Children of the Night

You know the Find Familiar ritual, but your familiar must take the form of a Bat, Giant Rat, Rat, Raven, or Wolf.  Once per day, you may expend one hit die rather than spending the material component when casting this ritual.  Unlike the standard Find Familiar version, you may command your familiar to attack as a bonus action. You may also telepathically communicate with these creatures and their giant/dire varieties. At 3rd level you learn the Summon Beast spell, and may cast it once per day. At 5th level you may Wild Shape (as per the Druid Ability) into the form of one of these animals by expending a hit dice. After you have used this ability you must perform a short or long rest to use it again.
