Charging Boots of the Light Thief

The wearer of these boots can charge through obstacles by transforming into an image of light vaguely similar to themselves as they charge forth. The speed of the charge is blurred do the speed with which the movement takes place.
The wearer dematerializes at the beginning of the charge and materializes in the square they will end the charge. The ending square must not be occupied. A direct line of sight must be present and as long as it is, it doesn't matter what lies between point A and B. This spell, due to its nature of turning the wearer into light, bypasses all transparent obstacles like glass or walls of force.
With very few exceptions, attacks of opportunity are not allowed as the wearer moves through areas of threat. However, leaving the starting location of the charge can incur an attack of opportunity as normal.
