Every pack purchase in Last Asylum starts with the same question: which hero is actually worth the investment? This Last Asylum tier list ranks every hero by real combat value for players spending $500+/month — from S+ premium UR picks like Shadow down to situational SSR fillers.
Last Asylum: Plague hero tier list: what actually separates heroes in this game
Most Last Asylum: Plague hero tier lists rank heroes by raw stats. This one ranks them by investment return, which is a different question. A hero's tier placement at low star ranks is not the same as their tier placement at max investment. And a well-built A-tier hero at 6-star outperforms a half-built S-tier hero at 2-star in almost every game mode.
The tier list below reflects where each hero lands at competitive investment levels, not at base rarity. The investment priority section below the tier table is what actually determines where your monthly budget should go.
Last Asylum: Plague currently has 20 heroes across four rarity tiers. UR heroes are the ceiling. SSR heroes are the competitive mid-range. SR heroes serve early game only and should be benched once any SSR or UR is available.
Last Asylum UR hero investment priority
Arthur (first investment, no exceptions)
Arthur is the mandatory first investment in Last Asylum: Plague at every spending level. He is the only UR tank available in standard summons from day one. His shards appear in the Tavern recruitment pool, the Alliance Shop, and event rewards, making him the most accessible UR hero in the game.
His kit does three things simultaneously: Strong Will reduces damage taken by all allied tanks, Rock Solid generates an HP-scaling shield on a 4.5-second cooldown, and Earthshattering deals AoE Physical damage to all enemies while reducing incoming damage for nearby allies. At 8-star he unlocks Tenacity, which boosts ATK, HP, and DEF by 20% and increases skill cooldown speed by 10%. This single threshold transforms him from strong to dominant.
Every other hero performs better behind a maxed Arthur. His frontline protection is what keeps Marlena and your damage dealers alive long enough to output damage. Invest in Arthur first before any other hero in any mode.
Marlena
Marlena is the highest burst damage dealer in Last Asylum: Plague and the core duo partner for Arthur. Her ultimate summons sword winds that target random enemies with heavy Energy damage. She scales exceptionally with star rank investment, the damage numbers becoming significantly more impactful at higher tiers.
Her shards are available through summon banners and certain event rewards. The first top-up pack in the store typically delivers Marlena shards at a very high value-per-dollar ratio, making her the recommended first direct pack purchase after the Monthly Pass.
Arthur plus Marlena is the foundation of the strongest squad in Last Asylum: Plague in every game mode. Both need to be built before investment moves to any other hero.
Shadow (premium-gated)
Shadow is the most stat-loaded hero in Last Asylum: Plague. He is the only hero whose maximum HP exceeds 1 million at full build, a Ranger-Tank hybrid that deals carry-level damage while providing team-wide Energy damage reduction.
His auto attacks fire three projectiles per cycle at 210% ATK each (630% ATK total per cycle). His ultimate deals 462% ATK AoE damage. His second ability delivers 922.5% ATK AoE while reducing enemy Energy damage by 40.2% for 5 seconds. His passive reduces Energy damage received by all allies by 22% permanently.
This passive is what makes Shadow the ideal third investment after Arthur and Marlena. Arthur's Earthshattering reduces Physical damage for allies. Shadow's passive reduces Energy damage. Together they provide full damage type coverage across the entire squad. This combination is the reason Shadow is worth the premium acquisition cost despite being the third UR hero to build rather than the first.
Shadow shards come exclusively through top-up rewards and premium purchase paths, not standard summons. For accounts investing $1,000 or more per month, this is a barrier worth planning for rather than avoiding. Full skill breakdown and build priority in the UR Heroes guide.
Harper (accessible via Daily Offer)
Harper is a UR support hero from the Warrior faction. Unlike Shadow and Cynthia, Harper is accessible without premium purchase paths, unlockable through the Daily Offer starting at server age 22 days.
His ultimate, War Melody, increases all allied heroes' ATK by 21% for 5 seconds. At 2-star the effect also increases Energy damage dealt by allies by 4.5% for 7 seconds after activation. His protective bubble skill reduces damage received by the lowest-HP ally, providing a survival layer that extends your formation's combat window during boss waves and sustained PvP engagements.
Harper's value is multiplicative. A 21% ATK buff applied to Arthur, Marlena, and Shadow simultaneously produces more total output than any single-hero investment at equivalent resource cost once the core three are built. He belongs in the fourth investment slot rather than earlier because the ATK buff scales with the power of the heroes it affects. An undeveloped Marlena receiving a 21% ATK buff produces less total value than a fully built Marlena receiving the same buff.
