You have the ability to use Wild Shape on your turn as a bonus action, rather than as an action.
Additionally, while you are transformed by Wild Shape, you can use a bonus action to expend one spell slot to regain 1d8 hit points per level of the spell slot expended.
The rites of your circle grant you the ability to transform into more dangerous animal forms. At 2nd level, you can use your Wild Shape to transform into a beast with a challenge rating as high as 1. You ignore the Max. CR column of the Beast Shapes table, but must abide by the other limitations there.
Starting at 6th level, you can transform into a beast with a challenge rating as high as your druid level divided by 3, rounded down.
Change Appearance. You transform your appearance. You decide what you look like, including your height, weight, facial features, sound of your voice, hair length, coloration, and distinguishing characteristics, if any. You can make yourself appear as a member of another race, though none of your statistics change. You also don't appear as a creature of a different size than you, and your basic shape stays the same, if you're bipedal, you can't use this spell to become quadrupedal, for instance. At any time for the duration of the spell, you can use your action to change your appearance in this way again.
Natural Weapons. You grow claws, fangs, spines, horns, or a different natural weapon of your choice. Your unarmed strikes deal 1d6 bludgeoning, piercing, or slashing damage, as appropriate to the natural weapon you chose, and you are proficient with you unarmed strikes. Finally, the natural weapon is magic and you have a +1 bonus to the attack and damage rolls you make using it.
You have learned to use magic to alter your physical form in more subtle ways. You can cast the Alter Self spell at will.
You assume a different form. When you cast the spell, choose one of the following options, the effects of which last for the duration of the spell. While the spell lasts, you can end one option as an action to gain the benefits of a different one.
Aquatic Adaptation. You adapt your body to an aquatic environment, sprouting gills, and growing webbing between your fingers. You can breathe underwater and gain a swimming speed equal to your walking speed.
