You become briefly ethereal and intangible. For the duration, you can move in any direction and do not fall. You can move through creatures, objects, walls, terrain, and effects as if they were not there. You can only pass through magical objects if they do not block ethereal transit. While you are intangible, you are immune to all damage besides force damage. At the start of your next turn, you once more become tangible, manifesting in your current space. If the space is occupied, you are shunted to the nearest unoccupied space, take force damage equal to twice the number of feet you are forced to move. If the space you manifest is not on the ground and you cannot fly, you fall to the ground.
