Blessed Movement

A deity has blessed you with the power of free movement. This allows you to consciously use your movement to move in any direction, including up, without falling at the end of your turn. 

You are allowed to move into any space that is not already occupied or would otherwise restrict movement from passing. 

This means you could move up to a cave ceiling but could not pass the ceiling unless some other effect that would allow movement into that space is active for you. 

If you are not on a solid surface and become unconscious you will fall to the nearest solid surface.

With this feat you are never considered in zero gravity while you are conscious.
