Bosses have massive health pools and punishing mechanics. To win here, you need to “flood” the boss with elemental stacks and detonate them during the Stagger window.
The “Cryo-Shatter” Executioners
| Role | Operator | Function |
|---|---|---|
| Core (Striker) | Last Rite | Massive single-target burst, Winter’s Devourer Ultimate |
| Core (Caster/DPS) | Yvonne | Boss-killing benchmark, stacks Crit during freeze windows |
| Enabler (Supporter) | Xaihi | Rapid Cryo Infliction application, high-range safety |
| Utility | Ardelia | Corrosion application shreds all enemy resistances |
Tactical Rotation:
Phase 1 (Setup): Use Xaihi and Yvonne to rapidly build 3+ stacks of Cryo Infliction. Xaihi’s range keeps you safe while Yvonne’s kit excels at stacking Critical Rate and Damage during freeze windows.
Phase 2 (Stagger): Use heavy attacks to fill the boss’s Stagger meter. Time your highest-impact skills to coincide with the Stagger window for maximum damage amplification.
Phase 3 (The Nuke): Once the boss is Solidified (frozen), Ardelia applies Corrosion to shred all resistances. This is the critical setup step that transforms good damage into catastrophic damage.
Phase 4 (Execution): Last Rite uses her Ultimate, Winter’s Devourer. This triggers a Shatter reaction, converting the freeze state into a catastrophic burst of Physical damage that can delete 30-40% of a boss’s HP in a single rotation.
The Cryo Loop Alternative
For players who prefer sustained DPS over burst, the Yvonne-centric Cryo Loop is the benchmark for boss-killing. Yvonne utilizes her Ultimate to stack Critical Rate and Damage during freeze windows, providing consistent high DPS throughout the encounter rather than relying on a single execution window.
Scenario 3: The Ultimate Test — Umbral Monument (Agony Mode)
The Umbral Monument is the current peak of endgame content. The gameplay experience is bifurcated into Normal and Agony modes:
- Normal Mode (Lv.60 enemy cap): Diagnostic environment for team synergy. Items allowed. Your playground.
- Agony Mode (Lv.90 enemy cap): Extreme modifiers including enhanced enemy speed, disabled healing tacticals, and removal of Perfect Dodge mechanics in specific stages. No items. Zero room for error.
The “Agony Survivalist” Team
| Role | Operator | Function |
|---|---|---|
| Core | Laevatain (Heat Striker) or Zhuang Fangyi (Electric Hypercarry) | Primary damage output |
| Sub-DPS/Utility | Tangtang | Cryo Sub-DPS with full-screen Time Stop Ultimate |
| Universal Healer | Ardelia | Consistent healing counters Agony’s resource restrictions |
| Tank/Secondary Sustain | Ember (Defender) or Snowshine (Defender) | Damage reduction, parry mechanics, shield support |
Stage-Specific Team Deployment Meta
While elemental archetypes provide a baseline, specific stage mechanics — especially in Agony mode — often dictate the “best-in-slot” composition to ensure a Trimmed Medal clear.
Inorganic Construct Series
| Stage | Best Team Composition | Primary Tactical Advantage |
|---|---|---|
| Rock Solid | Endministrator, Chen Qianyu, Pogranichnik, Ardelia | High physical burst for core reveal windows; Lift/Crush interrupts |
| Rampaging Shields | Snowshine/Catcher, Endministrator, Chen Qianyu, Ember | Tank/Parry blocks charges; CC disables shield defenses |
| Bolts and Shadows | Zhuang Fangyi, Perlica, Arclight, Gilberta | Gilberta groups crawlers; Fangyi provides rapid AoE wave clear |
Rock Solid (Agony Mode): The boss repels damage from the front and requires recognition of weak points. Preserve SP and Ultimates for the moment the boss jumps to create a shockwave. Jump over this shockwave to reveal a small HP gauge (the weak point). Successful hits instantly stagger the boss for a massive damage window. Using a high-range support like Xaihi allows safe circling while waiting for the shockwave cue.
Rampaging Shields (Agony Mode): High-mobility enemies that charge create wonky hitboxes and stun-lock risks. Catcher or Snowshine block charges and provide up to 90% damage reduction via their skills. Kill both shield enemies simultaneously — if one dies too quickly, the survivor gains CC immunity and a ramping ATK buff.
Bolts and Shadows (Agony Mode): The most mechanically dense stage. Phase 1: eliminate crawling spawns. Phase 2: ignore everything except the boss once its shield breaks to capitalize on the stagger. Rapid projectile attacks make this an ideal stage for SP generation via chained perfect dodges.
