Troll Cave — Valheim Location
Troll Cave world-generation rules in Valheim 1.0: how many copies a world places, the biome and altitude it needs, its spacing and footprint, and how far the nearest copy sits from spawn.
Cave Black Forest Verified 1.0
If the name comes up struck through, this world has no room for it — type your own seed and the map looks again.
Nearest copy over 600 sampled worlds generated by our world map: closest seen 505 m, typical 763 m, and in 9 worlds out of 10 within 805 m — straight-line from the spawn area.
How it generates
| Prefab | Per world | Biome area | Altitude | Min spacing | Footprint |
|---|---|---|---|---|---|
| TrollCave02 | 200 | Median in forest only | above 3 m | ≥ 256 m | 12 m radius |
- Biome area — “Median” means the zone and all eight of its neighbours must share the biome, so it never generates on a biome border; “Everything” may place anywhere inside the biome.
- Footprint is the exclusion radius the generator keeps clear around the piece, not the size of the structure you walk into.
- Per world counts placement attempts, so a number here is an upper bound — terrain checks decide how many actually land (see the sampled-worlds figures above). unique is a separate flag: the table checks it once before placement begins, to skip re-rolling these on a world that already exists, and it does not cap the attempts a fresh world makes.
- Terrain tolerance — the generator allows up to 10 m of height change across the footprint, with a minimum of 5 m .

The interactive map generates your world from its seed and marks every one of these, or use the seed finder to search for a world that places them the way you want.
Common questions
- How many "Troll Cave" does one Valheim world place?
- A fresh world makes 200 placement attempts for Troll Cave.
- Where does Troll Cave spawn?
- Troll Cave generates in Black Forest, under the “Median” rule — the zone and all eight of its neighbours must share the biome, and only inside a forest area. Altitude: above 3 m.
- How far is the nearest Troll Cave from spawn?
- Measured over 600 sampled worlds, the closest copy was 505 m from the spawn area, the typical distance was 763 m, and in 9 worlds out of 10 it sat within 805 m. All distances are straight-line.
- How much space does Troll Cave need to generate?
- The generator keeps a 12 m exclusion radius clear around each placement and requires at least 256 m to the nearest similar placement, with terrain varying by no more than 10 m across the footprint. The exclusion radius is clearance the terrain must offer, not the size of the structure you walk into.
