Rotting. As a member of Morte D'Amour's he could make his body rot into a decaying corpse or even fall apart without suffering damage. This made him extremly hard to kill.
Corruption. A very rare ability even in Morte D'Amour's bloodline who is the only other vampire known to posses it. His bite nearly killed Nathaniel, but Asher and Damian were able to save his life with Anita's help of her necromancer powers.
