Add a rule called “Inventory” with this text:

Each Tesser has an Inventory, tracked in the GDNT, which is a list of words, which are Items.

If the rule “Orientation” is enacted, add a new rule called “Alchemy” with the following text:

If a Tesserer makes a Story post with the tag [Tessered X], they may in that post state that they wish to perform an Alchemy, by choosing an alchemical formula with a time value which is less than or equal to X. If the Tesserer pays the list of shards, and complete all the other requirements, and the orientation of the Tesseract is in one of the allowed values at both when the post is started, and when it ends, then that Tesserer adds an instance of that object to their inventory.

An alchemical formula consistis of 5 parts: the name of the object, a list of shards, a list of possible orientations of the Tesseract, a time value, which is a number, and possibly other requirements. They are listed in a rule called “Alchemical Formulas” which is a subtle to this one.
