What you actually need
- Complete the relevant difficulty: Diablo in Classic without the expansion, Baal in Lord of Destruction.
- Have the Horadric Cube, Wirt’s Leg and a Tome of Town Portal. A single Town Portal scroll is not the required tome.
- Transmute in Act I’s Rogue Encampment. The ingredients are consumed to create the new access.
Step by step
Choose difficulty
Create a new game in the completed difficulty. Take the Stony Field waypoint and enter Tristram through the stones.
Collect Wirt’s Leg
Click Wirt’s corpse in northwestern Tristram and pick up the leg. Use the ingredient from the appropriate difficulty.
Prepare the tome
Buy a separate Tome of Town Portal from Akara if you want to keep your regular travel tome. It need not contain twenty scrolls.
Create the red portal
In the Rogue Encampment, put the leg and tome in the Cube and transmute. The red portal leads to the Moo Moo Farm.
Original game: the Cow King quest can lock access
In original Diablo II/LoD, completing the hidden Cow King quest can prevent the same character from opening further cow portals on that difficulty. The exact group rule depends on the king killer’s quest status and the characters present; it is not simply about your own hero landing the final hit.
To preserve your own recipe access in the original, keep yourself and uncontrolled minions away from the king and establish the group’s intention beforehand. Resurrected removed this portal lock; this warning is not a D2R rule.
A practical first cow run
Keep the entry clear. Pull one small pack into your area damage rather than dragging more enemies across the entire map. A second Town Portal in a safe spot provides a sensible retreat if the red entry gets blocked.
Plan around your target: runes and useful equipment bases call for different loot evaluation from hunting uniques. More cow kills provide more loot attempts; that does not establish a fixed reward after an invented total.
