The Secret Cow Level is a Terror offer, not an act of the campaign. Carry Wirt's Leg and any Terror offer may be the Cow Level instead of an act: three minutes of 
Hell Bovines at the tier's level and with its affixes, with 
The Cow King arriving at the one-minute mark.

Getting the leg
Griswold drops Wirt's Leg. He arrives in Act I at 4:45.- Carry the leg. While one waits in your stash, Griswold drops no second one.
- The leg can be dropped from the stash or Charsi's window if you want it gone.
In the level
- The herd comes at the Terror tier's monster level and affixes, so a tier-10 Cow Level is as hard as a tier-10 act.
- It gets trippier every two minutes: the colours shift. Item names on the floor keep their colours, so rares stay yellow and magic items blue.
- The automap shows no shrines from the act you left.
