Kitsune Bloodline

The story of it's origin is unknown, but a few words are spread around the world. A long long time ago, a selected few females got the blessing of the Goddess Inari. Those females were foxes, with her blessing the animals became filled with magic. Not only that but those foxes turned into Yokai. Those first foxes had the power to shapeshift, with a liking to assume the form of a human, but there would always be a failure, be it showing their animal feet, eyes, fur, ears or tail. Trough the years they managed to polish their powers, but be it pride or maybe faith at some point they stopped trying to look like a human. They kept their antrho form and other human like features, but they keep showing their ears and tails. As years passes and new generations are born two interesting things happen. It's found out that for some reason only females are born from a Kitsune. The other thing is that evolution made so the daughters of Kitsunes were actually born as Humans with animal features, just like the form their mothers were when they got pregnant and conceived their children. The new genaration managed to get the same magic their mothers did and their shapeshifiting lost some of  it's power. While one blessed by Inari can turn into anything, a descendant can only go to it's roots, their fox form, and into it's humanoid form. The descendants also can only make female Kitsunes.

Elemental Affinity

Starting at 6th level, when you cast a spell that deals damage of the type associated with your Kitsune ancestry, you can add your Charisma modifier to one damage roll of that spell. At the same time, you can spend 1 sorcery point to gain resistance to that damage type for 1 hour.

Necrotic Resistance

 

At level 14 your Yokai side starts to get stronger, making you resistant to necrotic damage.

Kitsune Presence

Beginning at 18th level, you can channel the dread presence of your bloodline's ancestors, causing those around you to become awestruck or frightened. As an action, you can spend 5 sorcery points to draw on this power and exude an aura of awe or fear (your choice) to a distance of 30 feet. For 1 minute or until you lose your concentration (as if you were casting a concentration spell), each hostile creature that starts its turn in this aura must succeed on a Wisdom saving throw or be charmed (if you chose awe) or frightened (if you chose fear) until the aura ends. A creature that succeeds on this saving throw is immune to your aura for 24 hours.
