Taleweaver's Discordant Melody

You cause a burst of cacophonous and clashing chords from random instruments to happen at a point you choose within range. Each creature in a 20-foot-radius sphere centered on that point must make a Intelligence saving throw. A target takes 5d6 psychic damage on a failed save, or half as much damage on a successful one. Also on a failed save, a creature has Disadvantage on all attack roll made on it's next turn.

The fire spreads around corners. It ignites flammable objects in the area that aren't being worn or carried.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d6 for each slot level above 3rd.
