The Eldritch Scion archetype is supposed to grant the character a Bloodrager bloodline. However, this Ability Pool doesn't appear.
Speculation: The Bloodline archetype feature in acg_abilities_class.lst has the following: BONUS:ABILITYPOOL|Bloodrager Bloodline|1. However, the actual Bloodrager class uses BONUS:ABILITYPOOL|Bloodline|1 to add bloodline options.
