While the event is active, world bosses encounters will change the environment. Get ready to face a terror-inducing blood rain!
The event begins on October 23, 2025 and ends on November 6, 2025.
Of course, an environment change isn't the only thing, as there will also be new loot to earn. If you take down these world bosses, they have a chance to drop two new Legendary pieces of gear.
Murmur - a Tediore Assault Rifle that executes weakened enemies with guaranteed crits on enemies below 35% health.
Skully - an Order Grenade that fires out projectiles as it seeks out a target.
SHiFT codes will be given out during this event, granting the Gourd Your Loins (pumpkin) Head for all Vault Hunters, along with the Hex Appeal weapon skin.
