Can a 20-ft. cube can be disassembled (if shapeable) into 8 10-ft. cubes?SRD said:(S) Shapeable
If an Area or Effect entry ends with "(S)," you can shape the spell. A shaped effect or area can have no dimension smaller than 10 feet. Many effects or areas are given as cubes to make it easy to model irregular shapes. Three-dimensional volumes are most often needed to define aerial or underwater effects and areas.
How does shapeable work with something like Control Water? I've been interpreting it as saying that you could affect a smaller area than desired; a 100 x 200 x 40 foot area instead of the 200 x 200 x 40; that would still be "squarish." But you couldn't make a series of troughs in the area, or selectively lower areas to produce a lot of little 10-ft. square "pillars" or whatever. Now I'm not so sure.
Earthquake is also shapeable, and it is even less clear how that would work. Again I'd suppose that you could affect a smaller area than desired, but you only have one "dial" to control; the radius of the spread. Can you be more selective than that? Can you spare particular squares of ground?
How would you interpret these spells?
