Overview
SwampRuin2 is a Valheim world location that spawns in the swamp biome, identified internally as SwampRuin2. World generation places up to 50 per world, with terrain constraints (min altitude 0), and an exclusion radius of 10m, which is why some seeds have far more of them than others. The data tags it as randomly damaged.
