Create a new rule called *Items* with the following text.

This rule shall contain any items that an adventurer may hold. Items that an adventurer holds shall be listed in eir section of the Character Sheet document in a subsection named Items. An item that has already been created may be awarded to an adventurer by the DM for actions taken during an adventure. Only the adventurer holding the item can cause any changes to the gamestate that the item may allow. Some items have a number of uses called charges, to be set during the items creation. When a charged item runs out of charges it can no longer be used.

This is my take on items. Hope it works for you guys.
