Along with this repeat visit ability, the cows were greatly increased in damage, experience value, and item dropping capability. That changed in the Diablo II Expansion, when characters were able to enter the level repeatedly, so long as they did not get credit for completing the quest by killing the Cow King. It wasn't very rewarding, other than in laughs. The level was amusing, but only a diversion in Diablo 2 Classic, since it could only be entered once per character/per difficulty level. (See the Secret Cow Level page in the Diablo 2 section of this wiki for full details.) The Blizzard North guys were inspired by this to work up a full sized level of walking, mooing, halberd-wielding cows, and the Secret Cow Level was born. The Secret Cow Level is an Easter Egg a funny bonus area in Diablo II that played on years of jokes about a secret level that could (supposedly) be reached in Diablo, by repeatedly clicking the cows found just outside of town.
