Additional Headhunt Mechanics
Exposed Roots and Uprooted Cocoons:

As you complete Whispers, you'll find Exposed Roots. Interacting with these gives a chance for Diablo 4 Itemsto  spawn rare variants of Headrotten, which drop valuable rewards and seasonal currency.
Uprooted Cocoons are special interactives that can spawn Headless Husks and Fugitive Heads when triggered. These are the only sources for obtaining Fugitive Heads, so it's crucial to hunt them down whenever they spawn.
Uprooted Cocoons can be triggered by you or other players in the zone. These will appear on your map, so take advantage of cooperative play to maximize the chances of spawning these valuable resources.

Fugitive Heads:

Fugitive Heads are rare drops from Headless Husks and Uprooted Cocoons. These heads are required to obtain Occultist Gems from Gelena, located near the Tree of Whispers.
Fugitive Head spawn chances increase with Torment levels, and you can further increase your chances by using a Draught of Whispers, which doubles your chances of finding a Forgotten Altar or Lost Altar, as well as increases the likelihood of encountering Fugitive Heads by 50%.
Killing Fugitive Heads yields a Fugitive Head item, which is turned in to Gelena for Occult GGemskey component for progressing in the event.

Silent Chests:

Within Headhunt zones, you will also come across Silent Chests. These chests are static and have pre-determined locations, unlike random loot chests.
Silent Chests can contain important rewards, including the Whispering Wood Sigil, which is required to gain access to Roothold's special endgame mechanic akin to Nightmare Dungeons.
To open a Silent Chest, you must purchase a Whispering Key from the Purveyor of Diablo 4 Items for sale Curiosities, located in most towns. These keys are essential for accessing the rewards inside Silent Chests.
