Improved Eldritch HeritageSource Ultimate Magic pg. 1 (Amazon)
The power of your discovered bloodline continues to grow.
Prerequisites: Cha 15, Eldritch Heritage, character level 11th.
Benefit: You gain either the 3rd-level or the 9th-level power (your choice) of the bloodline you selected with the Eldritch Heritage feat. For purposes of using that power, treat your sorcerer level as equal to your character level – 2, even if you have levels in sorcerer. You do not gain any of the other bloodline abilities.
Special: You may select this feat multiple times. Its effects do not stack. Each time you select the feat, it applies to a different bloodline power for that bloodline available at sorcerer level 3 or 9.
