Addled Mind

As an action, you can speak aloud a word or short phrase in void speech. One creature of your choice within 10 feet that can hear you must succeed on a Wisdom saving throw against the caster's spell save DC or be frightened of the caster for 1 minute. A frightened creature can repeat the saving throw at the end of its turn, ending the effect on itself on a success.

Other creatures who can hear you suffer minor reactions to the void speech such as spontaneous nosebleeds, headaches, bits of hair falling out, and other unsettling effects. The first time you use this spell, you suffer no adverse effect. If you use it again before completing a short or long rest, you take 1d4 necrotic damage. Each additional time you use it before finishing a rest the necrotic damage increases by 1d4.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the DC check increases by 1 for each slot level above 1st.
