Unendurable Frenzy

Causes the yellow flame of frenzy to violently burst forth from your eyes. All creatures in a 15-foot cone in front of you must succeed on a dexterity saving throw or take 5d8 fire damage and must make a Wisdom saving throw. On a failed save a creature has -2 on saving throws against madness for the next minute, or until it succumbs to madness. If the creature fails the saving throw by 5 or more it succumbs to madness. On subsequent turns you can use your action to keep the flames of frenzy going. The spell ends if you use your action to do anything else. While the spell is active your speed is halved.
