Clan Quest Mod is an add-on for Vampire the Masquerade: Bloodlines that not only adds many new quests along with a myriad of other new features, but also integrates several other mods for the game, including the Arsenal Mod, the Camarilla Edition Mod, Companion Mod, and more!
Played through the game with this mod on. Aside from the Arsenal mod's effects and of course the annoying blood loss and feeding not healing you effects, didn't encounter many differences.
Malkavians are comparatively overpowered, by the way, given that in the Camerilla version or whatever it is makes the change they have 2 zero blood cost abilities.
