Chaos Arc

An arc of silver and purple energy leaps from the tip of your finger to one creature or object within range. Make a ranged spell attack against the target. On a hit, the target takes 2d4 damage. Choose one of the d4s. The number rolled on that die determines the attacks damage type, as shown below.

1. Cold
2. Fire
3. Lightning
4. Thunder

If you rolled the same number on two d4s, the chaotic energy leaps from the target to a different creature or object of your choice within 15 feet of it. Make a new attack roll against the new target, and make a new damage roll. The second arc cannot leap again. The second arc must target a different creature or object. 

Objects not being worn or carried are affected in the following ways:

A flammable object hit by fire ignites.

A non-magical flame that fits in a 1 foot cube is extinguished by cold.

A metal object that fits in a 1 foot cube is made red hot by lightning, larger metal objects are warmed slightly.

An object weighing 5 pounds or less is pushed 5 feet away from the origin of the arc by thunder.

This spell's damage increases by 1d4 when you reach 5th level (3d4), 11th level (4d4), and 17th level (5d4).
