The Cow King is the Super Unique boss of The
Secret Cow Level. It looks just like any other
Hell Bovine: there aren't any visual clues to identify it, except highlighting. However,
The Cow King always spawns inside the fenced enclosure located in the
Secret Cow Level, so players who wish to
avoid killing him can just avoid the enclosure altogether.
In Diablo 2 Resurrected, it is confirmed that killing
The Cow King no longer prevents future portal openings with the same character!
