Trying to find and fight him but the wiki says his vegvisir is extremely rare and its usually easier to just find his alter?? Ive explored 4 different plains biomes and havent come across a stonehenge or his alter. Is there certain areas he may be more likely to be in? Like say closer to the edge of the map or by certain other biomes or something? Im honestly starting to get a little frustrated lol (I hate the plains biome and want to be done with it already lmao).
