http://bloodborne.wiki.fextralife.com/Bell+Holder Wields the bell axe, and links me to this page. Still don't see why there should be one specific to their weapon though, it's unobtainable so I don't know how the stats will be posted or anything!
Never seen this item anywhere BTW, apparently nothing to see here guys, let's move along...
As far as I can forsee anyhow. I just got the achievement for all weapons from the dlc and saw hide nor hare of this. It's not an item unfortunately.
It's obviously not in the DLC and I don't see the point of keeping this page up.
