However, if you do not kill Baal (or Diablo, if you don't have the expansion) on that difficulty you will be unable to make the red portal, but you will never get credit for the quest to kill the Cow King (because you need to have killed Baal/Diablo to be able to start the quest). Watch your Mercenary and Summons as they can 'accidentally' kill him, too. If you don't want to complete the Cow King quest or are unsure, the safest place to be is in town (use Town Portal scroll!).

The area that is corrupted is shared between Hardcore/Softcore, Regions, and Ladder/non-Ladder.If anyone kills Cow King for FIRST time (except, a person who has NOT killed Baal/Diablo, see below), then everyone INSIDE the Cow Level will get credit for the (hidden) Cow King quest and will NOT make the red portal anymore.
