Building a strong team in Arknights can feel overwhelming, especially with so many operators to choose from. Some are excellent for early stages, while others shine in late-game content or event challenges like Contingency Contract. Picking the right ones makes a big difference, but without guidance, it’s easy to waste resources or miss top-performing units.
That’s why I created this updated Arknights tier list for 2025. It ranks the best operators based on current game mechanics, meta shifts, and practical usage across multiple modes. If you're wondering who to invest in for long-term progress, this guide will point you in the right direction.

S+ Tier Operators

These are the operators I always rely on, no matter the challenge. They’ve carried me through high-risk Contingency Contract, late-game Integrated Strategies, and brutal event stages. If I had to restart my account, I’d prioritize these units first.

Ch’en The Holungday (Guard)

Ch’en the Holungday is my go-to for burst-heavy stages. Her Skill 2 (Chi Xiao - Unsheath) charges fast and deals wide-area Arts damage, which is rare for a Guard. She clears waves before enemies can even touch my frontlines.
Her skill uptime is short but frequent, and that makes her reliable for repeated nukes throughout long battles. She’s not just a DPS tool; she’s a rhythm-breaker that lets me reset the tempo of any tough stage.

Eyjafjalla (Caster)

Even after all the new operators, Eyja still melts enemies faster than most. Her Skill 2 (Ignition) is perfect for short, sharp damage bursts, while Skill 3 (Volcano) covers massive AoE damage over time.
I often pair her with buffers like Sora or Warfarin to push her damage even higher. She’s also flexible, solid in both early-game farming and late-game boss fights. When I need magic damage, I bring Eyja without hesitation.

Texas The Omertosa (Vanguard)

How to Use Texas The Omertosa | Operator Showcase | Arknights

Texas the Omertosa brings more than just DP generation. Her Skill 2 (Omertosa: Bullet Symphony) gives AoE Arts damage plus crowd control through stun. This makes her useful in any map with enemy rushes or ranged threats.
She’s helped me stabilize many runs when things looked out of control. Her versatility as a hybrid Vanguard-Control unit gives her a firm spot in nearly every squad I build.

Skadi The Corrupting Heart (Supporter)

Skadi (Alter) has been a game-changer for my survival-focused squads. Her aura healingis passive and doesn’t need skills to activate. That means my frontliners stay alive even during heavy enemy pressure.
What makes her shine is her Skill 2 (Tides of Wrath) it boosts ally ATK while providing regen, which helps turn average operators into damage machines. She fits into any setup that needs sustain and offense at the same time.

Surtr (Guard)

Surtr still dominates the meta with her Skill 3 (Molten Giant). I use her as a tactical nuke, drop her in, activate her skill, and watch a boss melt in seconds. She becomes temporarily invincible during her skill, which means she gets the job done before dying or retreating.
Even after her nerfs in the CN server, she remains incredibly effective for burst strategies. When I see a tough boss on the map, Surtr is one of the first names I add to my roster.

Yato (Alter) (Vanguard)

Yato (Alter) completely flips the idea of what a Vanguard should be. She has a low DP cost but performs like a guard with high burst and incredible speed. Her Skill 2 (Shadowflow Formation) lets her deal massive damage to elites and bosses while dodging attacks.
She’s perfect for taking down high-priority enemies early or holding tricky lanes by herself. I use her when I need fast deployment, high burst, and safe retreat options.

SilverAsh (Guard)

SilverAsh remains one of the most flexible and powerful operators in the game. His Skill 3 (Truesilver Slash) gives him global range, high burst, and fast clearing potential. He also has good survivability with three-block and high stats.
I can place him anywhere, and he’ll clean up the map by himself. Whether it’s a rush map or a high-defense enemy, SilverAsh gets the job done without needing too much support.

Horn (Defender)

Horn plays like a stationary artillery platform. Her Skill 3 (Final Volley) gives long-range AoE physical damage that scales with how many ammo charges she has. She doesn’t need healing thanks to her self-sustain, which lets me free up Medics for other lanes. She’s ideal in stages where I need to hold a wide area or defend against ranged units. I use her to anchor maps and build a full defense strategy around her.

