Chaos Spark

Shoot out a combination of lightning and necrotic beams dealing 2d8 lightning damage and 2d8 necrotic damage. Make a ranged spell attack against the target. On a hit, the target must make a constitution saving throw with a DC of 10 + your charisma modifier. On a fail, the creature will be paralyzed. On a success, the creature will not be paralyzed and the damage is halved. During the start of each of the creature's turn, the creature must make a constitution saving throw with the same DC. On a success, the creature will no longer be paralyzed.

At higher levels: When you cast this spell using a spell slot of 3rd level or higher, add an additional 1d8 damage (for both damage) for every level above 2nd.
