Mud's Constitution Save

As a bonus action, John can cast heat metal on his enemy. He also has to do a constitution saving throw or else he drops it. And at the else mode, I roar at that guy as loud as I can. Make an intimidation check just give me a one. Give me a one! It's going to be very bad for us both. What does the roar sound like? Only a 10. You almost blew out your mic there if I had stopped and you'd have seen me just opening my mouth and nothing would have come out.
