Entropic Ray

You create two rays of raw chaotic energy and hurl them at targets within range. You can hurl them at one target or several.

Make a ranged spell attack for each ray. On a hit, the target takes 2d8 damage + your CHA modifier. The type of the damage is determined by the result of the d8, as indicated below. 

1- Acid, 2- Cold, 3- Fire, 4- Lightning, 5- Force, 6- Poison, 7- Psychic, 8- Thunder

If you get doubles, another ray bursts out from the target, and shoots toward a new target within 60 ft. 

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, you create one additional ray for each slot level above 2nd.
