At the Storyteller's discretion, vitae from other clans may cause similar effects. The clans for which this rule most commonly applies are: Brujah (a ghoul 'pumped' on Brujah blood frenzies at difficulties equal to those of a non-Brujah vampire) Malkavaian (ghoul gains a mild Derangement) Nosferatu (Appearance drops by one or two points, but no lower than 1) Ventrue (ghouls gains a marked preference for Ventrue blood, possibly endangering the domitor) Setite (ghoul develops painful rashes when in direct sunlight furthermore, many Setites have the Addictive Blood Merit) and any Sabbat (no mandatory effect, but remember the possibility of contracting disease via Vaulderie). Note that it also tells that only some clans' vitae is contagious. I think this contradicts a little other books where ghouls inherited weaknesses last more than that overdose. Ghouls imbibing/injecting five or more Blood Points from certain clans must make a Stamina roll (difficulty 5) or 'inherit' a lesser form of the domitor's weakness this last until the vita has been purged (i.e., the ghoul holds fewer than five Blood Points from one clan).

Here comes what Ghouls: Fatal Addiction tells:Ī few clans' vitae possesses contagious properties. Ghouls that are fed for a long time, as well as those that are frequently overdosed suffer a lesser version of the clan weakness.
