Creeping Shadow

You conjure a mysterious magical darkness from the caster's shadow, enveloping a 15-ft. sphere centered on them. While within this darkened space, the caster can see through the obscurity, gaining a tactical advantage by remaining undetected and perceiving hidden details.

Creatures that start their turn inside of the darkness need to make a Strength Saving throw or be magically grappled by the darkness, on a fail the target is grappled and takes 4d6 psychic damage.
