Starting at 5th level, you learn Charm Person. Charisma is your spellcasting modifier for this spell. You can only use this feature if the spell level you are casting it at is 1. You can use this a number of times equal to your Proficiency Bonus, and regain all uses of it on a long rest.

You learn the Cantrips: Minor Illusion, and Message.

You have a number of tails equal to the highest level spell you can cast (minimum of 1).

An orb ornament every kitsune has, it can be used as an arcane focus. The orb absorbs magical energy from the kitsune that owns it as part of their soul lives within. Once per long rest, the kitsune can draw on the orb to cast a spell that would otherwise require a spell slot without expending a spell slot. Any spell cast this way also does not require a vocal or somatic component. The maximum level spell that this can cast is 5th level

Should the orb be more than 30 ft away form the kitsune, they will gain 1 levels of exhaustion every day they are more than 30ft away from it. Re-entering its radius resets its exhaustion back to what it would be without this feature

Your Dexterity Score increases by 2, and your Charisma Score increases by 1
