I would bring…

Infinite wishes so I could survive up there with drinks and food for as long as I lived .

I would also bring pet ant’s that X100 size if your in danger they also could fly with the wishes.

A magic clock that could send you back in time or forward incase of a disaster.

Also some dust so you can teleport if the clock did not work.

A map that could navigate you anywhere by turning into gloves to drive the air ship to where you need to go to.

I would take a sword that can break threw anything just incase I got stuck in a room I could smash threw the door.

I would also take a sleeping-bag that just needs a button to be pressed and heats as soon as its pressed .

I would take clothing that washes it self and turns into a waterproof coat witch is extremely warm for extreme altitude.

I would bring a magic table that projects your next mission out it  and calls from family.

I would also bring different dust if the clock and natural dust don’t work at all so it would send you straight to the top.
