I'm curious about how to define the characteristic of the elements
being borrowed from one element to be placed in the other.

My example is a locked door and a glass of water. I want to take the
fluid motion of the water and apply it to the door, so the door will
just collapse and I can walk through.

If area is a concern, I would only go after the door knob to assume
that I could push open the door since the looking mechanism fell apart.


Do I have to be able to touch both elements in order for Khemia to
work? The examples with fire seem to imply that I only need to be
'close' to make this work properly. (the power gamer in me sees using
this serenade to make the squishyness of a marshmallow be applied to
the sword attacking me - or the low melting point of water to be
applied to a metal gun firing at me).

(since ODP is on this forum) How close of a definition of the
characteristic do I need to make?

And finally, assuming that I can get a semi-permanent effect. Can I
use the same target item for multiple effects? I want the flexability
of a shadow for my shirt, but I also want to apply the 'anti-ripping'
nature of kevlar to make a lightweigth bullet proof shirt that's stylish.