A white-haired woman with red accents and a shield, a gray-haired woman with horns and a large shield, and a blonde woman with cat ears holding a weapon
These are the operators I rely on when I need consistent performance. They might not dominate the meta like the S+ tier, but they form the core of many of my successful teams. Each one brings unique value that fits perfectly in various team comps, especially in tougher game modes like Contingency Contract, Integrated Strategies, and high-difficulty event maps.

Bagpipe (Vanguard)

Bagpipe is my favorite opener in fast-paced stages. Her talent gives bonus SP to other Vanguards at deployment, which helps skill-based Vanguards like Elysium or Myrtle trigger skills almost instantly.
That early boost makes a huge difference in DP generation and lets me set up the rest of my squad quickly. Her Skill 2 (High-Impact Assault) deals heavy physical damage in a short burst, making her one of the few Vanguards who can reliably kill early enemies on her own.

Ling (Summoner Supporter)

Ling takes effort to learn, but she’s incredibly powerful once you figure her out. Her dragons act like independent units that can be placed around the map. These summons can deal AoE damage, stall enemies, and even hold lanes by themselves when upgraded.
Her Skill 3 (Drachenheide - Territory of Divinity) allows her to merge dragons into one massive unit that hits multiple enemies with high Arts damage. She requires setup time and map awareness, but in longer stages like IS or defense missions, she can solo entire sections with no support.

Fiammetta (Sniper)

Fiammetta shines in open maps with heavy enemy traffic. She targets the highest HP enemies and deals AoE physical damage. Her Skill 3 (Dante's Flames) gives her unlimited attacks over time but at the cost of her own HP, which creates a high-risk, high-reward gameplay loop.
I’ve cleared many difficult maps by placing her behind a tank and letting her clean up waves that would otherwise overwhelm my team. She demands good positioning and a healer nearby, but when she's set up properly, her damage output is hard to beat. She’s a strong pick for crowd control and elite cleanup.

Irene (Guard)

Should You Get And Build Irene? | Operator Irene Review [Arknights]

Irene is one of the most balanced and efficient AoE Guards I’ve used. Her Skill 2 (Sanction Mode) combines AoE burst with Arts damage and crowd control through stun. She’s especially useful in enemy-dense stages where I need a quick, repeatable way to stop rushes or eliminate grouped enemies.
Her attack interval is short, and she charges quickly, so she fits well into faster-paced comps. I like using her in event maps and as a side-lane unit in IS. She isn't flashy, but her efficiency in tight spots is incredibly reliable.

Specter The Unchained (Guard)

Specter the Unchained is a self-sustaining brawler. Her invincibility window with Skill 2 (Carnival) allows her to keep fighting even when surrounded, which is perfect for solo-lane defense or boss stalling.
What makes her special is her ability to operate without needing a healer during skill uptime, and with the right module upgrades, she becomes one of the few Guards who can tank and deal damage at the same time. I use her when I need someone to hold a line alone or buy time in dangerous setups. She’s my backup plan when traditional tactics start to fail.

Goldenglow (Caster)

Goldenglow is one of my favorite Caster picks when I’m up against grouped mid-HP enemies. Her Skill 3 (Tactical Chain Lightning) launches bouncing electrical bolts that target multiple enemies randomly, but within a predictable pattern. With high SP recovery and fast uptime, she shreds enemy clusters easily.
She works best when placed near choke points or crossroads where her lightning can reach multiple targets. I like pairing her with SP boosters or buffers like Sora to keep her output high. She's especially helpful in IS where positioning flexibility matters more.

Penance (Defender)

Penance isn't just a tank she’s a retaliation machine. Her Skill 2 (Retribution) turns her into a walking spike wall, returning Arts damage every time she’s hit. This makes her perfect for stages with low-ATK, high-volume enemies.
I’ve seen her delete entire waves just by standing still. What’s more, she generates DP on kill when she’s blocking enemies, giving her economic value on top of raw defense. I bring her to CC stages where healing is restricted or damage reflection is needed. She’s one of the most versatile defenders I’ve raised.

