Bore

You begin to drone in a monotonous tone about a dull topic, causing everyone within range that can hear you to fall into a trance-like boredom. Each creature of your choice that can hear you must make a Charisma saving throw to avoid this affect.

On a failed save, the target has disadvantage Intelligence checks for the next 8 hours. They also take 1d6 psychic damage. The spell ends if you can no longer speak.

The damage goes up by 1d6 for every level this is cast above 1st.
