Controlling Companions, Familiars and Followers

Source Ultimate Campaign

In a typical campaign, each player controls one character. However, there are several ways for you to temporarily or permanently gain the assistance of a companion, such as an animal companion, a cohort, an eidolon, or a familiar. The combat advantages of controlling a second creature are obvious, but having a companion also has drawbacks and requires an understanding of both your role and the GM’s in determining the creature’s actions. This section addresses common issues for companions and the characters who use them.

How a companion works depends on the campaign as well as the companion’s nature, intelligence, and abilities. In some cases, the rules do not specify whether you or the GM controls the companion. If you’re entirely in control, the companion acts like a subsidiary PC, doing exactly what you want just like a true PC. If the GM is control, you can make suggestions or attempt to influence the companion, but the GM determines whether the creature is willing or able to attempt what you want.
