Diablo 4's adding a wave-based roguelite mode in Season 5
Diablo 4's fifth season will have an interesting-sounding new mode—an activity called Infernal Hordes that's something like a roguelite. Using an item called in Infernal Compass, players will be able to enter the Realm of Hatred and fight timed waves of enemies. Those enemies will drop burning aether, and between waves you'll be able to choose «Boons & Banes» that let you get more aether.
