In Mistfall Hunter, the Watchtower Chest requires a Watchtower Chest Key, which has no fixed spawn point and must be found as loot at major points of interest. The chest is valuable because it can contain several unidentified items, potentially including high-rarity equipment, but reaching it is risky due to frequent player activity nearby.

The key has reportedly been found at the Supreme Hall, including near crucified effigies by the Great Berserker, while the Einherjar Ship Gray may also be a useful place to search. Players can improve their chances by defeating Elite enemies, opening Guarded Loot and playing in Trios; the Watchtower itself lies between Gravekeeper’s Hut and the Einherjar Ship Grave, and its chest yields three to five items ranging from Uncommon to Legendary.
