i cant find the infernal hive in the nether how can i easy see its one
In my experience all you can do is dig and dig a lot. Conversely some biomes in the overworld appear to spawn a few Infernal hives and Oblivion hives. Infernals in the overworld will be encased in glowstone and Oblivion will be encased in Endstone.
but where do i find it often in the nether? like is it together with quartz ardite or cobalt and have you ever found one and if you where in the nether?
It's a random pattern, there is no way to expedite the process of finding a hive that I have seen. All you can do is dig a lot and hope you will find one (or be lucky enough to find one on the surface).
