Leaping back away from the terrible beast's initial charge, Sorin repelled what lightning he could with his blade, but a few struck him glancing blows. His armor took most of the damage, but he could still feel a few minor electrical burns. He ignored the pain; a few wounds were nothing to him.

A few others that Sorin did not have time to pay attention to made the scene, continuing to harass the monster. This enraged it, giving Sorin exactly the opening he needed. He unleashed the building mana he was accumulating on the creature, forming the spell with an incantation. With a few words of black speech, a curse in an ancient Vampiric tongue, the monster's fate was sealed.

This power was the reason the vampires of Zendikar knew Sorin as the "Mortifier." As the spell connected, it would corrupt and decay the beast where it stood. Its flesh would slough away and spoil as though suffering from years of rot. Its blood would dry up in its veins and its brain would ferment in its skull. However, above all else, its corpse would serve Sorin in death, his mind taking mastery over its deceased one.