Those Forsaken by the Land Series
| Stage | Best Team Composition | Primary Tactical Advantage |
|---|---|---|
| Survive the Gas (Poison Fog) | Endministrator, Chen Qianyu, Perlica, Ardelia | Ardelia’s healing echoes across squad to offset constant DoT |
| Unorthodox Tactics (Mob Swarms) | Laevatain, Wulfgard, Akekuri, Gilberta | Premier AoE damage for mob swarms; grouping via Gilberta |
| Ballista and Axe (Dual Elites) | Yvonne, Last Rite, Xaihi, Gilberta | Cryo Solidification freezes both bosses for double shared-HP damage |
Survive the Gas (Agony Mode): Constant poison fog drains squad HP over time. Ardelia is mandatory — her Rocky Whispers and Wooly Party provide consistent healing that echoes across the squad. Since healing is echoed, dodging with the active operator is critical to minimize extra incoming damage. Prioritize staggering the Vanguard early to prevent it from providing armor scales to allies.
Unorthodox Tactics (Mob Swarms): Enemies gain massive ATK buffs the longer they stay alive. Speed is essential. Nidwyrms are priority targets — their corrosive spit creates high-damage puddles for melee units. Use Gilberta to group enemies and Laevatain to nuke them before their damage becomes “one-shot” territory.
Ballista and Axe (Agony Mode): Dual boss fight requiring high mobility and parry mechanics. The melee Executioner follows the active character while the ranged Ballista fires barrages from distance. Stay near the Ballista — the Executioner naturally walks into your AoE, allowing you to hit both and deal double damage to their shared HP pool. Operators like Snowshine or Catcher are incredibly effective for blocking high-damage telegraphed attacks from the Executioner. Save an interrupt skill for the Executioner’s grab attack.
Searing Scars Series
| Stage | Best Team Composition | Primary Tactical Advantage |
|---|---|---|
| Sea of Loathing | Yvonne, Xaihi, Gilberta, Tangtang | High-end grouping and ranged chain-breaking; avoid smoke slows |
| Melting Point of Flesh | Endministrator, Chen Qianyu, Pogranichnik, Ardelia | Physical status (Lift) interrupts flamethrowers; high stagger uptime |
| Howling Flame | Endministrator, Chen Qianyu, Pogranichnik, Estella/Tangtang | Active SP generation (Pog) and Heat stack clearing via reactions |
Sea of Loathing (Agony Mode): Cloud Stalkers spew green smoke (healing) and gray smoke (slowing/no dodge), alongside the Breaking Gust chain-hook mechanic. Kill Cloud Stalkers first to regain movement. If chains appear, they must be broken within 12 seconds to prevent a lingering stun. Gilberta is the MVP for grouping Cloud Stalkers into a central kill zone. Ranged operators like Yvonne or Fluorite make breaking anchors trivial since they don’t have to chase them down.
Melting Point of Flesh (Agony Mode): Two Bonekrusha Arsonists and exploding slugs. Perfect Dodges are disabled. Stagger the first Arsonist immediately before the second spawns (~30 seconds in) to gain a numbers advantage. Manage slugs by walking into their range and retreating to trigger them pre-emptively. Sustain-heavy teams with Ardelia and Ember are preferred since dodging is locked.
Howling Flame (Hill Smasher Boss): The boss regularly enters an Enraged state, gaining ATK and Damage Reduction based on Heat Infliction stacks. Passive SP regeneration is disabled during Enrage. The boss becomes lethal at 4 stacks. Players must consume these stacks via Arts Reactions (Electric, Cryo, or Nature Bursts) to shorten Enrage duration and prevent its special rocket jump blast. Use active SP engines like Pogranichnik. Physical teams slotting Tangtang or Estella for stack clearing are highly effective.
Key Agony Mode Strategies
Survive the Gas (Poison Fog): This stage constantly drains your HP. Because you can’t use tactical items, you must run Ardelia. Her Rocky Whispers and Wooly Party provide the consistent healing needed to counteract the stage’s poison.
The Time-Stop Cheat: Tangtang is an S-Tier pick for Agony Mode. Her Ultimate triggers a full-screen Time Stop that freezes all enemies — including bosses. This provides a safe window to heal with Ardelia or dump your burst damage without fear of retaliation.
Unorthodox Tactics (Mob Swarms): Enemies gain massive ATK buffs the longer they stay alive. Speed is essential. Use Gilberta to group the worms and Laevatain to nuke them before their damage becomes “one-shot” territory.
Ballista and Axe (Dual Elites): This dual boss fight requires high mobility and parry mechanics. Operators like Snowshine or Catcher are incredibly effective here for blocking high-damage telegraphed attacks from the Executioner while you focus down the Ballista.
Scenario 4: F2P & Early Game (The “Physical Steamroller”)
If you’re just starting, the Physical Breach system is your best friend. It’s reliable, consistent, and uses characters you get for free.
