If you want to survive the Rat King bosses and relentless swarms in Last Asylum: Plague, you can't afford to waste resources on weak units.

These two UR heroes from the Last Asylum: Plague tier list can form the backbone of the strongest squads right now.

Arthur is the unbreakable frontline. His passive reduces damage taken by allied tanks, his active generates a massive shield based on his max HP, and Arthur’s Earthshattering ultimate slams the ground for AoE damage while cutting incoming damage for nearby allies. In Rat King fights and long swarm waves, he keeps your entire squad alive longer than any other tank. Build him first, no exceptions. Arthur is the safest long-term investment you can go for in this gameplay.

Marlena is your primary damage dealer. She unleashes sword winds that strike random enemies for heavy energy damage, her passive boosts all energy damage she deals, and Marlena’s cooldown reduction lets her spam abilities relentlessly. Position her safely behind a tank and watch her delete priority targets or clear waves.
These SSR heroes from our Last Asylum: Plague characters tier list can shine when you don’t have both UR units yet or need specific utility.
Grenwald (Warlock Carry – SSR): A true glass cannon. Low defense but terrifying magic damage output through single-target spells and AoE soul magic. His passive increases damage dealt to monsters, making him perfect for PvE. Grenwald needs a strong tank in front (Arthur or Bella), but once protected he melts bosses and swarms.

Bella (Warrior Tank – SSR): The best Arthur alternative is Bella. She swings a giant axe for heavy physical damage while her skills reduce monster damage taken by the team and lower enemy attack power. The ultimate of Bella’s hits hard in an area and debuffs enemies and will be ideal for sustained fights and a fantastic second tank if you pull Arthur later.

Grifith (Ranger Tank – SSR): Grifith is a ranged tank with a unique spirit snake aura that significantly reduces monster damage across your squad. He also delivers strong single-target burst. Grifith is the specialist pick for high-difficulty Rat King encounters and territory reclamation where monster pressure is relentless. His aura has less impact in pure PvP, but he’s still a top-tier utility hero.

These heroes work well in the early-to-mid game or as flex picks while you build your core.
Hastar (Warlock Tank – SSR): A hybrid tank with crowd control. His ultimate delivers massive frontline damage, and he gains a defensive shield at low HP plus knock-up and stun effects. This one is great for disrupting enemy waves or adding offensive pressure from the front line.

Stellar (Warlock Support – SSR): Stella is a true support in a game where healing is scarce. Her ultimate buffs the whole team’s damage against monsters, and when she dies she heals the lowest-HP ally. Solid early-game damage buff and clutch survival tool. Use Stellar in your SSR-only squads until you replace her with stronger options.

Claire (Warrior Carry – SSR): Claire’s rapid multi-hit attacks that shred single targets, especially bosses. Her AoE ultimate and passive monster damage boost make her a strong flex DPS for focused burst phases.

Bestar (Ranger Carry – SSR): This one is a bleed specialist. She applies damage-over-time effects with her active and ultimate (ghostly cats that hit multiple enemies), and her passive ramps up damage against bleeding foes. Excellent for longer engagements where DoT stacks up.

These can fill gaps early but fall off quickly.
Kesso (Warrior Carry – SSR), Sivir (Warrior Carry – SSR), Lucius (Warrior Tank – SSR), and Celia (Warrior Support – SSR) offer decent single-target or multi-target tools and some monster bonuses, but they lack the scaling, utility, or synergy of higher tiers. Use them only if you’re still building your first strong squad and have no better SSR options.

Ash (Ranger Carry – SSR) lands in D tier because her physical damage and single-target ultimate feel underwhelming compared to other carries. She works in the very early game but gets replaced fast.

E Tier (Robin, Durant, Kafa, William – mostly SR) are basic starter heroes with low scaling and simple kits. They’re fine for your very first hours but should be benched the moment you pull any SSR or UR unit.
Yes, if you’re in the first 24–48 hours and haven’t progressed far. Rerolling for Arthur or Marlena (or both) gives a massive head start because early upgrade materials are scarce. If you get Bella + Grenwald instead, that’s still a very playable account and stop rerolling after a few tries to avoid wasting time.
Slightly yes. PvE (Rat Swarms and Rat King) heavily favors Grifith’s monster damage reduction aura and bleed/DoT heroes like Bestar. Pure PvP or alliance duels value burst damage and crowd control more, so Hastar or Claire can rise in value while Grifith drops a bit. The core S-tier pair still reigns in both.
