Blood Dance in the Dust Bowl
Here is a compilation of other minor house rules.
According to the book, Dominate will not work on a vampire that is of lower generation than the user.
The modification to that is as follows: Each dot of Dominate after the first allows the user to affect vampires of that many generations lower than themselves.
Example A 12th generation vampire with 3 dots could role to affect a 10th generation vampire, but not a 9th. Alternately, an 8th generation vampire with 5 dots could theoretically get a roll to affect a 4th generation vampire, but such a being would most certainly have enough dice and stats to shrug off such an attack.
