Your diminutive size won't stop you from being the life of the party. I mean, who doesn't love fairies?

You have disadvantage with athletics (STR) checks but have advantage on persuasion (CHA) checks. 

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. Once you use this trait, you can’t use it again until you finish a short or long rest.

You have the ability to communicate in a limited manner with beasts and plants. 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.

From your connection and exposure to the fey wilds, you can cause nature to do some fun things. You know the Druidcraft Cantrip.

Your Charisma score increases by 2 and, either, your Wisdom or Dexterity Score increases by 1.

Fairies age very rapidly reaching full maturity in little over 4 years. However, they can live for centuries with older looking fairies being incredibly rare. When a Fairy dies of natural causes such as old age their bodies turn into fairy dust and become one with the fey wilds once more. 

Fairies love freedom, variety, and self-expression, so they lean strongly toward the gentler aspects of chaos. They value and protect others’ freedom as well as their own, and they are more often good than not. Fairies are playful and fun loving, just s likely to help a weary traveller as they are to play a trick on him. 

You can use your fairy dust to resize any non-living equipment to suit your needs. You can spend 1 hour, or a short rest, coating the equipment in your fairy dust, slowly shrinking it to fit your body. This effect is permanent on non-magical items.

Fairies range from 3-10 inches tall. Your size is Tiny.

Your base walking speed is 10 feet. You have a flying speed of 30 feet with a hover height of 10 feet. If you end your turn higher than 10 feet you slowly fall until you are within 10 feet of the ground.

Accustomed to twilit forests and the night sky, 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 advantage on saving throws against being charmed, and magic can’t put you to sleep.

You can speak, read, and write Common and Sylvan.
