Is there any limitation on how many dots can be purchased at a time? e.g. one attribute dot per advancement, perhaps? I saw this somewhere on the inter-webs, but cannot find the post again, so I don't know if that was a house-rule or a reference to the standard rules.
I request that answers reference page numbers or other sources if at all possible. I have access to both the GMC rules update document and the V:tR 2nd Edition core rules, both of which are fairly sparse in their advice on experience and advancement.
