Strengths: Supernatural awareness/sight (Knows much more about the supernatural compared to others. Also can see more then normal humans should be able too.)
Tainted Blood: After his suicide attempt he spent 2 months in the underworld (Despite only being dead for 2-minutes in the mortal realm.), and later by sex with a succubus. Constantine blood has become tainted by demon-blood.
Positive Effects: Constantine's blood has shown to be absolutely distasteful to vampires. Tainted-blood has shown to have a minor healing property when consumed. (Only for non-fatal injuries, also Constantine does not get this healing effect, when he consumes his own blood.) Due to Tainted-Blood Constantine ages slower and has a higher immunity to disease. (Which explains why he has survived Lung-Cancer as long as he has.) Also despite never working out a day in his life, his physical body remains tone or fit.
Negative Effects: Because of this Tainted blood, it is excruciatingly easy for demons to track him. This causes demons to attack/pursue him constantly, not allowing him to settle down and have a normal life........ (It also proves easier for Demons to possess or manipulate/persuade him)
Divination: Using a pendulum and map, he can find locations of Supernatural/Magical occurrences/individuals
Exorcism Spells: Constantine can perform two types of exorcisms. First one is to banish/remove a demon from a mortal body. Second he can preform an exorcism that renders a demon physical, thus able to be hurt by something like a shotgun or a punch to the mouth. (Also if the demon is rendered 'physical' they are able to be seen by mortals.)
Spirit Ward Creation: Using a Sigil Constantine is able to make himself untraceable by demons/angels, despite possessing tainted blood. Basically all Sigils do is hide the bearer/wearer from Demonic or Holy entities causing them to be more difficult to find. (Constantine possesses several tattoos of Sigils, so Demonic and Angelic entities cannot sense his Tainted Blood, rather they sense emptiness.......(Vampires can still sense this blood, the scent of Constantine blood is utterly foul and dark to all vampires.)
Well-Known: Has a long list of important contacts. One being a unique items dealer, who gives him several items he uses for fighting supernatural entities.
