Yo, I'm new to Birthright as a 3.5 game. I only ever played the PC game, and wanted to try this out with regular D&D. I've been reading the pdf, and have gotten very confused by character creation. I was wondering if I could get some help

1- Chapter 1 and 2 each point to the other for the rules for determining the Blood Ability Score.

2- The Blood Ability Score is doubled and becomes the Bloodline Score? This is very, very confusing. First, the text refers to bloodline a number of times, does this mean the Ability Score or the Bloodline Score? When this number is increased, does the Ability Score increase? Are they independent after character creation? Why is a 12 in the Ability Score (a +1 modifier by D&D standards) become a 24 when doubled, which gives a +2 bonus?

3- How does Bloodline Strength interact with the abilities granted? Is being a Great blood, from a pure power standpoint, just better then Minor? Does the Bloodline Strength, the Scion class, or both determine what level of blood abilities you get to use?

Basicly, I find myself translating the rules differently each time I read them I'm not trying to bash, I'm just very confused. And my spelling sucks, sorry
