The Diablo IV Server Slam was fun! The most exciting part for me was fighting Ashava the Pestilent with a random group of (approximately) eight or nine other players. The screenshot above shows that our group managed to kill Ashava. The reward for doing so will appear in Diablo IV after it launches.
To make this short video of clips, I went through the video clips that my Xbox recorded for me during the Server Slam. There are no spoilers in this video.
