Blizzard has released patch 2.7.3 for Diablo 3 which features the long-awaited season 26, as well as the new activity Echoing Nightmares.
Echoing Nightmare is the first activity to be added to the game and takes the form of a challenge event that will make players test their abilities in a series of trials in order to “stay in the fight as long as possible”. As usual, a new season means new rewards, but this time the developer is making it so awards originally available from season 14 are returning for players who missed out along the way.
