Evoke Death

You stretch out your hand, forcing one creature within range to make a a Constitution Saving Throw. On a failed save, the target takes 3d4 necrotic damage, and has their hit point maximum reduced by half the damage taken. If this reduces their hit point maximum to 0, they die. A creature slain in this way rises the next day as a Lesser Undead, who sees you as it's leader. It retains the size and movement speeds it had in life, but all it's other abilities and traits are determined by the Lesser Undead Stat Block. The target's hit point maximum can be restored if they take a long rest. On a successful save, the target takes 1d4 necrotic damage, and their hit point maximum isn't affected.
