Tiefling

To be greeted with stares and whispers, to suffer violence and insult on the street, to see mistrust and fear in every eye: this is the lot of the Tiefling. And to twist the knife, Tieflings know that this is because a pact struck generations ago infused the essence of Asmodeus, overlord of the Nine Hells (and many of the other powerful devils serving under him) into their bloodline. Their appearance and their nature are not their fault but the result of an ancient sin, for which they and their children and their children's children will always be held accountable.

Creating a Tiefling

Ability Score Increase. Your Charisma score increases by 2.
Age. Tieflings mature at the same rate as humans but live a few years longer.
Size. Tieflings are about the same size and build as humans. Your size is Medium.
Speed. Your base walking speed is 30 feet.
Darkvision. Thanks to your infernal heritage, 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.
Hellish Resistance. You have resistance to fire damage.
Languages. You can speak, read, and write Common and Infernal.

Racial Options

There are a few options to make your character fit the ideas you may have. The Ability Score Increase, Size, and even Languages can all be customized to better fit your character's history. Maybe you come from a very hardy people, like the Dwarves, but your character can't handle even the slightest cold breeze, but they make up for it with their incredible intellect. You could have been born of the tall and long Elves, but you find yourself barely coming up to some of their hips. Your Goblin may have been adopted by a couple of loving Genasi and they taught you to speak Primordial instead of Goblin. The options listed under your chosen race are just suggestions to easily fit your character within their culture's society, but you can change things up to make your character truly yours. There may be limitations set by the DM; rarely will you find a Large Fairy or a Tiny Goliath, but if you have a good story-driven reason for different character options, anything can be possible. Below are open-ended options for customizing your race.
Ability Score Increase. Increase one ability score by 2, and increase a different one by 1.
Size. Your size is within one size option of your race's average size.
Languages. You can speak, read, and write Common and one other language that you and your DM agree is appropriate for the character.
