If you’ve just logged into Creatures of Sonaria and noticed a massive new three-headed creature roaming around, you’re not alone. The LSS Week 4 update introduces Mirageon, alongside new event missions, creature redesigns, subspecies, and a few redeem codes.
The game doesn’t exactly explain everything clearly, so if you’re wondering how to unlock Mirageon, where to find the event objectives, or what you should actually be doing first, here’s a simple walkthrough.
How to Unlock Mirageon in Creatures of Sonaria
Mirageon is one of the headline rewards in the LSS Week 4 event.
To start progressing toward unlocking it:
- Open the LSS Event menu.
- Select Missions.
- Complete the available event mission chains.
- Earn the required event progress until Mirageon becomes claimable.
The update adds multiple mission categories, so you’ll need to complete objectives instead of simply collecting a creature through the shop.
Corrupted Cleanup Mission Guide
One of the main mission chains is Corrupted Cleanup.
You’ll need to complete these objectives:
- Destroy 10 Corrupted Growths
- Defeat 10 Corrupted NPCs
- Collect Corrupted Shroom Piles
Thankfully, none of these objectives are especially difficult once you know where to look.
Destroy Corrupted Growths
These corrupted plants appear around the event map.
Simply attack them until they’re destroyed. They count toward your mission progress immediately.
Defeat Corrupted NPCs
Corrupted enemies spawn throughout the event areas.
Defeat a total of 10 of them to complete this part of the mission.
If you’re using a weaker creature, don’t rush into fights. Some event enemies can deal surprisingly high damage.
Collect Corrupted Shroom Piles
This objective confuses many players at first.
The Corrupted Shroom Piles are scattered across the ground throughout the event area.
Instead of fighting for them, spend a few minutes exploring the map carefully.
One thing to remember: other players can attack you while you’re collecting them, so stay alert if you’re carrying valuable progress.
Purification Efforts Mission Explained
Another event mission is called Purification Efforts.
Its main objective is simple:
- Contribute 1,000 Shrooms to a Purification Spire
Once you’ve donated enough Shrooms, the mission progresses automatically.
If you’ve been saving Shrooms, this is one of the easiest objectives in the event.
Best Way to Finish the Event Faster
After spending some time with the update, a few strategies make the grind much smoother.
Explore Before Fighting
Many objectives require collecting items rather than defeating creatures.
Running around the map first can save a lot of time.
Avoid Unnecessary PvP
The event zones often become crowded.
If another player starts attacking, it’s usually better to escape instead of risking losing progress.
Use a Durable Creature
Some corrupted enemies can hit surprisingly hard.
Tankier creatures survive much longer while completing objectives.
Finish Every Mission Together
Rather than focusing on one objective at a time, collect Shroom Piles, defeat NPCs, and destroy Corrupted Growths during the same trip around the map.
It makes progression feel much faster.
Mirageon Stats Overview
Mirageon is one of the largest additions in this update.
Some of its revealed stats include:
- Health: Approximately 3,000
- Damage: 265
- Stamina: 120
- Growth Time: 40 minutes
- Weight: Around 33,000 lbs
It’s clearly designed as a heavyweight creature and fits the “giant beast” role very well.
Other Features Added in the Update
Mirageon isn’t the only thing added this week.
The update also includes:
New Creature Redesigns
Several existing creatures received visual updates, including Sarchias and other older favorites.
Some of these redesigns also come with updated stats.
New Subspecies
Additional subspecies have been introduced, giving players more customization options for certain creatures.
If you enjoy collecting different variants, it’s worth checking every creature you already own.
LSS Week 4 Event
The event has a limited duration, so make sure you complete the missions before it ends.
Waiting until the last day could make unlocking Mirageon much harder.
Working Creatures of Sonaria Codes
According to the update, these codes are currently available:
- COSYEAR5
- DIS25
- COSBILLION
- CAMPFIRECAMPOUT
- AMBEREXTRAVAGANZA
- 2025CAMPFIRE10
Redeem them through the game’s code redemption menu to claim any available rewards.
As always, codes can expire without notice, so it’s worth redeeming them sooner rather than later.