A Tier Operators

These operators are strong, but their impact depends on the map, team comp, or strategy. I use them regularly, but I bring them in when their specific strengths match what the mission needs. They're not as universally dominant as S or S+ tier, but in the right hands, they can be game-changers.

Mudrock (Defender)

Mudrock is the definition of self-sufficiency. She doesn’t need healing from medics thanks to her shield-based passive healing and invincibility windows built into her kit. Her Skill 2 (Shield of Threads) makes her completely immune to damage for several seconds and gives her time to restore her shield.
I place her on lanes that need a solo anchor. She can stall entire enemy waves without support, which frees up my healers and buffers for other lanes. She's perfect for stages with healing bans, constant chip damage, or swarm-type enemies.

Mostima (Caster)

Mostima is often overlooked, but she still brings solid crowd control to the field. Her Skill 2 (Artesa) combines AoE Arts damage with a long-lasting slow effect, and she also provides SP regen to nearby casters, which helps teams with burst casters like Eyjafjalla or Goldenglow.
I use her in Integrated Strategies and IS#3 boss stages, where delaying enemies is more important than raw DPS. She's great when you need a slow-based comp or support your ranged lane with constant control. Not top-tier damage, but great utility and team synergy.

Lappland (Guard)

Lappland still earns a spot in my roster because of her silence effect and dual Arts/physical damage. Her Skill 2 (Wolvendict) attacks multiple enemies and triggers Arts damage on hit, which works well against enemies with high DEF but low RES.
She’s especially useful in stages with caster-type enemies, drones, or enemies that use annoying skills (like exploding or shielding units). Silence can shut those down completely. While newer units offer better damage, Lappland remains valuable in utility-heavy missions or where silence is key.

Heidi (Supporter)

Heidi brings one of the most useful passive buffs in Integrated Strategies. Her skills buff ATK, DEF, and RES in an area, and her range allows her to cover a wide portion of the map. I use her as a passive core unit in IS runs, especially when I need to scale my team early without relying on traditional buffers.
Her Skill 2 (Command: Coordination) is the highlight it gives teamwide buffs over a large radius and makes early squads more resilient. She fits into nearly any setup and helps under-leveled or off-meta units perform better. Not flashy, but strategic.

Amiya (Guard - Alter)

Amiya’s Guard form is surprisingly powerful in boss fights. Her Skill 3 (Courageous Moment) gives her massive burst potential, converting her damage to True damage, which ignores both DEF and RES. It’s perfect against high-defense bosses like Patriot or Mudrock in Challenge stages.
She’s not good for long maps or swarm waves due to her self-stun after skill use, but I treat her as a one-skill nuke when I need to bring down a priority target fast. With the right timing and support (especially cooldown reduction or regen), she becomes a reliable boss killer.

B Tier Operators

These operators helped me a lot in the early game, but they struggle to keep up in high-difficulty content like Contingency Contract, high-risk IS, or advanced event stages. They still serve a purpose if you're just starting out or looking to build meme teams, but I wouldn’t invest heavily in them unless you already have extra resources.

Kroos The Keen Glint (Sniper)

Kroos the Keen Glint: A MAJOR Upgrade, or A DISAPPOINTMENT? | Arknights Operator Spotlight

Kroos was one of my first maxed-out snipers. She’s easy to obtain, low on cost, and simple to use. Her Skill 2 gives her extra hits and a faster attack rate, which helps clear out light enemies fast.
In the early game, she performs well because of her cheap deployment cost and fast upgrades, but once you unlock 5 or 6 snipers, she gets outclassed in both damage and utility. Still, she’s a great starter option and works well in early Integrated Strategies due to her quick deployment and low investment.

Melantha (Guard)

Melantha is one of the most efficient single-target melee units for beginners. Her high base ATK and low DP cost make her a powerful option for clearing early maps with assassinations or burst melee damage.
I used her a lot when I didn’t have access to high-rarity Guards. She’s perfect for eliminating high-priority threats quickly, especially in narrow lanes where you don’t need AoE. That said, she lacks survivability, utility, and synergy with buffs, which limits her use in mid to late-game stages.

