When the War of the Red Son happened and Demons waged war on our plane, some of them sought to leave a piece of themselves behind, leading to the creation of Tieflings. Looked down upon by the older Races and feared by the general populace, it is hard for a Tiefling to make their way in life. For a player they can choose Tieflings as a playable race using the stats below:
Ability Score Adjustment: Your Dexterity score increases by 2, and your Intelligence score increases by 1.
Age: Tieflings mature at the same rate as humans but live a few years longer.
Alignment: Tieflings might not have an innate tendency toward evil, but many of them end up there. Evil or not, an independent nature inclines many tieflings toward a chaotic alignment.
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 abyssal 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.
Devil’s Tongue: You know the vicious mockery cantrip. When you reach 3rd level, you can cast the charm person spell as a 2nd-level spell once with this trait. When you reach 5th level, you can cast the enthrall spell once with this trait. You must finish a long rest to cast these spells once again with this trait. Charisma is your spellcasting ability for these spells.
Languages: You can speak, read, and write Common, and Abyssal.
