Pandemic Experience is a Challenge event in Last Asylum.
There are two types of Challenges in this event:
- Personal Challenges
- Alliance Challenges
1. Personal Challenges
Personal Challenges can be completed individually or with the help of your Alliance members.
When the event starts, players can complete challenges by defeating different enemies. Personal Challenges require players to defeat Hell Nurses.
Each difficulty contains 30 Levels of Hell Nurses that must be defeated before the next difficulty is unlocked during the next phase of the event.
There are 9 difficulties in total for Personal Challenges.
2. Alliance Challenges
Alliance Challenges require players to defeat Boss Enemies. These enemies are significantly stronger and require Rallies to defeat.
Alliance Challenges can only be initiated by R4/R5 Alliance members.
There are 9 difficulties in total for Alliance Challenges.
A certain number of Alliance members must complete the required Hell Nurse difficulty before the corresponding Boss difficulty can be activated.

Strategy & Tips
1. Complete the Highest Difficulty Available
Always complete the highest possible difficulty for your Personal Challenge as early as possible.
Your progress directly helps your Alliance meet the requirements for unlocking higher-difficulty Alliance Challenges. The faster members progress through the Hell Nurse difficulties, the sooner the Alliance can unlock stronger Boss Challenges.
2. Know When to Fight Individually or Rally
Learn when to progress individually and when to work collectively with your Alliance members.
Even if you are strong enough to defeat an enemy on your own, you should consider launching or joining a Rally if your troops are taking heavy losses.
Using Rallies can help:
- Reduce troop casualties.
- Reduce the number of troops that need healing.
- Save Speed-Ups.
- Save resources used for healing.
In some situations, completing a challenge through a Rally is more efficient than defeating the enemy individually.
3. Ask for Alliance Assistance
If the Hell Nurses are too strong for you to defeat individually, ask your Alliance members for help.
Working together allows weaker players to progress through higher difficulties while also contributing toward the Alliance’s requirements for unlocking higher-level Boss Challenges.
Rewards
There are two types of rewards available during the event:
- Personal Rewards
- Alliance Rewards
Personal Rewards
Personal Rewards are earned in two ways:
- For the First Kill of each Hell Nurse Level.
- For completing each difficulty.
Each difficulty contains 30 Hell Nurse Levels. Once all 30 Hell Nurses within a difficulty have been defeated, the Difficulty Clearance Rewards are awarded.

Alliance Rewards
Alliance Rewards are based on the successful clearance of each Boss Enemy difficulty by the Alliance collectively.
These rewards are given to all participants who took part in the corresponding Boss Challenge.

Summary
