In 2014, Diablo 3’s character artist Kevin Kanai Griffith passed away. To honor him, Blizzard implemented a bonus cow level named after him after his passing in the 2.4.0 patch, but there’s a caveat to the level. It can only be accessed in March, the month of Kevin’s birth. In addition to that level, the Kanai Cube item is also named after him.
As the video above shows, it’s not too much of a hassle to get to. To find the level and begin shortening the supply of milk all across the world, all you have to do is find the throne in Diablo 3’s new zone, the Ruins of Sescheron. Once you find it, you’re free to fight all the cows that you want, you monster. There’s even a mission called “Udder Cowlamity”, where you have to slaughter all the infernal bovines. Oh, cows. You can never be trusted, can you?
