In the latest live broadcast, Blizzard announced that the upcoming season of "Diablo IV" will bring updates surpassing those of last year's second season, and players will have the opportunity to experience these new features early through the testing server.

Since the launch of the first season of the game, players have been urging Blizzard to add a PTR (Public Test Realm/Testing Server) similar to "Diablo III" and "Diablo II: Resurrected". The significant issues that arose after the release of the third season once again demonstrated the importance of a testing server, and Blizzard appears to acknowledge this.

However, Blizzard explained during the live broadcast that not every season will have a testing server. Community Deputy Director Adam Flecher stated, "This depends on the scale of the changes we make, but for the fourth season, we absolutely plan to open the PTR." Subsequently, developers mentioned that the testing server launch date and the content of the fourth season will be announced in another live broadcast "several weeks later".

Blizzard has not yet disclosed the specific content of the fourth season, but it promises to make significant and fundamental changes to the equipment drop mechanism. Currently, only a small amount of equipment dropped is worth keeping, and most will be converted into materials, requiring players to spend a considerable amount of time reviewing equipment values.

In a previous broadcast, Blizzard stated that the goal of the fourth season is to make dropped equipment more valuable, regardless of whether it is better than the player's current equipment. This is likely to be a transformation system similar to other ARPGs like "Path of Exile".

The new broadcast also revealed significant changes to the summoning creatures of the necromancer in the fourth season, with summoned skeletons and other minions possibly becoming stronger as the character levels up, similar to the mechanical spider minions in the third season. Adam Jackson, Chief Designer of Real-Time Services, stated, "Making minions feel better is one of our top priorities. In addition to the patch in the middle of next week's season, we also plan to introduce a lot of content in the fourth season."
