Last Asylum: Plague UR Heroes Guide: Who to Build First

For Last Asylum: Plague players who want to know which UR heroes deserve their monthly budget, and in what order.

Last Asylum: Plague now has four UR heroes: Arthur, Marlena, Shadow and Cynthia. Each one costs a lot of resources to max.

Even accounts that buy packs every month cannot build all four at once without spreading so thin that none of them reach competitive level. The real question is which one gets your budget first, second and third, and which one can wait.

This guide ranks every UR hero by build priority, covers what each one does at max potential, and explains why the build order matters as much as the heroes. For the full list including SSR heroes, see the hero tier list.

UR hero build priority

Priority 1: Arthur (tank, Warrior faction), S tier

Arthur is your first investment. He is the only UR tank in standard summons from day one. His shards show up in the Tavern recruitment pool, the Alliance Shop and event rewards. That makes him the easiest UR hero to max, and he is also the most impactful.

His kit gives team-wide tank damage reduction (Strong Will), an HP-scaling shield on a 4.5-second cooldown (Rock Solid) and AoE Physical DMG reduction for allies (Earthshattering). At 8 stars he unlocks Tenacity, which boosts ATK, HP and DEF by 20% and skill cooldown speed by 10%. That one threshold takes him from strong to dominant. Every other hero on your roster performs better behind a maxed Arthur.

For the full skill breakdown and gear priority, see the Arthur build guide.

Priority 2: Marlena (carry / DPS, Warrior faction), S tier

Marlena is the highest single-target burst damage dealer in the game. Her kit is built to remove priority targets before they threaten your squad. She scales very well with upgrades, and her damage gets much bigger at higher star ranks.

Her shards come from summon banners and some event rewards. She is harder to max than Arthur, who has more shard sources, but she is worth every fragment. Arthur and Marlena together form the core duo for Rat Swarm waves, Rat King fights, territory reclamation and PvP. Start Marlena as soon as Arthur reaches a functional level, at least 5 to 6 stars.

You need a carry to turn Arthur's survivability into kills. Without Marlena, your squad lives but does not kill fast enough. Without Arthur, Marlena dies before she can deal damage. Together they solve both problems.

Priority 3: Shadow (Ranger and tank, Ranger faction), S+ tier potential

Shadow is the newest UR hero and arguably the most stat-loaded hero in Last Asylum: Plague. He is the only hero whose max HP goes over 1 million at full build. He is a Ranger and tank hybrid with a kit that does everything.

• Auto attacks: three separate projectiles per cycle, each dealing 210% ATK damage. One of the highest auto-attack outputs in the game.
• Ultimate: 462% ATK AoE damage, and he takes less damage for 3 seconds.
• Second ability: a 922.5% ATK AoE hit that also cuts enemy Energy damage by 40.2% for 5 seconds.
• Passive: allies take 22% less Energy damage. This is a permanent team-wide buff that covers the gap Arthur's Earthshattering leaves, since Earthshattering only reduces Physical damage.

Shadow is a premium hero. His shards come from top-up rewards and premium purchase paths, not standard summons. For accounts that buy packs every month, that is not a wall. It is a question of timing. Build Shadow after your Arthur and Marlena core is functional.

His Energy damage reduction stacks with Arthur's Physical damage reduction, so your squad is covered against both damage types. He also brings damage that rivals dedicated carries while being tankier than any of them. But he needs your Arthur base in place first.

Priority 4: Cynthia (carry / DPS, Ranger faction), A tier

Cynthia is the second UR carry next to Marlena. She deals strong damage and has a solid kit, but at the same investment Marlena beats her in most cases across Rat Swarm, boss content and PvP.

Her shards come from VIP shop purchases, certain badge exchanges and event reward cycles. The Wishing Wheel also gives Cynthia shards at a 10% chance per spin, with rarer 2-shard and 5-shard drops at lower odds. She is easier to get now than at launch, and her shard supply will likely keep improving.

Cynthia is not a bad investment. But every resource that goes to her before Arthur, Marlena and Shadow are functional is a resource not going to heroes that give you more competitive value. Build her as your second-squad carry once your main squad is complete.

Alliance leader playbook

If you lead an alliance, the UR question goes beyond your own account. Your members' hero builds decide how alliance warfare goes.

• Every member needs Arthur first. An alliance where every member has a functional Arthur does much better in Hunt Battle, Alliance Duel and territory defense than one with scattered hero investment.
• Marlena second for your main combat members. Your top 10 to 15 members who take part in alliance warfare should go Arthur, then Marlena. Support members focused on gathering can push Marlena back in favor of economy progression.
• Shadow as a force multiplier for your top accounts. When your R5 and top R4s add Shadow, the alliance's damage type coverage improves, because his Energy damage reduction fills the gap that Arthur's Physical-only Earthshattering leaves.

Quick summary

• Last Asylum: Plague has four UR heroes: Arthur, Marlena, Shadow and Cynthia. Build order matters more than having all four at low star ranks.
• Arthur first (S tier tank, most accessible shards, team-wide protection that makes every other hero better). Marlena second (S tier DPS, highest burst damage, core duo with Arthur).
• Shadow third (S+ potential, over 1 million HP hybrid, Energy damage reduction that covers what Earthshattering does not). Cynthia fourth (A tier carry, strong but beaten by Marlena at the same investment).
• Shadow shards come from top-up rewards and premium purchase paths. Cynthia shards come from the VIP shop, badge exchanges, event rewards and the Wishing Wheel.
• Shadow's Energy reduction plus Arthur's Physical reduction covers both damage types for your squad. That is why both are worth building.
• Alliance leaders: Arthur first for all members, Marlena second for combat members, Shadow for your top accounts.

Build order is the strategy. The heroes are the same for everyone. The sequence is where competitive accounts pull ahead.
