Players who own the Vessel of Hatred expansion can boost a second character this way.While Blizzard refers to the Welcome Back Booster as a limited-time offering, there is no end date listed in their blog.Return of the Red-Cloaked Horror From Tuesday, Nov. 19, to Tuesday, Dec. 3, the Red-Cloaked Horror monster has a chance to spawn instead of a Hellborne in Helltide. It can also spawn randomly in dungeons and the Infernal Hordes mode.The Red-Cloaked Horror can drop a variety of rewards, including the event-exclusive Gideons Brew, which is a powerful Elixir that increases damage done, XP earned, and materials acquired for 30 minutes.Limited time Spiritborn trialFrom Tuesday, Nov. 19, to Monday, Dec. 2, players who dont own the Vessel of Hatred expansion can jump in and make a Spiritborn Diablo 4s sixth character class. While the trial will only be available to level up to level 25, character progress will carry over for those that eventually pick up the expansion.If this is your first time trying the class, see our best Spiritborn build guide.Mothers Blessing XP boostFrom Tuesday, Nov. 19, to Tuesday, Nov. 26, the Mothers Blessing XP and gold boost will return to Diablo 4.
