The Helltides.com World Boss Timer for Diablo 4 lets you know when and where a World Boss is about to spawn. Click the 🔔 on the timer pane to enable browser notifications, and adjust the audio notification by clicking the 🔊 and using the volume slider.

Customize the timer and choose custom audio alerts by clicking the ⚙️ at the top of the page. Users can set a timer to be alerted when the World Boss spawns, or 1, 5, 15, 30, or 60 minutes before it spawns. Never miss another World Boss again!

The World Boss drops various loot, including Legendary items, Ancestral items (in Torment III+), and unique items. Each World Boss also drops unique Mount Armor and cosmetics, so you'll need to farm all three to collect them all. Here are the unique World Boss cosmetics in Diablo 4:

• Ashava: Ashava Barding Mount Armor & Ashava's Bone Fragment Mount Trophy
• Avarice: Treasure Beast Barding Mount Armor & Avarice's Gilded Horn Mount Trophy
• Wandering Death: Bone-Caged Barding Mount Armor & Bone-Caged Heart Mount Trophy

The World Boss spawns every three and a half hours in one of five zones (Fractured Peaks, Scosglen, Dry Steppes, Kehjistan, or Hawezar). Every fourth World Boss will also spawn in Nehantu.

There are three different World Bosses:

• Ashava, the Pestilent
• Avarice, the Gold Cursed
• Wandering Death
