Elodara's Scintillating Shroud

You create a swirl of shimmering smoke that envelops a creature's space within range. The creature is unable to see their surroundings and must make a Wisdom saving throw while in the shroud. On a failed save, the creature becomes charmed for the duration. While charmed by this spell, the creature is incapacitated and has a speed of 0. The creature can make save again at the each of its turns, escaping the charm on a success. The shroud remains until the caster loses concentration, and the enshrouded creature can leave the shroud by leaving the space they were previously in.
