Overview
TarPit2 is a Valheim world location that spawns in the plains biome, identified internally as TarPit2. World generation places up to 100 per world, with terrain constraints (max delta 1.5, altitude 5-60), and an exclusion radius of 25m, which is why some seeds have far more of them than others. The data tags it as randomly damaged.
About
TarPit2 is a Tar pit variant in the Plains. Growths emerge from the dark puddles when disturbed, and the pit yields Tar when mined.
