For Last Asylum: Plague players investing $1,000+/month who want the definitive Arthur build — every skill name, exact scaling, gear sequencing, and the team pairings that turn him from a good tank into the anchor your entire account scales around.
Before you build Arthur in Last Asylum: Plague, understand what you're actually building...
Arthur is not just the best tank in Last Asylum: Plague. He is the hero your entire squad's survivability depends on. Every other hero on your roster — your DPS carries, your support, your specialists — performs better or worse as a direct function of how well Arthur is built. A half-invested Arthur means your Marlena dies mid-fight, your Grenwald gets one-shot in late Rat Swarm waves, and your alliance warfare squads collapse before they deal meaningful damage.
This guide covers the complete Arthur build: all five skills with exact scaling, skill priority order, gear investment sequencing, star rank breakpoints, the team compositions that maximize his kit, and where he performs across every game mode. If Arthur is your first hero investment (and he should be), this is the build path that ensures that investment compounds correctly.
Meet Arthur in Last Asylum: Plague...
Arthur is a UR (Ultra Rare) hero from the Warrior faction, Tank class. He is the first hero available in the Tavern, though as a server ages more heroes enter the pool and his pull rate decreases. At max level his base stats sit at 15,971 ATK, 2,236,301 HP, 15,971 DEF, and 350 CMD.
Arthur is the only hero in Last Asylum: Plague whose entire kit is designed around team-wide damage mitigation. Other tanks absorb damage for themselves. Arthur absorbs damage for the entire squad. He has five skills — an auto attack, an ultimate, an active, a passive, and a support skill that unlocks at Level 30 with 8⭐.
Last Asylum: Plague Arthur Full Skill Breakdown
Battle Shield (Auto Attack)
Swings his shield, dealing 750% ATK Physical DMG to a single enemy. Star upgrades increase the damage significantly: +40% extra damage at 1⭐, scaling to +100% at 5⭐, and +200% at 10⭐. This is Arthur's basic attack cycle. It won't top damage charts, but at high star ranks the 200% extra damage bonus means Arthur's auto attacks contribute meaningful chip damage between ability rotations — more than most players expect from a tank.
Earthshattering (Ultimate Skill) — Cooldown: 6.4s
Slams the ground with his shield, dealing 1407.5% ATK Physical DMG to all enemies within range and reducing Physical DMG taken by allies within range by 32.5% for 5 seconds. Star scaling: +3% Physical DMG reduction at 2⭐, +4.5% at 6⭐, +7.5% at 10⭐. At 10⭐, that's a total of 47.5% Physical DMG reduction for your entire squad for 5 seconds.
Two critical details most guides miss: the damage reduction is Physical DMG only, not all damage types. In PvP where enemy heroes deal Energy or Magic damage, Earthshattering's mitigation is partial, not total. And the 5-second window is short — timing it to cover your DPS heroes' burst window or to absorb a Rat King's heavy slam is the difference between wasted and optimized use.
Rock Solid (Active Skill) — Cooldown: 4.5s
Grants a shield equal to 25% of Arthur's current max HP, absorbing 50% of damage taken each time, lasting for 3 seconds. Star scaling: shield effect +20% at 3⭐, +30% at 7⭐, +50% at 10⭐.
Key mechanical detail: the shield absorbs 50% of incoming damage per hit, not 100%. Arthur still takes the other 50% through the shield. This means Rock Solid extends Arthur's effective HP pool rather than making him invulnerable. At 10⭐, the shield effect bonus reaches +50%, which pushes the base shield value to 37.5% of max HP — with Arthur's 2.2M+ HP pool, that's a shield absorbing over 400K damage every 4.5 seconds. On a 4.5-second cooldown, Rock Solid can be cycled almost continuously during sustained fights.
Strong Will (Passive Skill)
In combat, reduces all damage received by allied tank heroes by 8.25%. Star scaling: +0.6% at 4⭐, +0.9% at 9⭐, +1.5% at 10⭐ — totaling 11.25% damage reduction for all allied tanks at max stars.
