Thaddeus's Mind Freak

Any humanoid within 30ft radius of the targeted creature of this spell must succeed on an Intelligence saving throw or be overwhelmed by a need to clap in applause for me, dropping whatever is in their hands to do so. This enthusiastic applause takes up the entirety of their turn. They may repeat the saving throw at the end of their turn.
The spell ends for an affected creature if it takes any damage.
At Higher Levels.

For every spell slot expended beyond 4th level, the radius effect of the spell increases by 10 feet.
