Dust Form

You transform into a cloud of moving dust. You remain in your dust form until you use your action to dismiss the spell. During this time, you can move in any direction. If you move up or down, every foot of movement costs an extra foot. You can see and hear around you, but everything there looks sepia, and you can't see anything more than 60 feet away.

You ignore all objects, allowing you to move through objects you'd be hindered by if you were in your physical form.

When you end the spell, you immediately return to your physical form in the spot you currently occupy. If you occupy the same spot as a solid object or creature when this happens, you are immediately shunted to the nearest unoccupied space that you can occupy and take force damage equal to twice the number of feet you are moved.
