Athinar's grin widened even more, as he missed. The Vampyr was above this body's ability level. Magnificent. Pupils dilating, and nostrils flaring, the Void Lord turned flesh saw the magical bolt approach him. It didn't seem to be damaging, but rather, a spell that would mildly inconvenience him. Still, probably better to not let it hit him. 

Arcane energy surging up from deep within, Athinar spoke an ancient Word, and saw the green bolt slow down, as his perception of time caught up with his physical capabilities. The air around him smelled like ozone, after a lightning bolt, and there was a brief flash of light in a nimbus around him, (not blinding,) before the spell took affect. He was now, effectively, superhuman.

Sidestepping the spell, and allowing it to splash into the wall at the far end of the corridor, Athinar, rather than grab the sword, or dispel the Blade of the Void, which was still hanging in the air, ducked down, under the assumed angle of attack, and, lifting up, aimed a haymaker at the Vampire's chin. It wouldn't do much damage, but hopefully, it would surprise him, and cause him to get stunned.
