As you walked through the forest you slowly began to hear the voices of other people. Not wanting to be seen you crouch down and moving slowly you move towards the move, still making some noise as you walk towards the sounds.
There were two voices. One female and one male. Slowly the voices grow closer and you eventually see two hikers emerge from a path. They were teenagers about your age, one was a tall brown haired guy who had his arm around a shorter blond female. You didn't recognize them though you feel as if you might've of seen them occasionally at school.
Suddenly an idea pops into your mind and you grab the Book Of Myths from you satchel and begin to choose what spell to cast on them.
You open the Book of Myths and pointing a finger at the male, you whisper the word "Shift".
The two were still talking when the transformation began.
"Yeah, we should go meet up with Jake after-"
Suddenly the male lurched forward nearly collapsed on the ground. The girl instantly panicked and started trying to calm the guy down.
Immediately thick brown fur started to grow rapidly on the man's body, his chest being covered by the fur in seconds. Next two large horns started appearing on his head, his muscles started bulging heavily as his shirt ripped apart to reveal a set of abs. His shoes nearly exploded as his feet were replaced by two cloven hooves and his pants were torn to shreds, revealing his massive manhood covered in a thick brown fuzz.
To top off the transformation, the teenager grew a large snout and gave off a large roar that would scare off all wildlife for about a two days. He had become a full blown Minoraur.
The girl who was at first trying to help her friend suddenly screamed, she stood in place in fear as she watched her friend become a monster.
The Minotaur looked at the girl and gave a confused expression. "Whoa what's wrong, why'd you scream?" said the Minotaur still not realizing what had happened yet.
The girl didn't respond and instead ran off, ignoring the cries the cries of concern the Minotaur gave off.
The Minotaur looked at his hands and then his entire body as he realized what happened. He started panting heavily as the gravity of the situation set on him. He gave another massive roar and started running off towards the direction the girl had gone through.
You suddenly panicked and before the Minotaur could disappear into the bushes you immediately reversed the spell sending the Minotaur tumbling into his human form.
You could hear a faint sobbing as you left the woods. It had been a great test, though now you've realized not to take your powers lightly.
