His defensive position made it easier to react to the coming onslaught of the undead. He knew not yet the fighting style of the this one, but he had fought numerous of its kind before. Vampires, usually, fought by simply overwhelming their opponents with their superior physical capabilities. Vampire mages were even stronger - for they had both physical capability as well as arcane. He was not exactly sure how old this one was - its age made a big difference, for nearly all older vampires learned the arcane arts. Younger vampires also had considerably less combat skill. Considering his own physical disadvantage, he decided that playing defensively while gauging his opponent's skill was the best bet.
His incredible mind had already begun mapping out his enemy's moves. He observed the way the undead made its movements, as well as the look it kept upon its face and within its eyes. At first, the vampire ran directly at him, but Alistair knew that his opponent would likely attempt to switch its direction of attack. Attacking head on would be foolish of the creature, for it knew the divine energy that Alistair could summon. Still, he hoped the creature would have been foolish enough to strike him head on, so that he could impale it with his Shining Blade Mantra. Had the attack gone as planned - and it most likely would have - the vampire would have been instantly slain.
But like most things in life, it would not be that simple.
Out of the hundreds of possibilities that Alistair had come up with in that short time frame between Elliot's jump to action and his stop six feet in front of him - just out of reach of a decent swing that would not leave him too open - the action that Elliot chose was, of course, one of them. His own eyes watched, observed, memorized the movement patterns of the creature up until he saw its right foot move as if to kick something. Expecting dirt to fly towards his face, he immediately shielded his eyes with his left arm. At this very same moment, his eyes and sword took on a sudden strong golden glow. Just like the glowing orb in his hand before, Elliot would surely be able to tell that touching it would be a very bad thing.
His arm had blocked the dirt, but the vampire had already made its next move. Its physical speed was probably about as fast as his own mental speed, but if his body could not keep up then it was irrelevant how fast he processed information. He expected an assault to come immediately after the attempted blinding, and surely enough it would come just as his blade lit up with Divine energy. It was difficult for him to see, but his peripheral vision allowed him to make out an incoming attack to his right. Despite having difficulty seeing it, the information he gathered was enough to discern the exact target of his attack. Recalling information he gathered from earlier, he knew the exact height of his opponent including but not limited to the length of his legs. Immediately he spun his body towards the direction of his enemy while simultaneously bending his upper body backwards, causing the kick to glide right over him harmlessly, barely missing its mark. At the very same time he spun to his right to face his opponent, he swung with his glowing longsword using only his right hand. Assuming Elliot did not alter or pull back his kick, his leg would collide with the blade instead of Alistair's body.
Such a situation would not fare well for the vampire. Despite it being made of mundane steel, the blade had been enchanted with Divine energy just prior before it would connect with Elliot's leg. Not only would Elliot's leg be cut clean off at the point of impact - not doing so much as even budging the sword, despite Elliot's far superior strength - but the Divine nature of the blade would burn Elliot's flesh as the Divinity began to devour his undead flesh. Even though vampires typically did not feel pain, Elliot would feel a very painful burning sensation from this attack. The glowing coming from his eyes and sword would vanish immediately upon the swinging of his sword, whether the attack hit or not.
Regardless of whether or not his counter-attack connected, Alistair would attempt to gain some distance from his enemy. Preferably through following up his bent-backwards shape with an immediate backflip, landing on his feet facing his opponent but several feet away from him. He would take a defensive position once more, again irrelevant to the outcome of his attack.
