I broke down and bought the new Legacy of Dragons book... and truth be told, I've been wanting to create a Dragon Disciple PFS. When looking at my options, it looks like the Imperial Dragon (Sovereign) with Imperial, but then I realized that Crossblood says something. It says:
A crossblooded sorcerer gains the bloodline arcana of both her bloodlines.
Does that mean Crossblooded "alters" the Arcana Bloodline for the player, and therefor cannot be used in conjunction with the bloodline varients?
It sucks to, because I wanted to be an Imperial Imperial Dragon Bloodline and use something to give me intimidation when I case spells...
It does, because normally you only get one bloodline arcana.
