Widow's Web

Striking both palms down upon the ground, a web of necrotic energy emits from the casters hands and multiple black, web like strings rapidly snake along the ground toward up to five enemies the caster can see within a range of 60 feet, leaping towards their target and engulfing them in cold, cocoon like, necrotic void. Each target must make a Dexterity saving throw, taking 8d6 necrotic damage on a failed save, or half as much damage on a successful one.

Alternatively, you can target a single target and spin a web dedicated just for them, dealing 12d6 necrotic damage on a failed save, or half as much damage on a successful one.

The dark energy and webs can travel over obstacles up to 5 feet high, and extinguishes any flammable objects or light sources along its path that aren't being worn or carried.

This is a play off Liam O'Brien's, Widogast's Web of Fire, but altered to fit my PC!!