Cynthia
Cynthia is a carry-class Ranger whose ultimate deals heavy damage to enemies within range. She is harder to obtain than Arthur, Marlena, or Shadow, with shards primarily available through premium purchase paths and specific high-tier event rewards.
At equivalent investment level, Cynthia sits below Marlena in damage output. She is a meaningful fifth hero for accounts that have built the first four to competitive star levels and want to extend roster depth for multi-squad content.
SSR hero investment priority
SSR heroes are the competitive middle tier of Last Asylum: Plague. They are more accessible than URs, their shards available through the Alliance Shop, banner pools, and event rewards, and the right SSRs carry accounts from early game through mid-game competitive stages while UR investment accumulates.
Grenwald is the first SSR investment for accounts that do not yet have Marlena. As a Warlock carry, his Exorcism Spell passive increases damage dealt to monsters by the entire team, making him the strongest PvE damage option at SSR rarity. His glass cannon profile (high damage, low defense) requires a tank in front but once protected he is competitive across Rat Swarm, territory reclaim, and early PvP. Treat Grenwald as the primary carry while pulling toward Marlena, then as a strong flex damage option after Marlena is available.
Bella is the best Arthur replacement and the first SSR tank investment for accounts still working toward Arthur. Her kit reduces monster damage taken by the team and debuffs enemy attack power, providing meaningful survivability support in Rat Swarm that makes her a genuine Arthur alternative rather than a placeholder. If your roster has Bella and Grenwald before Arthur and Marlena, that is a playable foundation. Do not reroll past a few attempts if you get this pairing early.
Griffith is a Ranger Tank whose spirit snake aura significantly reduces monster damage across the squad. He functions as a strong second tank for accounts that have Arthur and want additional frontline durability. His Ranger classification means he can hold a second frontline slot without competing with Arthur's Warrior-type kit for synergy benefits.
Stellar is the only dedicated support hero with a healing ability in the current Last Asylum: Plague roster. Her passive (Final Starlight) heals the ally with the lowest HP upon her death, providing a clutch survival window in boss encounters where the team's endurance window determines whether the Rat King is cleared. Her ultimate buffs team damage against monsters. Stellar is the priority SSR support investment for Rat Swarm specifically.
Claire is a single-target specialist whose buff scales with the attack power of your three highest-attack heroes. This makes her value grow proportionally as your UR heroes develop. Her large sword AoE skill functions as both boss DPS and wave clearer. Claire's niche is boss-focused content where her single-target burst matters more than sustained AoE.
Bestar and Hastar are situational heroes. Bestar's bleed and DoT mechanics perform best in Reclamation territory fights where sustained damage accumulates across longer encounters. Hastar provides crowd control and burst that becomes more relevant in PvP than in PvE. Neither is a primary investment target until your core five are competitive.
Lucius and Sivir are viable flex replacements when core SSR options are not yet available. Neither justifies deep investment once Bella, Griffith, Stellar, Claire, or Grenwald are buildable.
Ash is the weakest SSR in the current meta. Her Physical single-target ultimate produces lower burst output than equivalent investment in other SSR carries. Skip when any other SSR option is available.
Best Last Asylum Hero Combinations and Lineup Synergy
Individual hero strength matters, but combination synergy determines actual squad output. The best Last Asylum hero combinations follow a consistent pattern: one anchor tank, one primary DPS carry, and flexible slots for support or secondary damage.
Standard meta lineup for Rat Swarm defense and boss content: Arthur (tank) + Marlena (DPS) + Griffith (monster damage reduction). This combination covers survivability, burst damage, and specialized boss defense. If you are building toward one squad, this is the composition to target.
Whale meta lineup for players with all UR heroes available: Arthur + Shadow + Marlena. Arthur reduces Physical damage (Earthshattering) and all damage to tanks (Strong Will). Shadow reduces Energy damage (passive + secondary ability). Marlena delivers burst damage from behind both tanks. Add Stellar (support) and a flex slot for the full 5-hero squad. This composition provides coverage against both damage types and is the strongest foundation for Hunt Battle, Kingdom War, and competitive PvP.
Alternative lineup without UR heroes: Bella (tank) + Grenwald (DPS) + Stellar (support). This SSR-based composition performs well for players building toward their first UR pulls.
For players running multiple squads, keep your strongest hero combination in your primary formation and distribute remaining heroes based on role coverage rather than raw tier ranking. Cynthia leads your second squad as the A-tier carry once your primary trio is complete.
