Physically, Harry Dresden's height and appearance can work against him, lending him a look that is at best unpleasant and at worst outright frightening. The sorts of threats he typically faces rarely are intimidated by this appearance, but those he might otherwise consider allies are frequently put off by it, rendering this far more of a drawback than an asset. Additionally, he is just a normal wizard, and one with little physical training outside of regular running and a few hours a week with Murphy at the gym- when he remembers and isn't too busy. He is, therefore, a pretty squishy guy, and if you take away his magic there isn't a whole lot left. Just a tall, smartish guy who runs a lot and fights dirty. Mentally, Harry lacks any sort of special education, and can frequently lack in knowledge of the modern world. He is not a genius-level intellect, nor is he an expert in any particular field- even his magical theory, outside of practical knowledge, is far outstripped by that of other wizards. Additionally, his judgement can become heavily impaired by his emotions. Emotionally, as mentioned, Harry is very temperamental. He's capable of anything from blind, wrath-of-god rage to blind self-sacrificial chivalry to blind self-deprecating misery, with few pit-stops inbetween. Note the use of the word blind in all three cases- his incredible perception is one of his most valuable assets, and it is frequently the first victim of his emotional nature. He can also be quite socially inept, unable to deal with people on any sort of subtle or intuitive level. Magically, Harry's power essentially makes him little more than a thug. As mentioned before, anything requiring extreme power is right up his alley- and anything else is right out. Precision, flexibility, control, sensitivity, these words want nothing to do with Harry's magic in any way. His time working with his apprentice, Molly Carpenter, has helped him to work on some of his more subtle Illusion magic- and only now, after years of training with her, has he even managed what for other practitioners would be a rudimentary veil. His use of magic is powerful and flashy, but it is also inefficient, as much energy going into the bright light and the big noise as actually into the magical effect he's trying to achieve. This also extends to his entropy field. All wizards have an entropy field that they emit which renders electronics and other advanced technology in the area prone to instability and malfunction, but Harry's is commonly cited as among the most severe. It affects a larger area, it has a more consistent- and more powerfully detrimental- negative effect on technology, and the breadth of technology vulnerable to it is far wider than that of many other wizards. While this occasionally serves as an asset, as it allows him to more easily disable said technology deliberately, even that is unreliable- hexing a video camera is as likely to cause every device on the same electrical circuit to short out and even combust as it is to simply disable that one device. Note: Harry's entropy field, like his power, will be severely curtailed by the power regulators in Luceti, to the point where he's unlikely to be a danger to technology- or to technologically-inclined residents. It will still interfere with his own attempts to utilize said technology, however.
