Taking the book in hand, you think about which spell you could try first. Maybe not any summoning spells right now. The noise might have the neighbors asking questions.
And you definitely don't want to summon any of the big ones either!
You skim the pages of the book until you come across a page for monster shifting. Like the summons, they also have levels of power, from Lesser to Legendary and Divine.
Ever since you were a little girl you wondered what it would be like to transform into another creature. And now, you finally get to live out those fantasies for real!
As cool as it would be to become a dragon or something like that, you feel that it's best to start small before working your way up.
With the tome in hand you thought of the creature you wish to become, and uttered the command: "Lesser Shift!"
