As a Bonus Action, you shape-shift into a Beast form that you have learned for this feature.
You stay in that form for a number of hours equal to half your Druid level or until you use Wild Shape again, have the Incapacitated condition, or die. You can also leave the form early as a Bonus Action.
Number of Uses: You can use Wild Shape twice. You regain one expended use when you finish a Short Rest, and you regain all expended uses when you finish a Long Rest.
Known Forms: You know four Beast forms for this feature, chosen from among Beast stat blocks that have a maximum Challenge Rating of 1/4 and that lack a Fly Speed. Whenever you finish a Long Rest, you can replace one of your known forms with another eligible form.
When you reach certain Druid levels, your number of known forms and the maximum Challenge Rating for those forms increases, as shown in the Beast Shapes table. In addition, starting at level 8, you can adopt a form that has a Fly Speed. When choosing known forms, you may look in the Monster Manual or elsewhere for eligible Beasts if the Dungeon Master permits you to do so.
