Tower Magic is a type of magic used by Rapunzels. Its name refers to Rapunzel's prison while the ivies it conjures may refer to the ivies that covered the tower.
Rapunzels can summon and control long vines covered in ivy and flowers. They can use these vines like ropes and bungee ropes to get in and out of places. Rapunzels can also make constructs out of ivy like beds and gazebos. Sometimes, the ivy can form cages, as shown in 'Rose's Fairy Tale Collection'. Magic ivy can also be used to lift off or boost others into the air. In episode 13, 'The Grand Ball', Astoria grew a small forest of ivy which pushed rampaging donkeys off the ballroom floor.
