Choosing the right heroes in Last Asylum: Survival can make a huge difference in both PvE and PvP battles. While many tier lists simply rank heroes by rarity, that approach doesn’t always reflect their actual performance.
Some SSR heroes outperform others because of their skills, while certain heroes shine when paired with the right team composition. In most cases, skills matter more than raw stats, since attack, defense, and health can all be increased through gear, star upgrades, and other systems.
Last Asylum Plague Hero Tier List Guide – Best Heroes
This guide focuses on hero effectiveness based primarily on skill strength, battlefield role, and overall utility.
S Tier
These heroes offer exceptional power and strong abilities that make them core picks for most teams.
Arthur
Arthur stands out as one of the strongest tank heroes available. His kit focuses heavily on survivability and protection.
His abilities include strong shield mechanics that absorb damage and protect both himself and allied heroes. His ultimate skill deals heavy area damage while also reducing the physical damage taken by nearby allies.
This combination makes Arthur extremely valuable in both PvE fights and team battles. With massive health and defensive scaling, he becomes incredibly difficult to eliminate once fully upgraded.
For most players, Arthur is a reliable frontline anchor that can protect the rest of the team.
Marina
Marina is another top-tier hero thanks to her impressive offensive power and high damage potential.
Her abilities focus on energy damage and multi-target attacks. Her ultimate skill releases several sword waves that strike multiple enemies, creating strong burst damage across the battlefield.
She also gains bonus energy damage and cooldown reduction through her passive abilities, allowing her to use powerful attacks more frequently.
When paired with a strong tank like Arthur, Marina becomes a devastating damage dealer capable of clearing enemies quickly.
A Tier
These heroes are very strong and can perform extremely well with the right setup.
Bella
Bella is another tank hero and offers solid defensive abilities. She can reduce incoming damage and weaken enemy attack power, which helps protect the team during long battles.
Her ultimate skill deals heavy damage while lowering enemy attack, making her both a defensive and offensive asset.
While her skill set isn’t quite as powerful as Arthur’s, she still performs very well in most situations.
Grenwald
Grenwald is a classic glass-cannon damage dealer.
His abilities revolve around high spell damage and strong monster damage bonuses. One of his most effective skills deals damage to multiple enemies at once, which makes him extremely useful during PvE content.
Although his defense is relatively low, pairing him with a strong tank allows him to deal massive damage safely from the backline.
Stellar
Stellar brings strong support utility to the battlefield.
Her skills increase the damage allies deal to monsters, and she also has healing capabilities that can save allies during difficult fights. This makes her especially useful for PvE content and long battles.
While her base stats are not particularly impressive, her support abilities make her a valuable addition to many teams.
Claire
Claire is a strong offensive warrior hero with several powerful damage skills.
Her abilities include rapid multi-hit attacks that deal heavy damage to a single target, making her particularly effective against bosses. Her ultimate skill also deals strong area damage, giving her flexibility in combat.
Because of her balanced skill set, Claire performs well in both boss fights and normal battles.
Griffith
Griffith offers an interesting mix of defense and utility.
One of his standout abilities reduces monster damage taken by allies, which can greatly improve team survivability in PvE content. His offensive abilities are also stronger than many other tank characters.
This makes him a versatile hero that can contribute both protection and damage.
A– Tier
These heroes are still powerful but may require specific team setups to perform at their best.
Bestar
Bestar is a ranged damage hero with strong bleed mechanics.
Her ultimate ability deals area damage while applying a bleed effect that continues damaging enemies over time. She also has a passive ability that increases damage against bleeding enemies, which creates strong synergy within her own skill set.
Because of this bleed-focused design, she can deal impressive sustained damage during longer fights.
Hastar
Hastar combines tank durability with strong magical damage abilities.
His ultimate attack deals extremely high damage to enemies in front of him, making him dangerous in close combat. He also has a defensive skill that grants a shield when his health drops below a certain threshold.
While some of his skills are less impressive, his ultimate ability and defensive mechanics make him a reliable frontline fighter.
B+ Tier
These heroes can still perform well but may not be as consistently powerful as higher-ranked characters.
Celia
Celia is a support-oriented hero who specializes in monster damage bonuses.
Her abilities include multi-target attacks and buffs that increase damage against monsters. This makes her useful for PvE activities such as farming and boss fights.
However, her overall support capabilities are somewhat limited compared to other heroes.
Kesso
Kesso focuses on single-target damage and offensive abilities.
He can summon a war eagle to assist him in combat, and his passive ability boosts his attack power when his health drops below a certain threshold.
Although he can deal decent damage, his skill set doesn’t provide as much versatility as other carry heroes.
Severe
Severe is another offensive hero designed to deal strong damage to individual enemies.
Her skills include multi-target attacks and attack power boosts, allowing her to maintain solid damage output. However, she lacks the unique mechanics or support capabilities that would push her into higher tiers.
Lucius
Lucius is a tank hero, but his abilities lean more toward offense than defense.
Many of his skills focus on dealing damage rather than protecting allies, which makes him less effective in the traditional tank role. Because of this, other tanks tend to outperform him in most situations.
B Tier
These heroes can still be used early in the game but are often replaced by stronger options later.
Ash
Ash is a ranged damage hero with decent base stats but relatively weak skills.
While she can attack multiple targets and increase her attack power through passive abilities, her ultimate skill doesn’t provide the same level of impact as other heroes.
Because of this, she tends to fall behind stronger damage dealers in later stages of the game.
Heroes Usually Skipped
SR heroes (blue rarity) are generally not included in most tier lists because their long-term potential is significantly lower than SSR and UR heroes.
Most players replace them fairly quickly once stronger heroes become available.
Best Team Composition Strategy
Instead of focusing only on individual heroes, it’s often better to build a balanced team.
A strong lineup usually includes:
- A durable tank to absorb damage
- One or two carry heroes to deal damage
- A support hero to provide buffs or healing
For example, a combination like Arthur + Marina + Grenwald + Stellar creates a team with strong defense, high damage output, and support abilities.
In Last Asylum: Survival, hero strength depends heavily on skill synergy and team composition rather than rarity alone.
Ultra-rare heroes like Arthur and Marina naturally dominate due to their powerful abilities, but several SSR heroes also perform extremely well when used correctly.
Understanding how each hero’s skills function — and pairing them with the right teammates — is the real key to building a powerful squad.
