Crucifixes were one of a Vampire's several weaknesses and possessed two non-fatal effects to them. The very sight of a crucifix was capable of fending off a vampire and the second could cause a vampire plainful burns through contact. Even though crucifixes were ineffective to the Turok-han, they also worked on Ethros demons.
Despite the fact that the term 'crucifix' refers to a cross with the image of Jesus Christ, any plain cross of any material was was still capable of harming vampires without the original purpose as an object of worship.
Exactly how or why vampires are turned away by the cross was never explained. Conversely, many vampires considered the crucifixion to be a glorious day for their kind, and many even went on to bolster their status or power by claiming to have personally witnessed the crucifixion.
