Imagine, if you will, that the usual confluence of improbable occurrences supplies you not only with a Philosopher’s Stone, but also its instruction manual. Not being an idiot, you read the latter before doing anything major with the former. You discover the following:
The unit you have is stuck in “Do-Gooder Mode” and can only be used for unselfish acts. To get it out of DGM you’d need to head on over to the fantasy universe it came from, but to open a trans-dimensional portal you’ll also need the product key. Hacking the Stone is not a option. Try to use it for evil once and it’ll lock up for one hour; a second time and it’ll lock up for one month; a third time and it’ll destroy itself, but not only after killing you in the most painful way imaginable.
At its current settings, the Stone can only be used for three purposes: transmutation, teleportation, and cloaking. Specifically, you can transmute any inorganic matter into another form, so long as the target form is (a) a pure chemical element, or (b) one of the following compounds: water, light sweet crude, or pencillin. Again, it’s not a matter of mastering the stone, it’s that damn missing product key. Stupid MagicSoft.
You cannot create new matter; the mass of the original substance and the new one will always be the same. You cannot create machines, just raw substances. You can teleport yourself, the stone, and any matter you have used the Stone on to any location within the dominant gravitional influence of the Earth, so long as you know the exact latitude and longitude down to fractions of a second, and so long as no other matter is in the spot you want; you cannot teleport organisms other than yourself. You can use the cloaking function to mask the stone, yourself, and your clothing to any surveillance, but nothing else.
Make the world better.
