Death's Grasping Hand

This dark and chilling spell allows the caster to summon a skeletal hand with spectral tendrils of frost to emerge from the ground under a creature, grappling a inflicting chilling frost damage. The tendrils are not only physically restraining but also sap the warmth and vitality of the target, leaving the momentarily weakened. The target must make STR or DEX save or be grappled and will take 1D10 Necrotic damage and 1D4 of frost damage. Target cannot regain health points until end of your next turn. If target saves, it is not grappled and takes half damage. If grappled, target must make saves at the beginning of their turn. Upon a save, the target is no longer grappled but will take half frost damage.

Spell can be cast at higher levels: Damage increases at level 5 by 1D10 (2d10)  and 1D4 (2d4), level 11 by 3D10 and 3D4, level 17 by  4d10 and 4d4.

*The grappler can choose to release the grapple at any time without needing to use an action. The grappled creature can also try to escape the grapple using an action by making a Strength (Athletics) or Dexterity (Acrobatics)
