Overview
Dolmen01 is a Valheim world location that spawns in the meadows and black forest biomes, identified internally as Dolmen01. World generation places up to 100 per world, with terrain constraints (max delta 2), and an exclusion radius of 8m, which is why some seeds have far more of them than others. The data tags it as randomly damaged and vegetation allowed.
