How many "Ruin" does one Valheim world place?

Ruin is placed by 3 separate generator rules — Ruin1: 200 placement attempts; Ruin2: 200 placement attempts; Ruin3: 50 placement attempts.

Where does Ruin spawn?

Ruin generates in Black Forest and Plains, under the “Everything” rule — it may place anywhere inside the biome. Altitude: above 1 m.

How far is the nearest Ruin from spawn?

Measured over 600 sampled worlds, the closest copy was 501 m from the spawn area, the typical distance was 583 m, and in 9 worlds out of 10 it sat within 683 m. All distances are straight-line.

How much space does Ruin need to generate?

The generator keeps a 10.7 m exclusion radius clear around each placement and requires at least 512 m to the nearest similar placement, with terrain varying by no more than 3 m across the footprint. The exclusion radius is clearance the terrain must offer, not the size of the structure you walk into.

How it generates

Prefab	Per world	Biome area	Altitude	Min spacing	Footprint
Ruin1	200	Everything	above 1 m	—	10.7 m radius
Ruin2	200	Everything	above 1 m	—	9.89 m radius
Ruin3	50	Everything	above 1 m	≥ 512 m	10 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 3 / 3 / 3 m of height change across the footprint (no minimum) .
