Ok, whether or not you liked the movie... or The Novel, you cannot deny that the portrayal of the drug known as NZT-48 (or MDT-48 if you prefer) is awesome!!!
I would like to make this Drug in my upcoming Planescape game!
Now I know you can simply say, "Uh, try a potion of Fox's Cunning... duh". But that just doesn't have the same impact. I was thinking more along the lines of a bonus to all mental stats... and maybe dex as well (heightened reflexes).
Being a drug however, would come with it's drawback. It would be highly addictive and have a nasty DC to resist. Not to mention so insanely expensive, it would be VERY difficult to find/purchase.
Open to all suggestions!!!