This is the skill that separates Arthur from every other tank in the game. It doesn't just protect Arthur — it protects every tank on your team. In compositions running Arthur alongside Griffith or Bella, Strong Will's value multiplies across your entire frontline. The reduction is all damage types (Physical, Energy, Magic), unlike Earthshattering which only covers Physical.
Tenacity (Support Skill) — Unlocks at Level 30 + 8⭐
ATK, HP, and DEF +20%. Skill cooldown speed +10%.
This is Arthur's hidden power spike and the reason pushing him to 8⭐ is non-negotiable for serious spenders. A flat 20% increase to all three core stats at once is massive — it makes his shield larger (more HP), his damage reduction more durable (more DEF), and even his auto attacks and Earthshattering hit harder (more ATK).
The 10% cooldown speed means Rock Solid cycles faster, Earthshattering comes off cooldown sooner, and Arthur's uptime on protective abilities increases across the board. Tenacity alone justifies prioritizing Arthur's star rank above every other hero on your roster.
Last Asylum: Plague Arthur Skill Priority
Priority 1 — Strong Will (passive). Every upgrade here returns value across your entire frontline. The 8.25% baseline reaching 11.25% at max stars applies to every allied tank in every fight, every mode, permanently. Max this first.
Priority 2 — Rock Solid (active). The shield scales with Arthur's max HP. At 10⭐ the shield bonus reaches +50%, creating a 400K+ damage buffer every 4.5 seconds. This is your primary survivability tool. Level this second.
Priority 3 — Earthshattering (ultimate). 1407.5% ATK damage plus up to 47.5% Physical DMG reduction for allies at 10⭐. The burst and mitigation window is strongest in Rat King encounters and wave-clear scenarios. Level third.
Priority 4 — Battle Shield (auto attack). The 200% extra damage at 10⭐ is meaningful but Arthur's primary value is protection, not damage. Upgrade after the three core abilities.
Priority 5 — Tenacity (support skill). This unlocks automatically at Level 30 + 8⭐. No manual leveling required, but reaching 8⭐ as fast as possible is the goal, since the 20% stat boost and 10% cooldown reduction activate the moment you hit the threshold.
Last Asylum: Plague Arthur Gear Priority
Gear investment on Arthur follows a single principle: maximize HP and defense first. Arthur's value comes from Rock Solid's shield scaling (which scales off max HP) and Strong Will's damage reduction (which scales with survivability). Every gear slot should prioritize:
HP gear first. Rock Solid generates a shield equal to 25% of max HP (37.5% at 10⭐). Every point of HP on Arthur directly increases the damage his shield absorbs every 4.5 seconds. With Tenacity's +20% HP bonus on top, HP gear on Arthur compounds twice.
Defense gear second. Flat damage reduction that stacks with Strong Will's percentage reduction. Defense gear on Arthur effectively reduces damage twice — once from the gear stat, once from the passive multiplier.
Ignore attack stats. Arthur's job is not to deal damage. If you're allocating gear resources to increase Arthur's ATK, you're investing in the wrong output. That budget belongs on Marlena or Grenwald. The only exception: once Tenacity is active, Arthur's ATK matters slightly more for Earthshattering's 1407.5% multiplier, but it's still lower priority than HP and DEF.
Upgrade gear to purple rarity and above as soon as materials allow. The jump from blue to purple gear on Arthur produces a more noticeable squad-wide survivability improvement than the same gear upgrade on any other hero.
Last Asylum: Plague Arthur Star Rank Breakpoints
Star rank upgrades increase Arthur's base stats and unlock skill scaling bonuses at specific thresholds. The critical breakpoints:
3⭐: Rock Solid shield effect +20%. First meaningful survivability spike.
4⭐: Strong Will effect +0.6%. Your frontline gets more durable.
8⭐: Tenacity unlocks. This is the single biggest power spike on Arthur — ATK/HP/DEF +20% and skill cooldown speed +10%. Everything about Arthur gets better at once. For serious spenders, reaching 8⭐ should be treated as a hard milestone, not a nice-to-have.
