Wave of Death

You send negative energy coursing through all creatures within range, causing them searing pain. All targets must make a Wisdom saving throw. They take 4d20+20 necrotic damage on a failed save, or half as much damage on a successful one.

All other creatures killed by this spell rise at the start of your next turn as a zombie version of their species that is permanently under your command, following your verbal orders to the best of their abilities.
