Re: Harry Dresden
One thing the show never seems to really touch upon is the fact that his level of magic and technology don't really mix well. He can't go near computers or they puff smoke and die. His car (an old VW Beetle) works for him (when it isn't too beat up) because it is lower tech. Electricity doesn't work for him for very long, so heaters, AC, elevators, etc.. fail pretty regularly around him if he doesn't try hard to hold back his magic (aura?). So, he gets lots of nice cold showers since water pressure works, but not a water heater. He uses candles since light bulbs don't seem to last long.
His blasting rod is a fire focus, his staff is an air focus.. Without them he uses up a lot of energy to try and get off similar, though less controlled, effects. He can't do TK. He simulates it with air control (such as summoning his staff to him by using the wind to pick it up). His duster has been enchanted from the beginning (Storm Front) to act as a barrier providing him with rPD/PD. The charm bracelet stops kinetic energy, but not other forms like heat or cold. He can control the shape and orientation of the shield, but he can't keep it up without some effort (so it doesn't stay up if he isn't awake and choosing to power it). The rings build up kinetic energy by absorbing energy when he moves (making it take a little more effort to walk, but not noticeable).
