Blizzard Entertainment has announced another public Beta for Diablo IV, lovingly dubbed the Server Slam event.

The new Diablo IV Server Slam Beta will run from May 12th to May 14th, and will feature bug and balance fixes based on feedback from the previous betas.

This build will be available for PC, Xbox One, Xbox Series X|S, PS5 and PS4 and will also allow you to play couch co-op with your friends.

Progress from previous betas will not carry over into the Server Slam, though awards earned during both this beta or the previous ones will carry over into the full game when it launches.

It will also feature a boss you’ll be able to fight, Ashava:

Steel yourself before one of the Burning Hells’ most fowl machinations, Ashava. She’s a lumbering behemoth with two razor-sharp arm blades, scales stronger than plate mail, and hell-bent on ripping through all who interrupt her quest to bathe Sanctuary in poisonous bile.

Because your characters can’t surpass Level 20 during Server Slam, felling her will be quite the monumental task.

Here’s when you’ll have an opportunity to combat Ashava during Server Slam:

May 13 starting at 9 a.m. PDT and every 3 hours thereafter until the final spawn on May 14 at 9 a.m. PDT.
