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.
Infernal Legacy. You know the thaumaturgy cantrip.
Once you reach 3rd level, you can cast the hellish
rebuke spell once per day as a 2nd-level spell. Once you
reach 5th level, you can also cast the darkness spell
once per day. Charisma is your spellcasting ability for
these spells.
Languages. You can speak, read, and write Common and Infernal.
