This trait is one of the most confusing and IMHO messed up traits in the game.
There are so many unanswered questions about how it work.
1. There are 50 Kerensky Bloodnames (not sure if any have been reaved but I would not think so) are all of them Level 13 or just some.
and the fact that most of the known Bloodname cant be gained by players.
I think the Kerensky ones should be Rank 13. Even if they're sort of tarnished from some actions, they're still Kerensky bloodnames, and are going to be quite prestigious and game changing. They're such an advantage that characters starting out with them can really skew things.
Also keep in mind the chart doesn't prevent your from gaining those bloodnames, you just can't start with them.
2. Why would I pay 300 xp to have a reaved Bloodname.
A reaved Bloodname is simply a Bloodname that has had its count lowered. It no longer has the full 25 count, so your bloodhouse has lost prestige. It isn't like Wars of Reaving where the entire name has been eliminated.
3. Why would I pay anything for a Bloodname I may never get through play.(with title you only pay if you have a title not if you think you my be a Duke sometime in your career)
This..is a big issue I think. You do realize that if you've paid 300 XP to have Bloodname at +3, that means you START with the Bloodname? You don't have to earn it later on, you already have gone through the Trials of Bloodright. Read page 127. Its not totally clear, but if you read it closely you'll see that you have the name.
4. How do you determen what Bloodnames are worth what points is there a chart somewhere, and I'm not talking about the general Bloodname charts in the clan books. they only show what Bloodnames are general and which ones are phenotype.
Good question. I'm honestly not sure :) The back of ATOW gives some examples, but I'm not sure if there's anything that specifically says "This is this kind of bloodname." Maybe Ask the Writers?
5. There seems to be no diffrents between having the Bloodname and having the bloodline in the game?
Again, if you have the Bloodname Trait, you already have the Bloodname, while your Bloodline is just who you descended from, and will eventually trial for.
6. Since Bloodnames are matrilineal when did this start and if it started right away how are the any Kerenskys both founders were male. (goes for most Bloodnames)
It most likely started when the Iron Wombs took off. The Clan scientists would've been able to fiddle with things to make the Kerensky DNA the matrilinial contributor.
I'm trying to get a clan game started and after reading through the Bloodname rule most of my players are less then happy with them is why I'm here asking these questions.
So any help would be welcomed.
They're a little odd and lacking in information, but I think the biggest thing you're missing is that if you have the Bloodname Trait, then you have already gone through your Trial of Bloodright, and you HAVE the Bloodname.
