The D4Planner event timer shows how long until the world bosses, helltide events, and legion events start, and provides future times for expected events to occur. Click the button below to enable push notifications so you never miss another event!

• World bosses spawn every 3.5 hours, and players are given 15 minutes to kill them before they disappear.
• Helltides are always happening, and reset on the hour.
• Legion events occur every 25 minutes.

The map below shows world boss spawn locations as well as mystery chests (red) and seasonal living steel chests (purple), the chests that are currently active have a glowing dot above them. Active chests rotate on the hour.

Tortured Gift of Living Steel chests during the helltide event require 300 cinders to open, and you'll need these to farm mats for Uber Duriel, which is the primary method to obtain uber uniques in Diablo 4 Season 2.

Tortured Gift of Mysteries chests during the helltide event require 250 cinders to open, and are a great way to farm high value legendary items.

Once per week, per boss, you can obtain a Grand Cache that generally contains powerful legendary and possibly unique gear.
