Can a vampire purchase multiple powers at the same level of a discipline?

Question

One of my player is interested in two powers that are on the same level of a discipline, and I couldn't tell him if he can take both one way or another. So here is my question: Can a vampire purchase multiple powers that are on the same level of a discipline?

My guess is "Yes, but you have to get another point in this discipline to get it", but I also see a house rule that says:

LEARNING DISCIPLINES Vampires can learn multiple powers from the same discipline by purchasing its dot level a 2nd time as an in clan discipline.

So after I've seen that house rule I started thinking that RAW you can't purchase same level powers.

Answer 1

Your guess is correct: Yes, one can.

If you get a second dot in the discipline, you can learn either a second-level power, or you can learn a second first-level power. That does mean that you're not learning that second-level power. If you want to learn that one, you'd need a third dot in the discipline, and you wouldn't be learning the third-level power if you choose to learn the second-level power.

That house rule seems to be there to allow you to eventually learn all powers if you sink enough experience into the discipline, while the original rules would only allow you to learn 5 powers total. (5 dots in the discipline.)
