Animus Blast

You unleash a blast of necromantic cold that freezes the very life force of creatures caught within it. Each creature in a 60-foot cone must make a Constitution saving throw, taking 5d8 cold damage and 5d8 necrotic damage on a failed save, or half as much damage on a successful one.

If a creature is killed by this spell, its flesh freezes and shatters off its body, and its bones are animated as a skeleton under your control. Skeletons created by this spell serve you as if created by the animate dead spell, except that they become inert bones after 1 hour and cannot be maintained. Skeletons created by this spell have vulnerability to fire damage.
