Carrion Cage

Calling on necromantic energies of death and decay around you, you summon a constricting storm of bone around your enemy.  Make a ranged spell attack against the target. On a hit, the target takes 1d8 Necrotic Damage. On a successful hit, the target must make a Save against your Spell Saving DC, the Save type matches the type used to calculate your Spell DC, on a failure the Target is Restrained until the start of it's next turn.

This spell’s damage increases by 1d8 when you reach 5th level (2d8), 11th level (3d8), and 17th level (4d8).
