High Speed (QOS)

Dues Celeritas (神速, Kamisoku), most predominantly known as High Speed (高速, Kōsoku), is a spell of Enchantment upon the user's own body that is often categorized as it's own Caster Magic due to its ease and simplicity, allowing the user to increase their own rate of travel- speed, agility and reflexes exponentially for a variety of supplementary purposes ranging from high-speed travel to assisting their combat abilities.

Overview
High Speed is a spell of Enchantment that has in a sense become it's own form of magic, despite its roots. It enables its users to enchant their body itself, increasing their speed, agility, and reflexes in numerical rates known as Gears (歯車, Haguruma). Each Gear increases the user's rate of travel by means of a formula. Gear One (歯車一, Hagurumaichi) is a base speed of 50mph, though by using a term known as Gear Change (歯車変更, Haguruma Henkō), the user is capable of 'changing gears' to increase or decrease their speed by the formula: 77.5mph • x mph, filling in x with the 'gear' they wish to change to, numbered zero through ten, zero as their regular speed and ten as the max speed achieved through this spell, at 775 miles per hour, breaking the sound barrier. This allows the user complete adjustability over their top speed by range of their gear, as they are able to move at speeds lower than the gear they are operating on but not higher. To enact this effect, the user expends some of their magic power to change gears, however, once they have changed gears they expend no magic power until they change it again, which is required at least once for when they return to zero. High Speed allows it's users to move on higher gears at such a rate that they seem to leave afterimages behind as they move, disappearing and reappearing in a flash of their magic energy much like teleportation. Overall, this magic is incredibly useful and fairly simple to learn, once one has the concept down, making it one of the most commonly used magic across Ishgar.
