The Pandemic Experience is a recurring bi-weekly combat trial: you fight waves of “Hell Nurses” of rising difficulty — Level 1 through Level 9 — and both you and your alliance climb together. The deeper your alliance goes, the more bosses open up. Rewards scale with difficulty: UR Omni Shards, Raven Essence, and diamonds.

How Progression Works

You start at Difficulty 1. Beat it → Difficulty 2 unlocks. The event returns roughly every 2 weeks, so you climb one or two levels per cycle.
Level 9 is the wall — squad power requirements get steep (~tens of millions of Might).
Alliance milestones: the next boss unlocks when enough members (e.g. 40 players) clear current top difficulty. If you stop pushing, you stall the whole alliance.
Records tab shows where every member stands — use it to see who needs a push.

Rewards

UR Omni Shards (the awakening currency)
Raven Essence (the permanent Raven bottleneck)
Diamonds and speedups: nice, but they’re the cherry, not the cake

Climb as high as you can every cycle: reward volume scales with the difficulty reached.

Beating High Difficulty: Pro Tips

1. Swap UR gauntlets for SSR gauntlets

Same World Boss trick: SSR gloves carry bonus damage vs monsters which matters more than raw UR ATK on PvE targets. Swap before starting.

2. Enable War Frenzy first

Scout any player → triggers the War Frenzy buff (extra attack) that also applies in this event. Costs you one scout, saves you wounded troops.

3. The Weak-Hero Rally Trick

Your own squads hit the wall at high difficulties? Use rallies to borrow teammates’ power:

Empty a slot: put one weak, low-level hero alone in a rally squad.
Launch 3 rallies at the same time at 3 nurses.
Strong ally players (whales/spenders) join and annihilate the nurse.
Your squad takes minimal losses — your Infirmary stays empty.

~10 minutes and 2–3 weak heroes is all it costs.

4. Coordinate the timing

Agree in alliance chat on a shared window: everyone pushes, whales are online to absorb rallies, and 40-member checklists get cleared within an evening.

The Only Real Mistake

Stopping mid-ladder. A player parked at Difficulty 7 while the alliance sits at 9 is dragging everyone’s unlock progress. Push every cycle — even with rallies and helpers, your difficulty count is what the alliance gates on.

What's up, guys? Corpus Gaming here, and today we have another guide for you. We are going to talk about the Pandemic Experience. We're going to talk about

some tips and tricks that you can use on this event to clear it out pretty fast and to help out your alliance. You know what to do. If these guys help you,

smash that like, hit that subscribe, and let's get into it. So, we before we start with the tips, we're just going to look real quick through what is Pandemic

Experience. It is basically a challenge you can do, and you start with one, and after you have cleared one, you can start with two after 2 weeks when the

event arrives again. Then you go to three, four, and it goes all the way to the back uh to nine. And once you reach nine,

it's going to be really difficult. As you can see, uh your squad power needs to be 3 million. I mean, uh 30 million, and you really need uh allies to help

you out. But, of course, you can also do that if you're weaker, and that's that also where the tips is going to be for.

So, we'll go through that after we have cleared out this cleared out this uh and this is really an important event to do cuz you get a lot of rewards. You get

the UR Uni shards, and of course, the Raven essence that is really going to help you uh progress your account. And of course, the diamonds are nice, but

they're not really mentionable. Um and also, why you need to clear as high as possible cuz the more uh levels the alliance clears, the more these bosses

will open up. And is as you can see down here, unlocks after 40 players have passed the difficulty of level nine uh or higher difficulty challenge. And

now there are 21 people who cleared it.

Uh this is a the first day, so we'll definitely clear all nine. Um but, we do need to help each other, and that's also where strong alliance uh comes forward.

And here you have a record tab, so you can see where everyone is uh in uh the game. And as you can see, a lot of people are at difficulty nine.

Some are at seven. They forgot to push forward and now are slacking behind. So, if you want to help your alliance, always push forward to the next level.

And that's it for this event. We are going to do nine as well, so I'm going to press that. And then these hell nurses show up. And first it's going to

be quite okay to do them alone cuz they have 13 mil power. That's not that good.

Um but later on they will get more difficult and they will pop up three at a time. And I will do a little little bit of off-screen killing till we get to

the hard part and then I'm going to explain to you guys how we can complete this solo and how to ask for help from your alliance. So, let me just

fix this real quick.

A few moments later.

All right, we are now at the last 10 nurses. I'm just going to show you guys a few tips on how to really improve your odds at completing this event. And

for the free-to-play players, don't worry. You guys can definitely complete this as well with some help, of course. Let's go

straight to the few points right now.

