Red Speech

Known also as Wizard-Tongue, the Red Speech was a self-defense technique passed on through wizard dynasties. However, pratictioners are few and far between in this day and age. When a wizard finds themselves in trouble they can recite the chants of the Red Speech to cause those who hear it great discomfort. Possibly providing a distraction or deterring would be attackers.

As an action, you begin to recite the chants of the Red Speech causing creatures around to suffer from terrible headaches. Creatures within a 30ft radius of you that can hear the Red Speech must make a Constitution saving throw against your spell save DC. On a fail, the creatures have disadvantage on Intelligence and Wisdom skill checks, and their speed is reduced by 10ft.  This effect lasts 4 rounds if used in combat, but 1 minute if not. 

Once used, you must complete a short rest before being able to use it again.
