7th-level Spell: Twisting Eruption

Sorcery/Whispering (Conjuration)

You target a point and call forth tendrils, twisted vines, and gnarled roots of dark energy that erupt from the ground in a 60-foot radius. All creatures of your choice in the area must make a Dexterity saving throw or be restrained as the shadowy plant tendrils grasp and drain the life from it.
At the start of a creature's turn, if it is restrained by the spell, it takes 2d10 bludgeoning damage, and 2d10 necrotic damage. Each time a creature takes necrotic damage from this spell, the caster regains 1d4 hit points.
A creature restrained by the tendrils can use its action to make a Strength or Dexterity check (its choice) against your spell save DC. On a success, it frees itself. A tendril can be destroyed, freeing a creature from its grasp. They have an AC of 10, 20 hit point, and are immune to all damage besides radiant and fire. Spells that deal radiant or fire damage to creatures in an area of effect also affect tendrils in that area.
Creatures that end their turn within the radius while not restrained must make a Dexterity saving throw or become restrained by the tendrils.
