Wall of Paper

You conjure up a wall of paper on the ground at a point you can see within range. You can make the wall up to 30 feet long, 10 feet high, and 10 feet thick, and it vanishes when the spell ends. It blocks line of sight but not movement. By using an action, holes can be punched through the paper allowing line of sight for anyone adjancent to the wall. The wall is immediately destroyed if it takes any fire damage.
