Scrael's body was already nearing its limits due to almost all of her mana surging through it wildly, empowering it and forcing her to move at speeds faster than she could handle. But it was the bare minimum necessary to scratch the Stone Demon, so Scrael couldn't stop or change methods. Not that she had any other way of attacking that would actually damage the demon.
Her body was burning with aching pain due to the pressure put on it by her magic. But there was one exception.
Her prosthetic leg.
The leg was slightly lacking in finesse and delicacy but could handle magic and mana just fine. And since she couldn't feel anything in it, she wouldn't be burdened with pain or cramps if she overloaded it with mana. Although she didn't have a way to replace it if it broke, it wouldn't be the first time she lost her leg, so it didn't even matter if it couldn't handle what she was going to put the prosthetic through.
With an idea, resolve, and an opponent only defending passively, Scrael started channeling all her magic into her leg.
The magic coursing through her body flowed into the leg, and Scrael started dragging up all the mana in her mana pool to further strengthen the magic inside her leg. It almost felt like she was making a breakthrough since she continuously compressed and strengthened the magic in her leg. But it was nothing more than a superficial similarity since the power inside her leg wasn't something that a breakthrough created.
The overflowing amounts of lightning mana struggled to break free from the constraints of the leg, but Scrael suppressed it and reigned it in. However, she couldn't endlessly keep strengthening the magic in her leg.
The wooden leg might be resilient and sturdy, but it had its limits. Scrael was also limited in the amount of mana and magic she could use and control at once, not to mention the amount of mana she had left in her mana pool.
Eventually, when the leg fizzled and crackled with sparks of lightning to the point where it looked like Scrael had stuffed an entire thunderstorm into her leg, she decided it was enough.
Her leg was filled with so much rampant lightning that she didn't even dare touch the ground with it since she was afraid it would disperse. And since most of her mana was concentrated on the leg, she wasn't reinforcing her body more than the bare minimum. Hopping on three legs and with no mana to strengthen her body, Scrael's speed had dropped to less than a fraction of what it was earlier.
However, the Stone Demon was still locked in a defensive position and didn't seem to be about to make a move to attack Scrael. She still kept her guard up as she approached, but she wouldn't let excessive caution prevent her from attacking the Stone Demon.
With a final burst of physical strength, Scrael shot off the ground toward the Stone Demon. She reached out with her lightning-packed prosthetic leg and directed it toward her target's chest.
The lightning began escaping her control before she even touched the demon, and electricity sparked between her wooden paw and the demon.
A sizzling hum filled the air as more and more lightning left Scrael's paw and entered the demon. The lightning continued building until the bright light obscured the sight of Scrael's paw and the Stone Demon's chest.
However, when Scrael's paw finally came in contact with the demon, all the lightning went straight into the demon, none of it escaping into the air.
The concentrated power of the lightning forced the demon to grunt in pain at first, and the demon struggled to keep its demonic energy in control and keep up its defenses.
But as time passed and the overwhelming amount of lightning flowed into its body, the Stone Demon's body started burning and twitching. Smoke poured out of its ears, and its remaining limbs twitched around like stranded fish. But no matter how much the demon struggled, the point on his chest in contact with Scrael's paw didn't budge, and neither did Scrael herself.
The electrical tension and discharge kept her suspended in midair as she continued unloading all the lightning she had built up in her leg into the demon.
Despite not having a sense of touch in her prosthetic leg, Scrael could still sense the incredible pressure she was putting her leg under. Thankfully, it seemed like the leg would hold out long enough for all the lightning she conjured to enter the demon's body.
However, it wasn't without a cost. Using so much magic strained her mind, body, and mana pool, even if she used her leg as a catalyst instead of her body. Combined with the fatigue she built when she ran so fast that the world slowed down, Scrael could feel her body turning off. Her eyes returned to normal, and her fur stopped shining. But her leg still glowed with an electric light as it continued emptying all the lightning magic into the demon.
But it was clear that the power was gradually lessening. And with the decreasing might of Scrael's attack, the effects suffered by the Stone Demon also decreased. Its insides were heavily damaged by the lightning that had surged through its body. But it could still use demonic energy to control its body in a last-ditch attempt to counterattack now that the electrical currents were no longer forcing his limbs to twitch uncontrollably.
Scrael, who didn't have much mana left and was exhausted, noticed the demon's arm heading toward her, but her eyelids were so heavy she could barely keep them up, much less move her body away from the Stone Demon and dodge its attack. But she could use the remaining dregs of power in her leg to shoot herself off of and away from the demon, which she did. Or at least she tried to.
