Reduce Person and Confined Spaces

[PrimalWarrior]

Here is the scenario:

You cast reduce person on a captive enemy and then put them in a steel strong box that just barely fits their new size. Then you wait and let the spell wear off. What happens?

My theory:
Since Reduce Person is the opposite of Enlarge Person you might think "OK so like enlarge person the magic doesn't allow the person to be damaged by increasing in size within a confined space"

However, unlike Enlarge Person which uses the magic to enlarge the person to fill up the space, it is the wearing off of the magic that increases the size with reduce person, thus no magic is involved and there are no constraints against being crushed by the box, there would be no magic to keep the captive enemy from returning to it's original size.

An effective interrogation threat?

As far as how effective an interrogation technique it would be, it would be the same as any other sort of torture I would think. That is, it won't actually work unless it is Hollywood.

Or he will tell anything (not only the truth) to get out.

What it sure is that your alignment will move toward Evil.

This is a good question, and I am interested to see it addressed by the developers.

On a related note, one similar use that does not need any clarification is: Create a jail cell with a tiny-sized door, then cast reduce person on a medium prisoner, and force him to squeeze into the cell. Once he is inside, dismiss the spell. Viola, escape proof cell, at least against non-casters.
