Names

Many awakened creatures take on the name they were referred to while they were "pets."  Others shake off their old name and adopt a new one.

Still a Creature

Despite being granted intelligence and the ability to speak, in general you still have the same shape, form, and size as the animal or beast you began life as.

Limited Manipulation

Your talons aren't very good at picking up and manipulating things designed for humanoids.  You will find it difficult to manipulate objects that have been created for a humanoid-centered world, but feel free to get clever with how you get things done.  The GM shouldn't let this limited manipulation hinder you too much if you come up with ideas on how to overcome it.  You should be equally able to interact with the world around you as other player characters.

Ability Score Increases

Choose one Ability Score to increase by two, and another to increase by one, based on the traits that best exemplify the animal you awakened from:  strong, fast/agile, tough, smart, wise, influential.

Age

The magic that you've been imbued with has granted you more than just intelligence; it has also granted longevity.  Awakened creatures tend to live at least twice as long as their unawakened cousins.

Alignment

Awakened creatures typically share the values of their awakener (if there is one), though this is not true in all cases.  With a fresh perspective of existence, you're free to choose your outlook on life.

Size

Creatures come in all shapes and sizes.  There are no mechanical changes for Small and Medium characters, but there are cases where you might be Smaller than small or larger than Medium depending on your origin creature.  Be sure to clear this with your GM before selecting them.

Tiny:  You count as one size smaller when determining your carrying capacity and the weight you can drag or lift.  You can share the same space as an ally.

Large:  You count as one size larger when determining your carrying capacity and the weight you can push, drag, or lift.  When casting spells that emanate from your body/position, treat it as if you are Medium-sized, with the spell origin coming from a single, 5-foot square, typically where your head is.

Languages

The blessing of awakening grants you the ability to speak and read Common in addition to the language of your awakener.  You are also capable of writing if your physical form allows it.

Animal Form

As an animal you had no need to use weapons.  Thus, you are not proficient with any weapons granted by your class.  Instead you are only proficient with your natural weapons.  you are still proficient with the armor provided by your class.

Upon reaching 5th level, your natural weapons count as magical weapons.

Bird's Eye View

You have proficiency in the Perception skill.

Diverse Features

At 1st level you begin with two features from the Diverse Features list.  In addition, you get to pick a single Diverse Feature at both 5th and 10th level.  You can also choose a Diverse Feature instead of a feat.

You can sense in invisible force lines (magnetic field lines or ley lines) of the world, so you always know your facing and approximate latitude and longitude.

Your bite attack does an extra die of damage.

You can spend half your movement speed to hover.

You gain proficiency with Perception and Survival skills.

Accustomed to darkness, you have superior vision in dark and dim conditions.  you can see in dim light within 60 feet of you as if it were bright light, and in darkness as if it were dim light.  You can't discern color in darkness, only shades of gray.

You have learned how to make focused strikes to hinder your foes.  If you bit a creature with a weapon attack, you can use your bonus action to use the Help action on an ally within 10 feet of you.

You have advantage on Strength (Athletics) checks made to grapple.
