Vampire Disciplines House Rules

I've been looking up house rules in the source books and websites and have come up with a few house rules.

1) All vampires and dhampirs may take Potence, Celerity, and Fortitude without having to consume the blood of a vampire that has these disciplines as in-clan. The cost remains the same.

2) For someone to learn an out of clan discipline, besides the three physicals, the student must consume at least 1 blood point of the teacher. The teacher must also possess at least 1 dot more than the level the student is trying to learn. (E.g. If Stu the Nosferatu wants to learn Protean 1, his teacher must have at least Protean 2). After consuming the first point of blood, the vampire does not need to consume any more to learn the first 5 levels of the discipline. After the fifth dot the vampire must consume the blood of the teacher each time they wish to learn a new level. After learning the second dot from the teacher, the student does not need the assistance of the teacher until they wish to learn the sixth dot and above.

3) Celerity activates the same round as the blood expenditure to activate it. We are using the Masquerade Celerity cost of 1 bp no matter the level.

4) The time it takes for a kindred to learn discipline dots 6 and above, the kindred must spend a number of years to research it equal to their Willpower minus the dots of the discipline trying to be learned.
