Source: Player’s Handbook
2nd-level transmutation
Casting Time: 1 action
Range: Self
Components: V, S
Duration: Concentration, up to 1 hour
You alter your physical form. Choose one of the following options. Its effects last for the duration during which you can take a Magic action to replace the option you chose with a different one.
Aquatic Adaptation. You sprout gills and grow webs between your fingers. You can breathe underwater and gain a Swim Speed equal to your Speed.
Change Appearance. You alter 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 (Slashing), fangs (Piercing), horns (Piercing), or hooves (Bludgeoning). When you use your Unarmed Strike to deal damage with that new growth, it deals 1d6 damage of the type in parenthesis instead of dealing the normal damage for your Unarmed Strike, and you use your spellcasting ability modifier for the attack and damage rolls rather than Strength.
