The Kraken sea turtles or Leviathan or Floating Islands however you want to call them the name Kraken for these big island-like creatures might be confusing for some as most of us know Kraken as large octopus-like creatures but in the earliest descriptions in Norse mythology dragons were actually more crap-like creatures.
These are the name leviathan for them comes from the game files as that’s what these are referred as in them and some of us just call these sea turtles to call them leviathans because that’s what the game calls them on their back groves abused barnacles which can be mined for cheating when farming alone usually get about 20 cheating bear leviathan before need to save me the leviathan will submerge when you have mined enough.
It’s otherwise non-hostile make sure you are aware of the position of your ship when mining so when the leviathan submerges you don’t accidentally drown currently cheating is only used to make avocado razor and the abyssal harpoon with level 4 workbench abyssal harpoon you use to hook serpents and drag them to shore to get 7 scales because if even one part of the valheim serpent touches water it doesn’t drop serpent scales and abusal razor is the second-best knife currently in the game.