And the first one is as follows. We want to, of course, as we have seen in the world boss videos, we want to change up our UR gauntlets and we want to get

these SSR gauntlets on them so we can deal more damage. And that is really going to help us as well to complete going to help us as well to complete this

event. And what else can we do? We can also scout someone to unlock the frenzy buff. And the frenzy buff is going to give us some extra attack as well. And

as you can see, the frenzy buff has been activated right now. And we are going to attack this nurse. And let's look at the

difference that we get from attacking this. Of course, this one is a little bit stronger than the previous one, but I think the difference will be big. And

let's look at it. We have the report right here. This is the level 20 nurse. And it is okayish. We're still surviving that one. Uh uh And here is the level

21 nurse, of course, really stronger as well, but the damage output is a lot more. So, you will lose less troops this way. The next trick that we can show you

as well is as followed. Let me just set up my squads real quick and I'll be right back. So, what we are doing here right now is we have all our squads

ready and we have asked some help from the alliance members, a stronger will or spender that's going to help us out. And what you want to do is you want to put

one weak hero here to really just activate the rally. And you use one with a low level so you don't use lose a lot of troops as well. So, you only lose a

little bit of troops and this keeps your hospital low and gets you a lot of resources. And what you want to do is you want to search for these nurses and

you want to start rallies. And the fastest way possible is to just do three at a time and then three people or three wills will join to help you out

with these nurses and you can really complete this event quite easy. As you can see now, a lot of people are joining into my rally and this is basically how

you can also help each other out as an alliance. Let's do a quick break and I'll be right back and I'm going to complete this event right now

and and that will also end the video and this guide, of course.

So, we are going to continue and we have sent out our rallies and people are of course joining straight away to help out and this goes quite fast, actually. So,

I just think that it's nice to see it live on the on the video as well. So, you guys can really see how fast this can be done. And here we go. We have

can be done. And here we go. We have completed a few more. We're going to complete this one and we are now at 27. Three more to

go and we are going to start the last rallies and that's complete this event as well for this week. I've got a lot of resources. I've helped my alliance and

it cost me almost nothing and not even time because I've been doing this for 10 minutes and the last part took me maybe 2 minutes. If you have a good active

alliance or an active community and just make an plan when you are going to do this events all together. But this is really the best way to do this. And I

hope this guide has been helpful for you to complete this guide this event and if it did say something in the comments smash that like hit that subscribe and

see you guys in the next guide. Bye-bye.

❓ FAQ — Frequently Asked Questions

What is the best F2P team in Last Asylum: Plague?

The canonical F2P squad is Arthur, Daskal, Marlena, Harper, Claire (all Warriors — mono-faction gives +20% HP/ATK/DEF). Arthur is free from day 1; the $1 Marlena top-up is considered the best value in the game. Daskal arrives in the first Era of Revival season (day 120+).

What should I upgrade first?

Sanctuary first, always — it gates every other building and your hero level cap. Then Training Grounds, Barracks, Research Lab, Infirmary, Wall. Keep the Builder’s Hut at Sanctuary level until Sanctuary 15 for free construction speedups.

When does Marlena unlock?

Day 66 for free — or immediately via the $1 starter top-up. Save UR shards so she lands at 8★ right away, then push 10★.

How do I get Cynthia as F2P?

Cynthia arrives via the Wishing Wheel on day 8. Save diamonds from day 1 (skip everything else) — ~11,500 diamonds total, and always spin ×10 (single spins waste tokens).

How do I get antitoxin?

Antitoxin Workshop + Stable production, every building upgrade completion, Falcon Quests (nearly all of them), Covert Ops and Caravan Trade (including plundering others’ ops — up to 5/day), and Blight/Elite Blight hunts (10/20 stamina). Events pay large amounts.

Why did my plunder income drop to almost nothing?

You hit the daily plunder limit: below the limit 100%, from 1× the limit you keep only 15%, from 1.3× only 5%. It resets at 02:00 UTC. The limit scales with Sanctuary level (2.5M at Lv.10–12 up to 30M at Lv.30) and rises immediately when you upgrade Sanctuary. A yellow triangle under your Might shows the status.

What should I buy in the shops?

Sanctuary/Expedition/Alliance shops: Crow Essence and UR Hero Omnifragments first. Honor shop is for gear blueprints only (never epigraph chests there). All shops restock Monday.

Are diamonds worth spending on speedups?

Only the VIP-shop 8h speedups are considered acceptable purchases — and only after hero resources. Community rule: never dump diamonds into speedups over hero wheel events (Cynthia day 8, Joker after day 15).

What faction should I build?

Warriors are the best early game (free Arthur/Harper shards, $1 Marlena). Rangers peak mid game (counter Warriors). Warlocks are the best late game but need heavy long-term investment. Mono-faction (5 heroes of one type) is the current meta because UR epigraphs buff a single faction.

How does Claire SSR→UR conversion work?

Opens on Era Day 8. She lands at 6★ and the run to 10★ costs 1,600 SSR shards (each substage costs 2× the SSR price). There’s a team-buff dip between 6★–9★ — skip it by banking Hall of Honor levels before converting (Lv.60→8★, Lv.100→9★, Lv.160→instant 10★).

How do I redeem gift codes?

In-game: Avatar (top-left) → Settings → Gift Code. iOS or web: log in at the official redemption page with your linked Facebook/Google account, pick server and character, enter the code.

What are the biggest beginner mistakes?

Upgrading everything equally instead of one main squad; judging heroes before high stars (Marlena is the classic late bloomer); splitting Awakening materials across heroes; wasting gems on VIP levels over hero wheels; skipping daily plunder (~27M resources/day); letting stamina cap.
