You slide the subject creature along the ground a distance of up to 20 feet in any direction. (If the creature is flying or otherwise not on the ground, it moves parallel to the ground.) You can’t slide the subject to end movement in a space that is occupied by an ally, an enemy, or a solid object; if you attempt to do so, the spell automatically ends. You can slide a creature through a square occupied by an ally as long as you do not end movement there, as normal. You cannot slide the subject up or down, but you can slide it over the edge of a cliff or other drop-off if you desire.
This movement does not provoke attacks of opportunity.
