This Challenge is part of the Fortnite Winterfest missions. It will ask you to open a frozen loot. Don't confuse it with ice reserves, which are the sort of large iceboxes. Frozen Loots are those huge cubes of compact ice found in various places on the map.
The Map
The landmark of Shiver Inn, southeast of Lazy Lake, contains a very large amount of frozen loots. The problem is that in the week following the release of this challenge, it is likely to become a more crowded spawn than usual!
Frozen Loot is difficult to obtain in the sense that the block of ice has 3500 life points. That's just huge and you'll need a total of 35 picks in the weak points of the material to discover the reward and validate the challenge. Digging through the ice will take you a while, so make sure you've checked beforehand that there are no enemies lurking around, and equip yourself with a minimum of equipment before you start destroying the ice block.
We recommend that you use the Team Rumble mode to complete this challenge, especially during the week following its release. It will reduce the chance of running into warring enemies as soon as you land.
