Roastmaster

You can use this feat once a per long rest. Having trained hard, you gain the ability to roast your opponents so badly that it physically causes them to take 1d8 psychic damage plus your Charisma modifier. This damage cannot be blocked, reduced, or redirected except by a spell of 7th level or higher. Whenever you roast your opponent in this manner, roll a d20. On a 20, your opponents closest friends, admirers, or worshippers laugh at how badly your opponent was roasted, causing extreme embarrassment for your opponent and causing your own fame to grow significantly.
