In battle, if you kill a foe, your enemy is down a man. If you wound or disable a foe, your enemy is down 1-3 men, depending on how they care for their fallen.
Using your assassin example, imagine he is near a door guarded by 2 watchmen. From concealment, he induces hyperthermia- a.k.a. heat stroke- in one guard. Tht guard collapses, definitely disoriented, possibly unconscious. The other must get him to help...leaving the door unguarded for precious minutes.
As for this:
I got what youre saying, but it still must perforce be more rapid than natural processes in some way. Your magic system still violates the RW laws of thermodynamics, but it is merely being redefined in such a way that the caster is manipulating reality with a profound understanding of the fictional world's physics.
In your example, you're substituting arcane energy for natural fuel, which is faster than getting actual fuel to the location you want the fire to erupt.
So, in the example of a Hyperthermia or Hypothermia spell, you're making the body react to temperatures not generally experienced at that time & place, manipulating body temperature with arcane energy in much the same way- albeit with infinitely more subtlety- as was done with the arcane energy fueled fireball.

Erm... not quite. As I explained in my first post, magic in my system's setting is not an exception to physical law, but a part of it. For example (and I'm not sure why I didn't include this example in the first place), if you want to throw a fireball at your enemies, you've got to first learn how fires burn, then you have to learn how to convert arcane energy into thermal energy, and, optionally, you have to learn how to set aside more arcane energy as fuel for the fire you'll be making, in case you don't already have something to act as fuel. If you want to make a bigger fireball, you have to learn more effective formulae and techniques for converting arcane energy into thermal energy.
