A 5-foot thick, 10-foot tall, vibrantly colored, and bushy hedge wall appears in a ring at the edge of a 15-foot radius centered on a solid surface of your choice for the duration. The hedge lightly obscures anything being viewed through it, and a creature moving through its space must expend an extra 2 feet of movement for every foot it travels. If any portion of the hedge is not supported by a solid surface, that portion vanishes early, leaving a gap in the ring.   Each creature completely inside of the ring adds +1 to its AC and saving throws. Until the spell ends, you can use a bonus action to thicken the hedge, heavily obscuring anything seen through it until the start of your next turn.
