Dance Fever

You pick out a person to be your star dancer and target it.  The creature must dance and move at half speed.  The target gains the poisoned condition and takes 3d4 psychic damage each round.  The target may move at full speed if it makes a DC 10 acrobatics.  If the target dances within 30 feet of another of the caster's enemies that new enemy must make a Constitution save or contract the dance fever with the same ability to spread to others within 30 feet.  Once one successful save is made the creature is immune to dance fever for 24 hours.  If the dance fever is dispelled or ends on the original target it ends for all other secondary targets.
