==== House Rules/Interpretations ====
  * In general, anything costing up to 15,000 gold is fairly readily available. Anything costing more is not usually for sale for money.  
    * Cauldron is small. Anything less than 5000 gold can be found just by walking in to a store. Up to 15,000 might be on the shelf, but can definitely be special-ordered.     
  * //Wish// does not screw you over for using it for any of the listed purposes. If you use it off-label, it is capricious.
    * //Wish// adds the 3.0 limitation that it will only safely create you an item worth up to 15,000 gold.
  * 40 feet of solid material blocks (nearly) all spells. 40 feet underground, you can't scry on the surface or teleport there, and vice versa.
    * Permanent effects that take time to set up (e.g. portals) are often exceptions.
  * //Polymorph// uses the latest errata. 
  * The swift-action changes replace all the weird casting times (like for //feather fall// and quickened spells)
  * The Rules compendium is a summary, not a primary source.
  * Divination only works reliably if I have enough forewarning to come up with a response easily.
  * Mindless undead: 
    * Controlled mindless undead are mostly automatons. They're evil because they are powered by evil batteries. 
    * Uncontrolled mindless undead either do what they were told last, or search for life to destroy.
    * Mindless undead usually do not interact with illusions, and usually automatically treat them as real.
