Stage 4: Special Lab
- If you have managed to obtain a Romeo's Letter or Juliet's Letter in Stage 1, give the letter to the respective NPC.
- Kill the Neo Huroid in this map until it drops a Card Key. The Card Key is used to open the doors on the left and right side of the map - the left door is for the Thief with maxed Haste or a character with 120% Jump, while the right door is for the Magician with maxed Teleport, both of which consist of jump quests of sorts in a darkened area as in Stage 2.
- It is recommended to be ready with a Card Key when a character is ready to enter or exit the respective door - the rooms behind both doors deplete a character of 100 HP every 3 seconds.
- At the left room, the character needs to go towards the top platforms and hit the boxes to look for Alcadno's Experiment Files - potions and mesos may drop instead. At the room on the right, the Magician should teleport around to locate Zenumist's Experiment Files in the boxes.
- It is also recommended that one player is sent to either room at a time. When the player is ready to exit it, other players outside the room should be ready with a Card Key to ensure that the player is out quickly.
- Hand over both files to the NPC and proceed through the door to the next stage.
