Create the following rule, called “Storage Room”, with the subrules “Items” and “Inventory”:

Each Zone by default has a subrule called “X Loot Table”, where X is the name of the Zone. Loot Tables are never Zones. Each Loot Table contains a list, which defaults to empty. Each entry in a Loot Table’s list is referred to as an item and must be in the following format: “Name (percent)”, where Name is the name of an Item and percent is a number between 0 and 100, non-inclusive. The sum of all percents in a single Loot Table may never equal more than 100.

Items:
The following is a list of all Items which may appear on Loot Tables and in Inventories. Entries on this list must be in the format “Name: Effect”, where Name is a term which describes the item and Effect is what that Item can do. If there is ever an Item which is in a Loot Table or an Inventory which is not on this list, that Item is removed from wherever it appears.
Flashlight: No Effect
Toolbox: No Effect

Inventory:
Each player has a publicly tracked Inventory. An Inventory is a list which may contain a list of Items, and defaults to empty.
