The Serpent in Valheim: The Ocean's Only Hostile, and It Is Immune to Fire
The Ocean is Valheim's emptiest biome by design. The Serpent is currently the only hostile creature that spawns there — one enemy for an entire third of the map. It has 400 health, is immune to Fire, Spirit and stagger, resistant to Poison, and weak only to Frost, which is an awkward combination when you are fighting it from a wooden boat.

The Numbers
| Field | Value |
|---|---|
| Location | Ocean |
| Faction | Sea |
| Health | 400 |
| Weak to | Frost |
| Resistant to | Poison |
| Immune to | Fire, Spirit, Stagger |
| Attack | 70 Slash |
| Drops | Serpent meat, Serpent scale, Serpent trophy |
Fire immunity is the entry that catches people out. Fire Arrows are the standard ranged upgrade through the Black Forest and the Swamp, and against a Serpent they contribute only their Pierce half — the fire component does nothing at all.
Stagger immunity removes the interrupt, which matters more at sea than on land: you cannot knock a Serpent back to buy yourself distance while your ship turns.
Frost is the single answer, and it is a convenient one, since Frost Arrows and frost weapons are available around the same time most players start making long ocean crossings.
Fighting From a Boat
Its attack is a straightforward 70 Slash bite, which is survivable for a geared player and lethal to a boat you are standing on. The tactical problem is not the damage — it is the venue.
- Fight it from the deck with a bow. Frost Arrows exploit its only weakness, and staying aboard is the entire plan.
- Do not expect to stagger it. Immune. There is no moment where it stops.
- Do not use fire. Immune. Fire Arrows lose their fire half entirely.
- Poison is resisted as well, so poison arrows are also a poor pick.
- Keep moving. A Serpent pursuing a moving ship is easier to shoot than one circling a stationary one.
Serpents are hunted rather than avoided by most players who have made a Karve or better, because their drops are worth the fight.
What It Drops
| Drop | Use |
|---|---|
| Serpent meat | Serpent stew — the highest-health food in the Swamp tier at 80 |
| Serpent scale | Serpent scale shield |
| Serpent trophy | Decoration |
Serpent stew at 80 health is the reason. It is the best health food available around the Swamp, ahead of Sausages at 55, and Serpent meat is its gating ingredient. A single Serpent supplies several servings.
The Serpent scale shield is the other reason: a shield made from a creature you can only meet at sea, which most players do not build simply because they never fight enough Serpents.
The Ocean Is Otherwise Empty
The wiki is explicit that the Serpent is currently the only hostile creature spawning in Oceans. That single fact shapes how you should treat sea travel:
- The ocean is not dangerous in the way a biome is. There is exactly one thing out there that will attack you, and it has 400 health and one attack.
- What actually sinks ships is weather, not creatures — wave height and wind, which are their own system.
- A serpent encounter is optional. They can be outrun by a Longship in reasonable conditions, so every Serpent fight is a fight you chose.
That last point is worth taking seriously. If you do not want the meat or the scales, sail on. The only reason to engage is that Serpent stew is genuinely the best food of its tier, and the scales build a shield you cannot get anywhere else.
Running your own Valheim server
Long ocean crossings are the part of Valheim that spans sessions, and a crossing only makes sense on a world that is still there when you log back in. A gamever Valheim server keeps it persistent for up to 10 players, with one-click backups.
Conclusion
The Serpent is the only hostile creature that spawns in Valheim's Oceans, which makes an entire biome's threat list one entry. It has 400 health, bites for 70 Slash, and its defensive profile is the fight: immune to Fire, Spirit and stagger, resistant to Poison, and weak only to Frost. Fire immunity is the trap, because Fire Arrows are the standard ranged upgrade by the time most players reach open water and their fire component does nothing here; Frost Arrows are the correct answer, and stagger immunity means there is never a moment to press. The right venue is the deck of a moving ship with a bow, since the bite is survivable and the boat is not. Its drops justify the detour: Serpent meat makes Serpent stew at 80 health, the strongest food of its tier and well ahead of Sausages at 55, while Serpent scale builds a shield with no alternative source. And because a Longship can outrun one in reasonable conditions, every Serpent fight is one you chose to have.
