Item Visualization Spec Oracle
The Item Visualization Spec Oracle is a Spec Oracle, or set of definitions, in Hero's Journey. It is included as an example in this wiki, on pages such as the Inventory Tutorial, but it is not a part of Clean Engine. Since inventory is so entwined with a particular game system, licensees make their own inventory and item visualization systems (or spec oracles) as needed.
