Shapeshifting is a vastly underestimated magic considering how common it is. You have already done it so many times in your life. Utterly and completely changed your shape, I mean. Grew a limb back when your life had cut it off, sometimes a whole organ. Sprouted wings when you needed to fly. A mermaid’s tale when freediving in the deeper currents of your life. Inhabited the guise or form of another creature outside your own, to charm or to menace.
