Portal to Tristram can (still) be found at Cairn Stones in Stony Field after completing the Search for Cain in Act 1.
Wirt's body can be found in west corner of Tristram, close to river. Click on it and Wirt's Leg and gold
are dropped. Leg requires 1x3 inventory space to pick up, and it can only be picked up if one is not already equipped or present in inventory or stash.
After completing difficulty level by killing Diablo in Classic and Baal in Expansion, return to Rogue Encampment in Act 1 with Wirt's Leg and place it in Horadric Cube with Tome of Town Portal, which can be bought from Akara. Transmute anywhere in Rogue Encampment to create portal to Moo Moo Farm.
Portal created while standing just inside Rogue Encampment may actually be created just outside in Blood Moor
, resulting in it being labelled No Level Name rather than The Secret Cow Level. Despite this, it still leads to Moo Moo Farm.
- The Cow King drops eight Stamina Potions upon death (among other things) but, while this completes quest, players aim to kill everything in Moo Moo Farm except The Cow King, since this prevents them from creating another portal to access area again (even when they do not kill him themselves: quest is completed for all players present in area when anybody kills him who has not done so in an earlier game).
- Although not every item can drop, the size of groups, monster density, openness and lack of immunity make area popular due to high number of drops possible in short period of time.
- Players who have already completed quest can still access area via portal created by player who has not (they may also collect another Wirt's Leg, even though they can't create portal with it).
- Players who have already killed him can do so again without completing quest for other players in area.
- Best for creators of portal to never enter it, ensuring there is no chance of them losing this ability.
- The Cow King is Immune to Lightning in all difficulty levels, so characters specialising in Lightning Damage are recommended for clearing level with little to no risk of killing him (Amazons with Lightning Fury and Sorceresses with Lightning Spells are popular choices; Assassins with Lightning Sentry or Claws of Thunder and Paladins with Holy Shock are other possibilities).
- Only Hell Bovines can drop Cow King's Leathers:
