Your familiar grows in power and abilities as you increase your eldritch knight level.
Benefit: Your levels in the eldritch knight class stack with levels in classes which grant the arcane bond (familiar) class feature for purposes of determining the power of your familiar. In addition, when you take this feat, increase one of your familiar’s physical ability scores by 2. Treat this increase as a normal ability score increase gained through level advancement.
