Dunno about that
I remember spending a lot more time using the vampirekillers chain form than it's much weaker leather one in the classic games, Portrait of ruin's vampirekiller isn't leather, and when Rondo ditched whip upgrades it was the chain whip that they kept not the leather one.
I'd say that in game the vampire killer is more frequently shown as a spike ball & chain whip while outside of the games (in artwork and such) it is more commonly depicted as leather, probably because a leather whip is a heck of a lot easier to draw & use.
In regards to the video
I found it's portrayal of the Belmont clan to be pretty stupid.If the Belmont clan didn't care one bit about the rest of mankinds fate then their sole motivation for fighting Dracula would be because one of their long dead relatives told them too, which on it's own is kind of a pathetic.
Vampire Killer is Always Leather...
In the Official Artwork...
yet always Chain in the Games....
Question is, when will there be anyone that Actually
knows how to use a whip in the castlevania universe
because a Leather whip is both more effective and lethal than a Chain one.
When will we ever get disarming and using the handle as a club?
