[@Cruallassar] I have to interject on that last part. Magic is not a separate entity from physics, but simply another side to it. Science and magic are more closely related than you may think. Magic, on most occasions simply manipulates physics and interactions between objects that give the appearance of outright defying them, but most of the time does not actually break physical laws.

To increase the 'energy' of a sword strike, you'd need some form of increase in speed or mass, because an objects energy is determined by those two factors. There are many ways to increase an objects damage potential with magic without just saying 'cuz magic', because while it might be magic, every action in RP still needs to be at least somewhat logical.

just thought I'd give my two cent.
