Spawn of Pazuzu (3.5e Feat)
From D&D Wiki
Spawn of Pazuzu [Abyssal Heritor, Aerial]
You have a hereditary link to the Prince of the Lower Aerial Kingdoms that causes your wings to grow much larger, giving you an increased fly speed.
Prerequisite: Fly speed, poor maneuverability, Vestigial Wings, Functional Wings, Fiendish Flight
Benefit: Your current fly speed is doubled.
Special: Because your wings are so large, armor must be made, or remade if the armor was looted, to fit them, doubling it's cost.
