Diablo creator David Brevik explains his original version of Diablo 3 which was very similar to the current Diablo 4.
Petrified Scream in Diablo 3 was first introduced in season 26. This special resource is mainly used to get access to the Echoing Nightmare.
Challenge Rifts in Diablo 3, a significant aspect of the title, are based on Greater Rifts that players have completed in the game in the past.
