Diablo 4 Halloween Event Offers Unique Rewards For a Limited Time

A new Diablo 4 event is now available, having launched with a Halloween theme and an offer of unique rewards. The ongoing promotion is part of Diablo 4 's Season 15. The Halloween event arrived alongside Diablo 4 's October 28 update , which introduced several notable changes to the hit hack-and-slash RPG. Among other things, the patch increased the maximum Prime Evil Splinter stack size from one to 99, addressing a recurring inventory-management complaint from Season 15 players.