Frostleaf (Guard)

Frostleaf brings built-in slow effects and a ranged melee attack, which is useful for early control comps. She can attack enemies from a distance, slowing them down while dealing physical damage. That kind of control helps in maps with drones or fast-moving units.
But the problem I ran into is her low stats and low skill uptime. Her damage falls off quickly in harder stages, and there are better options like Manticore or Gladiia that fill the same role but with higher scaling and better synergy. Still, she can help you manage swarm stages early on.

Lancet-2 (Medic Robot)

Lancet-2 is surprisingly helpful in Integrated Strategies, side modes, and challenge runs. She costs zero deployment points and automatically heals nearby allies, which gives you breathing room in maps where DP is tight or medics are banned.
I often deploy her early to support a solo Defender or Guard while I build up deployment points for stronger operators. She can’t replace a real Medic, and her healing is weak, but in the right situation, she helps keep runs alive. Good for memes, better than expected for early IS runs.

Best Operators By Role

Vanguard

  • Texas the Omertosa: She’s a powerhouse in modern content. Her stun utility shuts down early rushes, and her Skill 2 brings massive burst damage on top of standard DP generation. She works in nearly every map where control matters.
  • Bagpipe:Bagpipe still dominates as a DP generator and lane opener. Her talent boosts initial SP for vanguards, letting Skill 1 users like Myrtle or Elysium start faster. Plus, she deals real damage and survives longer than most vanguards.
  • Yato (Alter):Yato Alter is cheap to deploy and hits like a truck. Her low DP cost and boss-busting burst damage make her perfect for maps that need quick deploy/redeploy cycles.

Guard

A three distinct characters of arknights, one with horns, another with a bird, and the third with a weapon.
  • Surtr:Surtr still deletes bosses. Skill 3 melts everything on the map, and the self-retreat buys you time and resets fast. Even with some power creep, nothing replaces her delete button.
  • Ch’en the Holungday: Her Skill 2 spam clears waves like clockwork. She shines in most events where mob control and elite kill pressure are both needed. She’s also flexible in Integrated Strategies thanks to quick rotation.
  • SilverAsh:Truesilver Slash is still broken in the right hands. With three block, global range, and an explosive skill window, he’s a core pick in many auto-deploys and tight clears.

Sniper

  • Fiammetta:She’s a high-risk, high-reward AoE sniper that thrives in open maps. Skill 2 rains explosive bolts in a wide area, and when set up right, she controls lanes better than almost anyone else.
  • Ashlock: Ashlock’s cannon-style sniping covers tightly packed enemy waves. Her defensive trait lets her stay up longer, and Skill 2 provides a powerful stun that stops rushes dead.
  • Exusiai:Exusiai is still viable, but she’s been powercrept by snipers like Fiammetta and Rosa. Her single-target burst is great for drones and light mobs, but she needs team support to stay relevant in top-tier maps.

Caster

  • Eyjafjalla:Eyja’s Skill 2 and Skill 3 are still top-tier. S2 melts heavy targets with short cooldowns, and S3 provides a massive burst for grouped enemies. She also scales well with SP batteries and buffs.
  • Goldenglow:Goldenglow’s electric chain mechanic deals solid AoE damage with high uptime. She fits well into caster-heavy comps and works great when you need to delete swarms quickly.
  • Dusk:Dusk is great in turtle comps and maps with predictable spawn paths. Her Ink Spirits add map-wide pressure, and Skill 3 turns her into a caster-version of a wave clearer. She’s tricky to master but worth it.

Medic

  • Kal’tsit:Kal’tsit isn’t a traditional healer. Mon3tr is the real starhigh HP, great DPS, and free blocking. She offers healing plus an off-tank, which is rare. In IS or challenge modes, she’s often an MVP.
  • Shining:Shining focuses on physical defense, and her buffs are best used in defender-heavy comps. When I’m facing high ATK enemies, she keeps my frontlines alive longer than most Medics.
  • Nightingale:Nightingale is still the queen of Arts resist and AoE healing. Her deployable cages reduce Arts damage and keep squishy units from getting nuked. Essential for high-Arts pressure maps.