10⭐: All skills reach maximum scaling. Battle Shield +200% extra damage. Earthshattering +7.5% Physical DMG reduction (47.5% total). Rock Solid shield +50% (37.5% of max HP). Strong Will +1.5% (11.25% total). Arthur at 10⭐ is the most dominant hero state in the game.
Arthur fragments are available through standard summon banners, the Alliance Shop, and certain event rewards. Prioritize purchasing his fragments in every source until 8⭐ minimum, then continue to 10⭐.
Best Team Pairings for Arthur in Last Asylum: Plague
Arthur anchors every competitive composition in Last Asylum: Plague. The heroes around him change based on game mode, but Arthur's slot 1 position does not.
Arthur + Marlena (primary DPS pairing). This is the core duo for most content. Arthur's Earthshattering Physical DMG reduction window is the ideal moment for Marlena to deliver burst damage safely. Together they handle Rat Swarm waves, Rat King encounters, and PvP engagements. Build both before expanding your roster.
Arthur + Marlena + Griffith (Rat Swarm / boss specialist). Griffith's spirit snake ability reduces monster damage taken by nearby allies, which stacks with Strong Will's all-damage reduction. This triple creates the most durable frontline available for PvE content. Add Stellar (support) and a flex DPS in slots 4-5.
Arthur + Grenwald (alternative DPS pairing). If Marlena isn't available, Grenwald provides high magic damage from the backline. Arthur's protection is especially critical for Grenwald, whose low HP and defense stats make him vulnerable without a strong frontline.

Where Arthur Performs Across Last Asylum: Plague Game Modes
Rat Swarm (tower defense): Arthur is essential. Earthshattering's 32.5-47.5% Physical DMG reduction keeps your squad alive through late waves where enemy damage spikes. A maxed Arthur is the difference between clearing Rat King and wiping on the pre-boss wave.
Territory Reclamation: Rock Solid's 4.5-second cooldown means Arthur can cycle shields almost continuously through extended plague ruin encounters. His sustained tankiness allows full clears without hero losses.
PvP and Alliance Warfare: Strong Will's all-damage reduction protects your frontline against all damage types, while Earthshattering covers Physical specifically. In alliance events like Hunt Battle and Alliance Duel, a fully built Arthur directly increases your squad's output by keeping DPS heroes alive longer. Note that Earthshattering's reduction is Physical-only — in PvP against Energy/Magic dealers, Strong Will and Rock Solid carry the defensive load.
Your Arthur Build Compounds When the Infrastructure Behind It Does Too

At $1,000+/month, the total resource volume flowing into your primary tank build is substantial, and every dollar of inefficiency in how those resources enter the game is a dollar that doesn't become hero power.

A quick breakdown...
- Arthur is a UR Warrior-faction Tank with five skills: Battle Shield (auto), Earthshattering (ultimate), Rock Solid (active), Strong Will (passive), and Tenacity (support, unlocks at Lv30 + 8⭐). Build him first, before any DPS or support hero.
- Skill priority: Strong Will (passive, 8.25-11.25% all-damage reduction for allied tanks) first, Rock Solid (active, HP-scaling shield every 4.5s) second, Earthshattering (ultimate, 1407.5% ATK AoE + 32.5-47.5% Physical DMG reduction for 5s) third.
- Gear priority: HP first (Rock Solid shield scales off max HP), Defense second, ignore ATK stats. Arthur's job is protection, not damage.
- 8⭐ is the critical breakpoint — Tenacity unlocks, giving +20% ATK/HP/DEF and +10% cooldown speed. Treat this as a non-negotiable milestone.
- Core pairing: Arthur + Marlena covers tank + burst DPS for most content. Add Griffith for Rat Swarm specialist compositions where Strong Will + Griffith's monster damage reduction stack.
- Earthshattering's damage reduction is Physical DMG only. In PvP against Energy/Magic heroes, Strong Will and Rock Solid carry the defensive load instead.
- At 10⭐ with Tenacity active, Arthur is the most dominant hero state in the game. No other tank at equivalent investment outperforms him in any mode.
Arthur is the foundation your entire account scales around. Build him to 8⭐ before building anything else.
