Death Coil

A blast of unholy energy in the shape of a ghostly skeletal Titanoboa streaks to the target wrapping around them and releasing necrotic energy with its fangs. 

Make a ranged spell attack against a target within range. On a hit, the target takes 3d8 necrotic damage.

On a critical hit, the Titanoboa will continue to constrict the target for 1 round. The target of the spell gains the restrained until the beginning of your next turn.
