Diablo 2 alternative mode

Secret cow level, this is the only hidden mode under normal circumstances! I don't know the rest, if there is, it is also made of big boxes! ! I only know this one. ACT 1 There are five pillars in the quarry wilderness. After clicking, a red door will appear. You enter the red door, where Kane was saved. Look for it. There's a body. When you click, a lot of money will jump out. What you should pay attention to is not money, but white's leg. After defeating Barr, take him to ACT 1 and put him in that box, which is the synthetic gem. ! ! ! Besides, this book has to be filled with 20 volumes before it can return to the city. Click on the synthesis, a door will appear, and after entering it, it will be the secret cow checkpoint! ! As long as you don't kill cattle, you can go in and out again and again. If the cow is killed, it can only be entered once. ....
