If you want to keep the sea serpent in place when hunting it, you will need to make an item called a harpoon; here's how and what you need.
How to make an Abyssal Harpoon in Valheim
To make a harpoon in Valheim, you will need the following materials and a level two workbench.
- Eight Fine Wood
- 30 Chitin
- Three Leather Scraps
Once you got all of that, you can then make an Abyssal Harpoon, and it will have the following stats shown in the image below.
Overall a harpoon has some weak stats, but this is alright because you are not meant to use it as a primary weapon; you see, harpoons are intended to keep targets in place while you switch to a better weapon, such as a dragur bow.
Harpoons are also excellent when hunting sea serpents in the open ocean biomes, as keeping these monsters in place without one is a tricky task. That said, we recommend making a harpoon if you intend to go after sea monsters or if you want to try it on a boss.
However, suppose you have trouble using a harpoon on the sea monster. In that case, we recommend instead using a dragur bow we previously mentioned, along with some frost arrows. Both combined will effectively keep the sea monster in place just as good as a harpoon, if not even better. That being said, if you don't know how to craft either item, here's how below.