Defender

  • Horn:Horn is a ranged Defender with artillery capabilities. She’s best when set up early to handle lane control from a safe distance. Skill 2 and 3 both offer serious firepower.
  • Penance:Penance’s counter-damage and AoE retaliation make her perfect for tank-focused comps. She shines in stages where enemies group up or hit hard, turning their damage back on them.
  • Mudrock:Mudrock works without Medics. Her barrier system and self-sustain let her solo lanes and survive longer than most Defenders. I bring her when I want a lane held without babying the tank.

Supporter

  • Skadi the Corrupting Heart (Alter):She’s my go-to for team sustain and buffs. Her healing, damage reduction, and resistance boost make her a complete support package. Great in IS and boss fights.
  • Ling:Ling’s summons can solo entire lanes or even maps, but she takes practice. Once you understand how to rotate her dragons properly, she becomes one of the most powerful IS units available.
  • Suzuran:Suzuran provides massive slows, healing, and a support buff field. Her Skill 3 is perfect for boss control or stalling fast elites. I use her often in crowd control heavy teams.

Specialist

  • Weedy:Weedy is still the push queen, especially in environmental stages. Her Skill 3 yeets enemies off ledges with style. I use her for cheese clears or maps with death pits.
  • Phantom: Phantom’s instant redeploy, clone, and silence make him valuable in technical maps. He’s great for interrupting casters, assassinating snipers, or blocking drones. Reliable and fast.
  • Gladiia: Gladiia excels in CC stages and maps with water mechanics. Her drag + bind combo and skill cycle make her useful in stalling or disrupting elite waves. She also pairs well with push or pull comps.

How Events And CC Shift The Meta

Whenever a major event drops especially Contingency Contract (CC) or a new Integrated Strategies season it changes how I evaluate my operators. I don’t stick to a static tier list. I adjust based on what the game throws at me.

Contingency Contract (CC) Forces Hard Re-Evaluation

CC punishes poor positioning, weak utility, and low survivability. Every time I go into a high-risk CC, I focus on three things:
  • Global Range Skills:Operators like SilverAsh or Horn dominate here. If I can clear enemies before they even reach my line, that’s already a win.
  • Tankiness and Self-Sustain:Mudrock and Penance carry hard. I don’t have time to babysit units when enemies are buffed to absurd levels.
  • Burst AoE and Control:Ch’en Holungday’s quick rotations or Suzuran’s global slow completely change how tight CC runs feel. Survival isn't enough; I need complete wave control.
CC always reshapes which operators feel essential. It also exposes which ones just can’t keep up under pressure.

Integrated Strategies (IS) Prioritizes Synergy

In IS, isolated performance matters less. It’s about how well an operator fits into a team comp over multiple random stages. I look for:
  • Consistency:Operators like Ling, Texas the Omertosa, and Skadi Alter are strong across most floor types.
  • Versatility:I favor operators that work in multiple roles or team archetypes. If I draft Goldenglow, I know she’ll perform in both swarm and boss maps.
  • Self-Sufficiency:Mon3tr from Kal’tsit, or Phantom with his clone, can solve problems without draining team resources.
IS rewards operators who bring long-term value not just high damage.

Limited Banners Bring Power Shifts

Some banners completely break the meta. When I pulled Skadi Alter or Ch’en Holungday, they immediately changed how I cleared content. These kits are often overloaded:
  • Multiple roles packed into one unit
  • Built-in sustain, buffs, and flexible damage types
  • High uptime with little support needed
Every limited operator since Surtr has made me re-rank parts of my list. These units shift the baseline of what “S-Tier” really means.

Why I Always Adjust My Tier List After Major Events

Each new event forces me to face different map designs, enemy types, and risk mechanics. I always go back to my list, figure out who carried, who fell short, and who became dead weight. That process keeps me ready for:
  • The next IS run
  • High-risk CC week
  • Time-limited events with weird modifiers
