Diablo 4 is being operated as a live service. This means that the game will require ongoing monetisation to fund updates during its life cycle.
No Pay to Win
Blizzard has made it clear that items purchasable in the Diablo 4 short will provide no power advantage to player. Items available in the shop are purely cosmetic.
Blizzard explained in their August 2022 developer update:.
The way we approached designing the Shop and the cosmetics within it was by thinking about the experience we want players to have. We want buying things to feel good–before, during, and after purchase. So, if players choose to buy something, it should be because they want to, not because they feel like they have to. It should also be clear to players exactly what they are getting before they choose to buy, with no unpleasant surprises.
The Shop’s cosmetics build on top of the foundation of a huge variety of transmogs from weapons and armors players will find in-game. It’s also important to us that the Shop is grounded within Diablo’s world, so our cosmetics are holistic fantasies, the individual components of which can be mixed and matched with transmogs from armors acquired in-game for endless customization options.
The Shop sells cosmetics for Premium Currency. Cosmetics give players even more options to customize the visual appearance of their characters. Nothing offered in the Shop grants a direct or indirect gameplay advantage. So, while many of these may look like powerful pieces of gear, they have no in-game stats.
Optional Cosmetics and Transmogs
All items are optional and players are not required to use the shop if they don't want to.
Blizzard has stressed that cosmemtics in the shop will not necessarily be the best looking cosmetics in the game thanks to the Transmog system which allows players to customise their look by changing the look of items.
These Transmogs will be unlockable from drops in the game.
There are incredible pieces—Unique and Legendary quality items—for players to find without ever going to the Shop. The Shop offers more diversity of choices, not systematically better choices.
Restricting Shop Transmogs
All armor Transmogs in the Diablo 4 Shop are restriced to the class they were designed for. Blizzard describes them as "class-specific fantasies".
Cosmetic Armor Examples
Blow are examples of the types of armor changes players can find in the DIablo 4 shop for their class.
Previewing Before Buying
Players can preview their their purchases on their character prior to buying the item in the shop. See below shot.
Can you sell Shop items to other players?
No. Blizzard has confirmed that everything that is purchased in the shop is accoun-bound and cannot be sold to another player.
