[[Image:Quest-cow-king.jpg|frame]]You can open the red portal to the cow level as many times as you like, providing you don't get credit for killing the king. Credit is given if you kill him yourself, or he dies at the hand of another player who has never killed him before, while you are in the Cow Level. Being partied or not has no effect on the credit for the quest, it only matters who
kills the King.
* Kill the Cow King yourself. * Damage the Cow King in a game when someone else kills him to earn credit for killing him.
How the game assigns credit for killing the Cow King is tricky. See [http://forums.diabloii.net/showthread.php?t=341175 this forum thread] for the details.
If you've already killed the king or gotten credit for killing him when someone else did, you can't open the red portal anymore, but you can still enter the red portal when someone else opens it up.
