Urchin Fields are dangerous anomalies found in every biome except Bunkers. They are categorized by a low to high pitched droning noise surrounding floating objects resembling sea urchins. These objects are harmless at a distance but if the player approaches too close, the urchins will rapidly expand and deal damage to the player. They will stay enlarged until the player leaves the immediate area. It should be noted these objects do not deal a whole lot of damage at once, however they are clustered together very closely and in large numbers. It is advised you wear mid-tier clothing should you artifact hunt in an urchin field. As with Orb Fields, and Holy Ghost Fields, Urchin Fields will spawn in multiple points across the map in large clusters.
Artifacts are capable of spawning inside Urchin Fields.
