Envious Pursuers

From within you, 5 shadowy manifestations of envy rise
above your body. These manifestations remain until a hostile
creature moves within 60 feet of you. The manifestations then
begin pursuing the creature, moving 30 feet toward it at the end
of each of your turns. When they reach the hostile creature, it
makes a Constitution save or takes 10d10 necrotic damage, half
on a successful save. A creature receiving more than 50 damage
from this spell is stunned until the end of its next turn, unable to
accomplish anything but feel tremendous shame.
