I'm wondering how often I can use Familiar Form per day. The duration is clear but can I use the hex multiple times per day each with a level-minutes durations? Can I use it in 1-minute intervals with a maximum of level-miutes?
At 8th level, a beast-bonded witch may take the shape of her familiar (or a giant version of her familiar or a similar kind of animal) as if using beast shape II. For example, a witch with a rat familiar can turn into a Tiny rat, Small dire rat, or a larger rodent; one with a cat familiar can turn into a Tiny cat or a Large feline such as a tiger or lion; one with a monkey familiar can turn into a Tiny monkey or a Large gorilla, and so on. The witch can remain in animal form for a number of minutes per day equal to her level. This ability replaces the witch's 8th-level hex.
