Woosh! You Have Smol Peener

You point your finger to a target you can see within range. If the target is a male, their penis is shrunk to 1 inch long and their balls miniscule for 10 minutes. During this time, the target always has disadvantage on Charisma (Performance) checks as their voice is constantly cracking, becomes comically high-pitched, or anything else to the DM's approval. If the target isn't a male, the target takes 1 Psychic damage.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, you can target one additional creature for each slot level above 1st.
