When determining your character’s ability scores, increase one score by 2 and increase a different score by 1, or increase three different scores by 1. Follow this rule regardless of the method you use to determine the scores, such as rolling or point buy. The “Quick Build” section for your character’s class offers suggestions on which scores to increase. You can follow those suggestions or ignore them, but you can’t raise any of your scores above 20.

Tieflings mature at the same rate as humans but live a few years longer.

Tieflings are about the same size and build as humans. Your size is Medium.

Your base walking speed is 30 feet.

You can speak, read, and write Common and one language of your choice. Most commonly this will be Infernal – a harsh and alien language spoken by the Baatezu, devils of the Nine Hells.

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.

Your infernal heritage grants you resistance to your choice of acid, cold, fire or poison damage.

Your infernal legacy grants you a choice of powers that originate with your bloodline.

Alluring Ingenuity

You have proficiency in Charisma (Persuasion) plus one other Charisma, Intelligence or Wisdom skill of your choice.

Devil's Own Luck

When you fail an ability check or saving throw, you may choose to succeed instead. Once you have used this feature you may not do so again until you have completed a long rest.

Magic

Infernal magic flows through your blood, enabling you to cast one cantrip of your choice at will. When you reach 3rd-level you gain the ability to cast one 1st-level spell of your choice. When you reach 5th-level you also gain the ability to cast one 1st- or 2nd-level spell of your choice.

You may cast each spell that you know once at 2nd-level using this trait, regaining the ability to do-so when you complete a long rest. You may also cast these spells using any spell slots you have. Your spellcasting ability for these spells is Intelligence, Wisdom, or Charisma (choose when you select this race).

You may choose your spells from the following based upon your Infernal Resistance:

Unsettling Aura

You have proficiency in Charisma (Intimidation).

Starting from 5th-level, as an action on your turn you may choose any number of creatures within 30 feet to take a Wisdom saving throw (DC 8 + your proficiency bonus + your Charisma modifier). A creature automatically succeeds if it cannot see or hear you. On a failure a creature is frightened of you for up to one minute. A frightened creature may repeat the saving throw at the end of each of its turns, ending the effect upon itself on a success. You may use this action a number of times equal to half your proficiency bonus, regaining all spent uses when you complete a long rest.

Winged

A pair of bat-like wings sprout from your shoulder blades as a visible sign of your infernal legacy. So long as you are not wearing heavy armor, your wings grant you a flying speed of 30 feet.

Tiefling Variants

Should you wish to recreate the Tiefling variants from the now discontinued Mordenkainen's Tome of Foes, you may use the following recommendations. To also recreate the older fixed ability score increases, choose to increase two scores (+1/+2) entering the suggested ability score first (+1) and Charisma second (+2).

Each variant represents a Tiefling with a suggested patron, and with ties to a particular realm within Baator (the Nine-Hells) or one of the layers of the Tartarian Depths of Carceri (also known as Tarterus).

*D&D Beyond Support

Note that due to public homebrew spell limitations, the following options from the Mordenkainen's Tome of Foes Tiefling Variants had to be removed or replaced; friends, armor of agathys, ray of sickness, searing smite, and crown of madness.
