Benefit

You can obtain a familiar in the same manner as a sorcerer or wizard, but it possesses the dark template. As with a sorcerer or wizard, obtaining a familiar takes 24 hours and uses up magic materials worth 100 gp. For the purpose of determining familiar abilities that depend on your arcane caster level, your levels in all classes that allow you to cast mysteries or arcane spells stack.

Special

if you gain access to an alternative fa mi I iar, such as through the Improved Familiar fear, it also gains the dark template.
