Enthrall (variant)

You begin to talk nonsensically while imbuing your words with magic, drawing attention and causing a distraction. Creatures of your choice that can hear you and that you can see within range must make a Wisdom saving throw. If you or your companions are fighting a creature it has advantage on this save, and any creature that can't be charmed succeeds automatically. On a failed save, a target has a -10 penalty to Perception checks and to Passive Perception when trying to perceive any creature other than you until the spell ends. The spell ends early if you stop speaking.
