This feat allows you to acquire a powerful familiar, but only when you could normally acquire a new familiar.
Prerequisites: Ability to acquire a new familiar, compatible alignment, sufficiently high level (see below).
Benefit: When choosing a familiar, the creatures listed here are also available to you. You may choose a familiar with an alignment up to one step away on each alignment axis (lawful through chaotic, good through evil).
Improved familiars otherwise use the rules for regular familiars, with two exceptions: if the creature's type is something other than animal, its type does not change; and improved familiars do not gain the ability to speak with other creatures of their kind (although many of them already have the ability to communicate).
1 Or other celestial, entropic, fiendish, or resolute animal from the standard familiar list.
