In Diablo 2 Resurrected, the Vipermagi's skin is a unique set of armor, with +1 to all skills, +30% faster cast rate, and +all resistances, this armor will improve both your damage output and survivability. But in the game, it is randomly dropped, so we cannot guarantee that we can get it 100%.
However, MMOSO will list some places where the drop rate of Vipermagi's skin is higher. If you like this exploration process, then you can go to the following places to explore. If you can't wait to get it, then the fastest way to Buy D2R Items is from MMOSO.
On Normal difficulty, you are most likely to get a Vipermagi's skin in Baal. The same applies to the end of act bosses in Nightmare and Hell difficulty.
Secret Cow Level
If you don't want to spend too much time on the farm boss, then another better option is the Secret Cow Level on Nightmare difficulty. You can go to the Forgotten Tower and the Rogue Monastery (especially its prison) on Nightmare difficulty. Both are in Act 1. You may get Vipermagi skin in the late stage of Nightmare.
The first place where Vipermagi's skin drops is the Crystalline Passage in ACT 5 of Normal Difficulty, but the chance of finding it is less than one in three million, so we don’t need to spend too much time there.
The above are the three locations where you can get Vipermagi skin introduced by MMOSO. If you don't get the Vipermagi skin in these locations, you can come to MMOSO to buy the suit, and Buy Diablo 2 Resurrected Items will be available for sale at any time. You can buy what you want with a small amount of money.
