Half-Succubi and Half-Incubi can live several centuries and never show any signs of aging after reaching adulthood at around age 16.

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. Half-Succubi and Half-Incubi experience frequent violent and sexual urges and visions, which can make it hard to resist their inherited evil.

Half-Succubi and Half-Incubi are about the same size as humans, though usually more slender and toned. Your size is Medium.

Your base walking speed is 30 feet.

Aside from their beauty, the best way to distinguish a Half-Succubus or Half-Incubus from all other tieflings is their small, leathery wings. While not as impressive as those of an actual Succubus, these wings are able to support stable flight at 50 feet each six seconds.

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.

You have resistance to fire damage.

Half-Succubi and Half-Incubi have different innate spellcasting than most tieflings due to their unique lineage. You know the thaumaturgy cantrip. When you reach 3rd level, you can cast the charm person 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 alter self spell once with this trait and regain the ability to do so when you finish a long rest. Charisma is your spellcasting ability for these spells.

You can speak, read, and write Common and Infernal.
