Guide
The Slime Serpent was a secret mount which was discovered during the Shadowlands expansion. To acquire the Slime Serpent mount, you will need to solo complete Plaguefall dungeon on either Heroic or Mythic difficulty from Shadowlands expansion.
IMPORTANT: Make sure you are not in party group when soloing the dungeon. Even if your party members are not in the dungeon, you will not be able to obtain a mount once you have cleared the dungeon.
Recommended level would be 70 equal to Dragonflight expansion. You could solo with lower level (for example 60), however, you will require very good gear and skill with your class to complete. Since you have to kill all the bosses in the dungeon, if you are level 70, you will hardly take any damage and kill the boss fairly quickly.
Note: Even though the mount is obtainable if you clear either Heroic or Mythic, it is recommended to do it on Heroic because the challenge of doing Mythic is unnecessary since the reward is the same on both difficulties.
For starters, take the portal to Shadowlands from Stormwind or Orgrimmar portal room respectively.
Once you are in Oribos, head to the second floor where you will use the flight master and fly to the Maldraxxus zone.
In the Maldraxxus zone, you will find the entrance of the Plaguefall where you will obtain the Slime Serpent mount.
IMPORTANT: Make sure before you enter the dungeon to set the dungeon difficulty to either Heroic or Mythic. The mount is not obtainable on Normal difficulty.
The dungeon Plaguefall has 4 bosses in total which you will need to kill to obtain the Slime Serpent mount. The road to the last boss is very straight forward. If you are doing this with level 70 character, you can skip most of the trash along the way since they are level 60.
Once you have cleared the last boss in the dungeon called “Margrave Stradama” you will be eligible to obtain the Slime Serpent mount.
When “Margrave Stradama” is defeated, turn around and go back to the 3rd boss room which is right above the last boss room.
To reach the 3rd boss room once again, turn around from the 4th boss room and head back into the tunnel from where you came from.
Make the first right, and you will see a transporter pad which you will use to reach the surface again.
Once you are back to the 3rd boss room, you will see in the slime river on the left side, friendly NPC called “Curious Slime Serpent“. Get close to the NPC and right click on it which will activate “petting“. Once the cast is complete, you will automatically receive the Slime Serpent mount!
