Wall of Spores

You conjure up a wall of dense, fungal spores 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. The wall vanishes when the spell ends. Creatures are able to walk through the wall, but it counts as difficult terrain. Any creature of your choice that starts its turn within or enters the wall must make a CON saving throw. On a failure, the creature becomes Poisoned.

A creature poisoned in this way has its AC reduced by 2 and becomes disorientated. While disorientated, whenever it uses its movement, it must roll a D4, where 1 is North, 2 is East, 3 is South, and 4 is West (you may use a D6 for Hexagonal boards). The creature MUST use the half of its movement speed to move in that direction. A creature that ends its turn outside of the wall may repeat its saving throw.
