The reinforcement path of the Devil Hunter series had appeared in Infinite Dawn, though it only provided the name of the primary attribute, Vampire Hunter, and the power description of the intermediate attribute, Devil Hunter.
Because the character who used this attribute-based reinforcement, Xiao Niaoren, used a whip—the Vampire Killer? Possessing a technique that set the whip ablaze—Fire Whip? Using a red heart for the unlimited use of holy artifacts—Item Crash?
Furthermore, there was a skill called Dracula's Gift, which, if used three times, would result in the user being dragged by Dracula into Castlevania.
