You uncover secrets to connecting more fully with your animal companion or familiar from studying another type of magic.
Prerequisite: Ability to gain a familiar, ability to gain an animal companion.
Benefit: Choose a familiar or companion you already have. When determining the abilities of your chosen familiar or animal companion, you can combine the levels of your spellcasting classes that grant either an animal companion or a familiar. For example, a 4th-level druid/3rd-level sorcerer can grant his familiar all of the abilities that a familiar of a 7th-level sorcerer would normally have.
Special: You can gain this feat multiple times. Its effects do not stack. Each time you take the feat, it applies to a different familiar or animal companion.
