Races that are not Large nor have an innate flying speed gain an extra Feat of their choice. This Feat must be a "Full Feat".

Your character can speak, read, and write Common and one other language that you and your DM agree is appropriate for the character. 

You gain 3 ability points to increase any abilities of your choice. You can't increase a single ability by more than 2 with these points.

You can cast the detect magic and disguise self spells with this trait. When you use this version of disguise self, you can seem up to 3 feet shorter or taller. Once you cast either of these spells with this trait, you can’t cast that spell with it again until you finish a long rest.

You use your Spell Save DC or Mastery Save DC (your choice) for these spells. If you have a class feature that allows you to learn spells, you count these spells as known by that class. You always have them learned or prepared, and they don’t count against the number of spells you can learn or prepare.

As a bonus action, you can magically turn invisible until the start of your next turn or until you attack, make a damage roll, or force someone to make a saving throw. You can use this trait a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a long rest. 

You count as one size larger when determining your carrying capacity and the weight you can push, drag, or lift. 

You have the ability to communicate in a limited manner with Beasts, Plants, and vegetation. They can understand the meaning of your words, though you have no special ability to understand them in return. You have advantage on all Charisma checks you make to influence them.
