Domain Companion (open to other names): Because of your connection to animals through your deity, you have attracted a devout animal follower.
Prerequisites: Animal Domain, Charisma 12+, character level 4+
Benefits: The cleric gains an Animal Companion as per the rules in the PHB. For determining the powers and abilities of the animal, divide the cleric's level by two. If the cleric has another class that grants an animal companion, she does not gain a second companion. Rather, the levels for the two classes stack in whichever way gives the greater benefit to the animal.
