If your farming the key chests, if you still have the buff once you have found the chest, you can leave the area and come back and pick up the chest again. Best place to spam the chest is the skywatch. You can loot the chest roughly 3 times before the buff goes away. Though you guys should know :) Edit: chest locations Chest 1 - by entrance of loner complex Chest 2 - outside the centre building with the blue Russian sign Chest 3 - by the rusted trucks near the centre building Chest 4 - Top of the building you exit as you come from the terrestrial compound Wolf pack spawn points As you look at the building with the giant green anchor....thingi, the spawn either on the left or right side of the building. They also spawn by the helicopters Fastest way to leave the area is to go to the liner complex as its only a short trip down the long corridor to the entrance of the next room. Just pop the nose of your sparrow in and it'll change Hope this helps :)
