Backpack
Items in your backpack can be used instead of skills for checks. They start with a die rating (d6, d8, d10, or d12) and degrade with use, just like skills.
When an item is reduced to d4, it either breaks, gets lost, or becomes irrelevant to the fiction. You can carry 3 items and 1 med kit at a time.
Med kits are special items that clear 2 stress when used. They don't degrade—they're consumed entirely.
