- Start by heading to Byalan Dungeon (Level 5). Make your way to the top center of the map and you will see Nobby the Novice (Located at 114, 248).
- Speak to Nobby and ask him what's wrong. After some dialogue, he will let you warp into the Kraken's Lair instance. Some information about the instance includes:
- Note: If there are people that are not online in your party when you attempt to start the instance, you will be stuck on a dialogue box and will have to wait for the cooldown to finish before you can enter again.
- After entering the instance, kill any and all monsters you encounter. There is a chance to obtain quest pieces which can be used later on.
- Head up the stairs to the right, and speak to the Corpse.
- From there, head back down the stairs and off to the east. Cross the bridge, and speak to the algae (Located at 238, 217). After that, you will obtain a key.
- A bit more to the NorthEast, you will see a Door. Click on it, and type in "Atlanture". Click the door again to be teleported through it to the first area.
- This area has 13 bubbles to deactivate. Which when clicked will open up a "Door".
Not much information is known about this area except that by completing it, you obtain a key. This would make 2 keys obtained so far.
- Make your way around the area and speak to Nobby to carry on to the next area.
- First thing you will see in this area is Nobby, just sitting there in the middle. If you have not collected any of the items mentioned before from killing the monsters, you can speak to him here and purchase the items for 10m zeny each.
- Head a little north, and you will see a barracks.
- Throughout this area, scattered with the monsters, are weapon like monsters, which you must kill all 6 to obtain another key. This makes 3 keys obtained so far.
- When finished, head up the large staircase and as long as you have those 4 monster pieces you were told about earlier (Either from killing monsters, or buying them), you will be able to speak to the Altar and head to the next area. By placing all 4 pieces into the altar, you will obtain another key. This makes 4 keys obtained so far.
- This is the final area. Scattered around are 4 sets of Two "Tentacle Appendage". Kill all 8 of them, and the final 2 Appendages next to the Kraken will become mortal.
- Locate the Kraken in the lower right corner and kill him. After killed, you will receive another key. This makes 5 keys total.
- Make your way to the center platform, and a chest will appear. Depending on the keys you have obtained throughout the instance, you will have access to different rewards. Which key relates to which reward is currently unknown. The types of rewards include:
- 40,000,000 Zeny (Not always required)
