this power surprisingly a light side power, but could in the wrong hands be a sith power, for it can make objects explode due to the force. the size of the object usually depended on how easy it was to destroy the object or make it explode. in general terms depending on the size, density and vulnerability of the object in question, combustion would become harder or easier to use successfully. it is also possible for another force user to counter it with the same power to stop it, but it hasnt been tested. the affect on inanimate objects and persons was devastating, so it was not wise to use it for harming a person.
