Firstly, I do not remember a power called "Blood Heal" belonging to any clans, and, secondly, if you look into the matter, the dialog he includes was never meant to be included in the final release. The staff of writers was changed half-way through the production, as Troika was not happy with the original work, and the entire game was re-written from the tutorial onwards. Wesp also has broken cannon in several major places, something I can address further in the old Vampire topic if you wish to continue discussing the matter, and has refused to release a patch that does not contain his modifications -the "basic version still has many of the mods, they are just harder to notice-.
