Constriction

The crushing grasp and merciless gaze displays an ambition that cannot be quenched with gold, but can be sated with blood.
Your body becomes eerily serpentine and you strike forward, attempting to grasp a creature within range. Make a melee spell attack. If you hit, your grapple your target and squeeze them, inflicting 5d10 bludgeoning damage. Until the spell ends, the grappled target is also restrained. As a bonus action on each of your subsequent turns while you have restrained the creature, you can continue to crush the target. The creature must make a Strength saving throw. If they fail, they take an additional 5d10 bludgeoning damage. If the target escapes the grapple, the spell ends.

At Higher Levels: When you cast this spell using a spell slot of 6th level or higher, each instance of bludgeoning damage increases by 1d10 per spell slot level above 5th.
