Wildwall

This spell creates a wall of multicolored lights that can be used defensively or offensively. You create a wall of multicolored lights up to 150 ft long, 60 feet high, and 2 inch thick--centered on a point you can see within range. The wall is a semi physical barrier and is impervious to all damage and effects less than the Wish spell. You can use an action to make it move at any point during the duration of the spell, though once moved it will continue to perpetuate the movement for the duration of the spell and the movement cannot be changed later. If you cause it to move in a straight line it will move forward at a rate of 60 ft per round. If you cause it to spin it revolves at a rate of one revolution per round. If a creature tries to pass through the wall they must attempt a DC 22 STR save otherwise, it is moved along with the wall’s movement. The wall damages structures while passing through them as if they weren’t there.

Any creature or object that touches the wall takes 9D6 Force damage, a creature can only take one instance of this damage each turn. Each time a spellcaster touches the wall and has a spell that is active they trigger a Wild Magic Surge. Each time a magic item that uses charges touches the wall one charge is expended and it triggers a Wild Magic Surge.
