At page 55 for the draconic bloodline, there is the trait 'True Dragon', which grants Reptilia Bloodline 2. Usually, the Reptilia Bloodline X ability has an associated lineage mentioned. Like the above Draconic Bloodline, granting Reptilia Bloodline 3 - Draconic.
Since 'True Dragon' doesn't mention any lineage in specific, does that mean you can pick any 2 traits of any lineage you'd like, or is it still restricted to draconic?
The ability specifically says "having this trait unlocks additional bloodline traits within this lineage allowing a model to have X Bloodline Traits."
So it would mean that you have to remain within the Bloodline for your bonus traits.
Huh, good call. I was gonna point out monsters don't specify a bloodline but they all say "Reptilia Hybrid". At the very least its going to follow the unlocks of the reptilia, IE since you don't have saurian bloodline it takes 2 1st traits to get a 2nd tier one though if you already had two 1st tier traits from your species. Hmm. I may have to look into messing with that on my reptilia faction if it turns out to be just "any reptilia trait". I can see it being any, actually, because all the reptilia is descendants from the Great Leviathan.
