bone bramble

Calling upon the forces of nature and foul magics you infuse the targets body and soul with necromantic thorns that rip at the target when they push them selves physically,upon casting the target you see within range must make a con saving throw or be afflicted by the brambles causing them to take 2d8 necrotic damage when ever they take any action or attack after there first each turn or move more than there max movement. Targets that have a body but no soul or vise versa have advantage on the saving throw as the thorns don't take as easily to a vessel without both. This spell ends early if the target dies the caster falls unconscious or loses concentration.

Up casting:casting this spell each level after second will add a additional 2d8 to damage.
