Cosmetic sets are something that many Diablo Immortal players want to obtain. You can change the appearance of your character with cosmetic sets so that you can enjoy looking at it and playing with it, but they will not give you an advantage over other players. There are several ways to obtain cosmetic sets in Diablo Immortal, including battle passes, purchasing them from the shop, and participating in in-game activities. Diablo Immortal developers are aiming to release at least one set per month.
One of the best ways to get sets is to become an Immortal, which you can do with your clan. Free-to-play players are currently limited in the number of cosmetic sets they can obtain, but hopefully, in the future, they will add more ways to obtain cosmetic sets without spending money.
Cosmetic Sets from Battle pass
Every Diablo Immortal player is aware that there is a battle pass where you can obtain a variety of items that will aid your progression, but a battle pass also includes a Cosmetic Set. The issue is that in order to obtain sets, you must purchase a battle pass with real money, which means that free-to-play players will be unable to obtain them. Furthermore, each month a new battle pass with a new cosmetic set will be released.
In-game Shop
There is a section in the Diablo Immortal shop where you can purchase cosmetic sets with Orbs. The issue is that orbs can only be obtained by spending money within a game.
