Curse of the Jimmy Legs

"Why can't I just hold still?" The target of this spell will feel deeply restive and uncomfortable,as they jerk about in an effort to alleviate their symptoms. Failing a constitution save, they will be forced to move their full speed in one of three directions (player provides the options, DM chooses which option) at the beginning of each turn. For the duration of the spell, the target has disadvantage on all attacks and spells.
