Overview
StoneTowerRuins09 is a Valheim world location that spawns in the black forest biome, identified internally as StoneTowerRuins09. World generation places up to 80 per world, with terrain constraints (min altitude 2, max delta 2), and an exclusion radius of 7m, which is why some seeds have far more of them than others. The data tags it as randomly damaged.
