Eric's Enchanted Elevator

When this spell is cast, a pair of lift doors open in the air after a minute. this lift can carry 4 small or medium creatures, 16 tiny creatures or one large creature, along with their luggage and 1d6+your spellcasting modifier+10 lbs of extra weight (minimum of 10lbs). inside the lift are a group of 6 buttons; a close door button that does nothing, an emergency button that teleports the lift to a random safe place of the dm's choice, a stop button that keeps the doors open for 1d10 minutes and 2 buttons that can teleport the lift up to 2 locations of the casters choice. the lift doors close 30 seconds after the caster has gotten in, and after the caster has chosen what locations the lift will end up in. the lift can stop at any location the caster knows about and has seen. when the lift is moving, the occupants feel like they're moving upwards, no matter which direction they're going. The journey lasts for a minute, and annoying music is playing all along. when the lift arrives at its first destination, the doors open for 30 seconds, unless the caster steps out, in which case the doors will stay open. when the lift reaches its final destination, the lift will stay open until it is fully empty. the buttons cannot be used without someone re-casting the spell. when the lift is empty, the dors close and then vanish.
