Great Bene Ajna

Delving deeper into the natural magic inherent within their race, a Grahanox is able to access more magical spells, and is often a strong indicator that the Grahanox is a natural born Sorcerer.  You learn the Command spell and can cast it at will, without expending a spell slot. You also learn the Invisibility and Darkness spells, each of which you can cast once without expending a spell slot. You regain the ability to cast the spell in this way when you finish a long rest.  Charisma is your spellcasting ability for these spells
