Bonded feats deal with any creature bonded to you through the arcane bond, divine bond, or nature’s bond class abilities. Bonded creatures advance based on your character level, thus your level in associated classes is used as a prerequisite to take many of these feats. For example, a prerequisite of “bonded creature 10th-level” would require you to possess ten levels in a class which grants a bonded creature (such as ranger, wizard, or paladin) and for you to have chosen the animal companion, familiar, or mount options granted by this class. Either a character or a bonded creature may take a bonded feat. If you have multiple classes which grant bonded creatures, you must select one creature to benefit from any bonded feat you or your bonded creature take.
