Lily took several steps back from the point of danger where the warning had emerged. She contemplated the hulking figure in the distance. She would need to somehow close the distance, destroy a part of its armor, then get close to the damaged spot without dying. Judging from the multitude of skeletons that littered the landscape around the thing, its killing power was immense.
To achieve her objective, she would have to rely on the advantages granted to her alone - she would have to rely on her metallic legs.
Her prosthetics were initially intended to make up for her handicap, but as she was carried by them on her way to this point, she had come to view them as powerful tools. They required no energy and never tired. By increasing the amount of mana granted to her legs, she could dramatically increase the output of force and kinetic energy. They could move and change directions faster than any organic limb, and with no bones to crack and fully round joints, they enjoyed a free range of motion which allowed them to be manipulated in impossible ways. It was possible, for instance, for her to rotate her calf a full circle around the knee joint without issue and at high speeds. Made of metal, reinforced by mana permeating them, they were far more durable than any organic tissue.
If she was to accomplish her goal, she would need to learn how to best utilise these properties to her advantage. That required training, and experimentation.
Back in Azoria, there had never been much opportunity for learning how to fight. It was the famed Academy City, after all. It was the home of researchers, of teachers, of academics; not of warriors or mercenaries. Most of the adventurers who ventured into its Labyrinth were simply passing through, or otherwise warriors attracted by the high volume of lucrative Escort quests frequently issued through the Guild. With the exception of a few family-run dojos and schools, there were few places to learn martial arts within Azoria, and minimal interest amongst the populace in putting in the time to practice it.
That said, Lily had, at one point, read up on various forms of Martial Arts when she was undergoing a self-conscious phase and obssessed over keeping her body in shape. While she had eventually settled on running as her main form of exercise, she had read books on the theory and basics of martial arts.
Having created significant distance from the point of the warning, she bounced on her heels and experimentally, clumsily, attempted to throw a kick in midair. The power of a kick was, she knew, derived from the amount of force applied, as well as the angular velocity of the limb. Therefore, she attempted to bring her artificial leg as high as possible. With the upper section of her thigh still being organic, the angle she could attain was limited, but she brought it to the maximum permissible. Naturally, this movement caused her weight to be unevenly distributed, and as she was winding up, she lost balance and fell to her side, landing hard on the ground.
She grumbled as she got up, then re-attempted the kick. This time, she made conscious use of her other leg as a counterweight, going through the motion slowly as she slowly adjusted her weight, keeping her centre of gravity level. As she completed the motion without issue, she reset her position and did it again. And again. Numerous times she performed the slow-motion kick, carefully memorising and habitualising the numerous minute shifts in weight. When she was satisfied with her form, she did it faster, but with minimal force. And again, faster. And again, faster.
When thirsty, she drank. When tired, she slept. Throughout it all, she continued to practice the kick, going faster each time. By controlling the form of her magic, she could use her magic's manipulative property to artificially increase the speed of the leg while only minimally increasing the kicking force, by simply visualising the faster movement of the limb through space, changing the magic's <