The “Unstoppable Breach” Squad
| Role | Operator | Function |
|---|---|---|
| DPS | Endministrator (Guard) | Crush consumes Vulnerability stacks for massive Physical damage |
| Sub-DPS | Chen Qianyu (Guard) | Lift and Knock Down build 4 Vulnerability stacks |
| SP Battery | Pogranichnik (Vanguard) | Active SP generation keeps rotations flowing |
| Sustain | Ember or Snowshine (Defender) | Shield and damage reduction keep the squad alive |
Tactical Rotation:
- Stack Vulnerability: Use Chen Qianyu’s Lift and Knock Down skills to build 4 “Vulnerable” stacks on the target
- The Payoff: Once at 4 stacks, the Endministrator uses a Crush skill to consume all stacks for massive Physical damage
Physical teams remain the “gold standard” fallback due to high stagger pressure. The Endministrator and Chen Qianyu form the core, building Vulnerability before detonating them with “Crush” to bypass defenses without relying on elemental chains. The Swordmancer gear set (+20% Stagger Efficiency & Stagger Follow-up Hit) is best-in-slot for both Endmin and Chen Qianyu.
Core Elemental Archetypes
The Heat Engine (Carry: Laevatain)
Heat teams revolve around the Combustion status. The Full Ultimate Generation Team (Laevatain, Ardelia, Wulfgard, Akekuri) ensures Laevatain can reach her Ultimate in a single rotation — vital since characters start stages with zero energy.
Heat excels in overworld mob clearing and sustained boss fights where Combustion DoT chips away at health pools between burst windows.
The Cryo Loop (Carry: Yvonne / Last Rite)
Cryo teams specialize in battlefield control via Solidification. Yvonne is the benchmark for boss-killing, utilizing her Ultimate to stack Critical Rate and Damage during freeze windows. Last Rite offers massive single-target burst but requires deep Cryo stacking support from Xaihi and other Cryo applicators.
The Electric Cadence (Carry: Zhuang Fangyi)
Electric teams focus on the “Empyrean of Truth” state. Zhuang Fangyi is the premier DPS for Version 1.2, relying on Perlica for initial Electrification and Arclight for SP generation to feed her high consumption. If you have Zhuang Fangyi, her damage ceiling is currently the highest in the game, making her the best choice for clearing Agony Mode timers. Just pair her with Alesh or Arclight to solve her high SP costs.
The Xiranflow gear set (Stacking DMG bonus on reaction consumption) is best-in-slot for Zhuang Fangyi, rewarding teams that invest in buildup before the burst window.
The Physical Stacking Engine (Carry: Endministrator)
Physical teams remain the “gold standard” fallback due to high stagger pressure. The Endministrator and Chen Qianyu form the core, building Vulnerability before detonating them with “Crush” to bypass defenses without relying on elemental chains. The Swordmancer set (+20% Stagger Efficiency) is essential.
Equipment Meta: Best-in-Slot Gear Sets
| Gear Set | Bonus | Best For |
|---|---|---|
| Swordmancer | +20% Stagger Efficiency & Stagger Follow-up Hit | Endministrator, Chen Qianyu |
| Xiranflow | Stacking DMG bonus on reaction consumption | Zhuang Fangyi |
| Qingbo | Combo Skill CDR & Skill DMG boost | Perlica, Arclight |
| Frontiers | Team DMG +16% for 15s after SP recovery | Pogranichnik, Arclight |
The equipment meta has shifted dramatically in Version 1.2. Where earlier gear granted bonuses for simply applying elemental inflictions, the new sets reward removing those statuses through reaction consumption. This shifts the focus from application uptime to coordination between status-applier and status-consumer, creating a rotational hierarchy where teams that reliably build Infliction stacks before the DPS triggers their highest-multiplier attacks see dramatically higher returns.
Final Strategy Pro-Tips
Rarity Isn’t Everything: For the Umbral Monument, a well-built 4-star like Akekuri is often more valuable than a random 6-star because she acts as an SP battery, keeping your healer’s skills active. Focus on role synergy over star rating.
Sustain is King: In Agony Mode, if your healer dies, the run is over. Focus on Intellect and Will attributes on your gear for your supports to maximize their healing output and damage reduction. Ember and Snowshine with 25,000+ HP are standard benchmarks for Agony clears.
The 1.2 “God Tier”: If you have Zhuang Fangyi, her damage ceiling is currently the highest in the game, making her the best choice for clearing Agony Mode timers. Just pair her with Alesh or Arclight to solve her high SP costs.
Invest Broadly, Not Deeply: Everyone needs Level 80 minimum for Agony content. Spread power means all operators need investment, unlike hypercarry comps where supports can stay low. Prioritize your main carry to Level 90 first, then bring supports to 80.
Play the Mechanics, Not the Timer: The 10-minute timer is generous. Focus on executing stage mechanics correctly rather than rushing. Most Agony failures come from mechanical errors, not insufficient DPS.
Resource Rewards: The Umbral Monument is the most consistent source of Oroberyls for endgame players. Clearing Agony stages provides permanent Marks of Perseverance and rare material drops. The first-clear bundle across all stages provides 24,000 T-Creds, 3 Advanced Cognitive Carriers, 1 Mark of Perseverance, and 8 Protohedrons.
Good luck out there, Endministrator. Talos-II doesn’t forgive mistakes, so build your squad wisely.
