An unstable dart manifests on your hand holding pure chaos inside and you throw it at one creature within range. The dart explodes on contact with a creature. Make a ranged spell attack. On a hit, the target takes 1d6 + 1d4 damage. The number rolled on that d6 determines the attack’s damage type, as shown below. If you don't throw the dart it disappears at the end of your turn..

At Higher Levels. This spell's damage increases by 1d6 when you reach 5th level (2d6 + 1d4), 11th level (3d6 + 1d4), and 17th level (4d6 + 1d4). Choose one of the d6s to decide what type of damage the spell does.
