Mage/Adept/Sniper/The Professional Options

[yoippari]

I want to build a character that is similar to Leon "The Professional" in the gun skills but prefers being sneaky with a knife but as an adept/mage (which ever works better) with abilities similar to Karl (whose skills are => Leon's) in Ted Dekker's "Saint".

Karl can focus and alter his body tempurature, but he can, with effort, alter the tempurature around him. With finding out he can do that he tries to apply what hes doing while meditating (the tempurature thing) to his sniping. He is able to control the bullet in flight out to 1200 yards (the length of his target range). He even alters his bullets path to enter at an angle where no real damage is done (muscles are torn, but no bones or organs are hit). He also goes into a deep meditation where he is pretty much useless for anything but this focus and manages to survive an electric chair.

Some of this sounds like adept stuff, but stuff like altering a bullets path seems more like a manipulation spell. So is this just specific instances to use abstract stats like a really high longarms skill? or is it entering the house-ruled power/spell area?
