Everything above walks in from outside the event radius, so a wall and a raised platform matter more than raw damage: the spawns path toward you and a stake wall buys the time to shoot them.

A foul smell from the swamp... is a Valheim raid unlocked by Bonemass and lasting 2 min. It sends Blob, Oozer and can fire in Plains, Meadows, Swamp, Black Forest. It stops being possible once — the game keeps a key for that and quietly drops the raid from the pool rather than announcing it.

A foul smell from the swamp... FAQ

What unlocks A foul smell from the swamp...?

Bonemass. The game records that as a world key, and the raid joins the pool from then on.

How long does A foul smell from the swamp... last?

2 min. It can fire in Plains, Meadows, Swamp, Black Forest, and everything it sends walks in from outside the event radius rather than appearing on top of you.

What triggers A foul smell from the swamp...?

It becomes possible Bonemass. Until then the game will not roll it at all, which is why a raid that "never happens" is usually a raid that has not been unlocked yet rather than bad luck.

What attacks during A foul smell from the swamp...?

Blob, Oozer. The spawns are fixed rather than scaled to your gear, so the answer is the same on day five and day five hundred; what changes is whether you can hold the wall.

How do you survive A foul smell from the swamp...?

Raids target structures within 96 metres of you, and they spawn outside your base rather than inside it. A wall with no gap at ground level, a raised earth bank, and somewhere to shoot from turns almost every raid into a queue. Fighting in the open is what makes them dangerous.
