Ability Augmentation is the ability to enhance the powers of oneself or others.
Vincent has the ability to slow down and redirect the hemoglobin in his blood to heighten specific senses. Vincent mostly does this when he is tracking. He uses this ability to see in to different light spectrums to tract people he is hunting or searching for by following day or days old foot and finger prints. On several occasions, he was seen being able to use this ability to near psychic-like levels in that it actually allows him to perceive past occurences.
Tori uses this ability to heighten all of Vincent's physical attributes so that he could help her escape a bomb.
