Aoth's Lift

You choose a 10 foot radius cylinder with a height that reaches the ceiling within range and imbue it with gravity altering energy, when a creature steps into the area and speaks a password (chosen by you), the magic lifts them at a rate of 15 feet per round until they reach the ceiling, once they step off, the gravity altering no longer affects them. If they say the password while within 5 feet of the spell’s area, they can step out onto the effect, which then lowers them at a rate of 15 feet per round. This spell has no effect if there is no ceiling above the area in which it is being cast.
