+When the fiction allows it, you can make a loot check to scavenge for tools, weapons, med kits, etc. You start with a d12 loot die, which steps down after each usage. When you loot, roll your current loot die and interpret the result. You may continue to use the loot die when it is a d4, at your own risk. To reset your loot die to its initial rating, you need to catch your breath.
