I got the mods from every person to drop a bloodborne mod on nexus for dark souls 3 i do not own any of these but i thought id share what i whipped up with everyone. I'm sad bloodborne never made it to pc so enjoy.
Theres purple sfx, the bloodborne menu, sounds, weapons, armors, the lamp, and some items, most of the bosses have been replaced by ds1-3 and demons souls bosses, one includes lady maria from bloodborne, a nude mod (dont worry about this its only with the masters attire) and a werewolf mod. More will come in the future when the nexus modders drop the required files.
Edit: added more bloodborne items changed a few items files around and added more enemies and weapons
Bug with dragon slayer armor can be surpassed by quitting out then reloading
