Game specific information
Found in the Infinite Corridor exclusively in Trevor Mode (thus it can only be used by Trevor Belmont). The Holy Whip is the only weapon in that gameplay mode that can kill Blood Skeletons (acting as a counterpart to the Purify spell from Hector's quest).
In Portrait of Ruin, the Undead Killer is nearly on par with the Vampire Killer in terms of strength and holy power. The Undead Killer's greatest asset is that it can permanently kill Red Skeletons and Red Axe Armors. It can be acquired by completing "S Rank Hunter" quest.
The Undead Killer's Critical Art in Castlevania: Portrait of Ruin is very similar to the Vampire Killer in that the damage dealt is doubled and adds the Fire attribute. This makes the Undead Killer effective against highly resistant enemies, such as a Final Guard.
Strangely, if one is using this whip on Vincent when he has been afflicted with vampirism, it will cure him of the aliment, just as if Sanctuary had been cast. Why it would be able to do so is unknown, as its power lies in destroying what would otherwise be impossible to kill.
