Here's a chance for you to see if you actually want to buy Diablo IV. Not only is it 40% off on Steam and works great on Steam Deck and desktop Linux with Proton but it's also temporarily free to play.
Blizzard has made it free until Tuesday, 6PM UTC — so you've got quite a while to jump in and see what to expect from it. Once the free time is over though, you will lose access if you don't purchase it. And thanks to it being on Steam, for Steam Deck / Linux there's no special configuration needed and no messing around with manually installing Battle Net.
Something to note though, which Blizzard don't state on Steam, is that this free to play time only lasts until you hit level 20 in the game. Still a good few hours of gameplay though to give it a run.
With it being 40% off you can pick it up for £35.99 / $41.99 / €41.99.
Check it out on Steam.

You can see a previous Steam Deck video I did for Diablo IV below, although this was through Battle Net the performance is generally the same:
