In Season 2, the Wanderer, a fanged danger, appears out of nowhere. The Diablo IV development team announced that the Season of Blood would commence on October 17 during Gamescom.
A freshly transformed army of bloodthirsty vampires has targeted Sanctuary under the command of their evil leader. While the master’s evil scheme remains a secret, their pursuit of the blood of innocents has sparked significant controversy. Your fate hinges on your ability to hunt the hunter.
The Season of Blood will include a new questline, vampire powers that you can use against their creators, 5 new endgame enemies capable of dropping certain Unique and Uber Unique items, and more.

In addition to the above, Season of Blood will introduce certain quality-of-life changes that the community has requested:
• More effective gem inventory management.
• Once earned with an Eternal or previous Seasonal Realm character, Paragon Points, Skill Points, Potion Charges, and Obol capacity increases will carry over into a new Season.
• Modifications to the way status effects like Elemental Resistances, Overpower, Critical Strike Damage, and Vulnerable operate.
Both the Seasonal and Eternal Realms will have access to the changes mentioned in the bullet points above, as well as the option to target specific Unique and Ultra Unique drops.