Your budget should be working harder than it is...
Here is the multiplier most serious Doctors never think to optimize.
The hero investment decisions above determine which tier your roster operates at. There is a second variable most accounts leave unexamined: how efficiently your spend converts into Diamonds.
Most players buy through the App Store or Google Play at full retail price. For a single Doctor, the difference is manageable. For an alliance where 15 or more members are all paying full retail independently, that gap compounds into a meaningful amount of lost efficiency across a season. The same monthly budget, routed more efficiently, produces more hero copies, more banner pulls, and faster pity completion without anyone changing how they play.
Packsify routes purchases through official channels in a more efficient way than buying solo. Same packs, same in-game delivery, same official payment rails. The difference is at the system level. Your monthly investment produces more actual in-game value without touching your account, your alliance, or how you spend inside the game.
Last Asylum: Plague hero tier list FAQs
Who are the best heroes in Last Asylum: Plague?
Arthur (UR tank, S-tier, mandatory first investment) and Marlena (UR warrior carry, S-tier, mandatory second investment) are the best heroes in the current meta. Shadow (UR Ranger-Tank hybrid, S-tier, premium-gated) is the best third investment for accounts that have Arthur and Marlena at competitive star levels. For SSRs, Grenwald is the best damage dealer, Bella the best tank alternative, Stellar the best support.
What is the best hero in Last Asylum: Plague?
Arthur is the single most important hero in Last Asylum: Plague. His team-wide protection passive, HP-scaling shield, and AoE damage reduction ultimate make every other hero on your roster perform better. Without Arthur in the frontline, damage dealers absorb contact before they can output damage. He is the first investment at every spending level, with no exception.
Who is Harper in Last Asylum: Plague?
Harper is a UR support hero from the Warrior faction, available through the Daily Offer starting at server age 22 days. His ultimate increases all allied heroes' ATK by 21% for 5 seconds. His passive bubble skill reduces damage received by the lowest-HP ally. Harper is the fourth UR to build after Arthur, Marlena, and Shadow, because his ATK buff scales with the power of the heroes it buffs. A maxed Arthur, Marlena, and Shadow receiving a 21% ATK buff produces substantially more total squad output than the same buff applied to undeveloped heroes.
What are the best Last Asylum: Plague heroes for Rat Swarm?
Arthur (frontline protection), Marlena (burst damage, save ultimate for Rat King), Bella or Griffith (secondary tank), Stellar (support with healing passive), and Claire or Grenwald (flex damage). The key positioning rule: tanks in front, support in the middle, damage dealers in the back. Saving all active abilities through pre-boss trash waves and using them in the Rat King's first 15 seconds is the most impactful single tactic for clearing higher difficulty tiers.
What are the best Last Asylum heroes for PvP?
Arthur and Marlena remain the core for PvP. Hastar rises from its PvE ranking in PvP due to crowd control value. Shadow's Energy damage reduction passive provides a meaningful defensive advantage against Energy-based enemy compositions. Grenwald pairs with Marlena as a dual-carry option in PvP burst compositions. The meta will evolve with new hero releases.
How do I get UR heroes in Last Asylum: Plague?
Arthur and Marlena shards are available through Tavern recruitment (standard gacha banner), the Alliance Shop, and event rewards. Harper is available through the Daily Offer starting at server day 22. Shadow and Cynthia are premium-gated heroes whose shards come primarily through top-up rewards and premium purchase paths. Standard summons do not yield Shadow or Cynthia reliably.
Should I invest in SSR heroes or wait for UR pulls in Last Asylum: Plague?
Both. Grenwald, Bella, Stellar, and Griffith are competitive at SSR rarity and easier to star up than URs because copies are more accessible. Invest in strong SSRs while accumulating pulls toward Arthur and Marlena. The correct sequence: pull on Arthur and Marlena banners concentrating Diamond spend until pity is hit, then build Grenwald, Bella, and Stellar as support SSRs alongside UR development.
Is Last Asylum: Plague best team Arthur and Marlena?
Yes, as the core two. The full competitive best team is Arthur (tank, slot 1), Marlena (primary damage, slot 2 or 3), Stellar (support, middle), Griffith or Bella (secondary tank, slot 2), and Claire, Bestar, or Grenwald as the flex fifth. Swapping slot 4 and 5 based on game mode (more defense for Rat Swarm, more damage for territory, more burst for PvP) is the primary adjustment that does not require building new heroes.
