Homebrew Half-Elf Tiefling Species Details

A Half-Elf Tiefling almost looks like a normal half-elf for most of its childhood. The only visible abnormality is unusual coloured irises, usually a vivid hint of what's to come. Once a Half-Elf Tiefling reaches maturity their Tiefling nature comes to the fore with the vivid colour of the irises overtaking the entire eye, along with a variety of other demonic traits manifesting. This can include the development of horns, elongating of teeth, growth of a prehensile tail, or morphing of feet to hooves. Not all of these changes are guaranteed with the end result being as varied as in normal full Tieflings.

+2 Charisma, +1 Intelligence, Darkvision, Fey Ancestry, Skill Versatility, Hellish Resistance, Infernal Legacy

Ability Score Increase

Your Intelligence score increases by 1, and your Charisma score increases by 2.

Darkvision

Thanks to your infernal/elf blood, 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 colour in darkness, only shades of grey.

Hellish Resistance

You have resistance to fire damage.

Infernal Legacy

You know the thaumaturgy cantrip. When you reach 3rd level, you can cast the hellish rebuke spell as a 2nd-level spell once with this trait and regain the ability to do so when you finish a long rest. When you reach 5th level, you can cast the darkness spell once with this trait and regain the ability to do so when you finish a long rest. Charisma is your spell-casting ability for these spells.

Fey Ancestry

You have advantage on saving throws against being charmed, and magic can’t put you to sleep.

Skill Versatility

You gain proficiency in a skill of your choice.
