Turn Vampire

Once per Long Rest you get to turn a living or dead being into a vampire. If the Target is dead or willing to be turned the spell is an automatic success. If the target is unwilling to be turned they need to make a constitution save (CON DC 14). On a failed CON Save the target is turned into a vampire and will serve the caster until dismissed. If the target succeeds the CON Save it has advantage on the next attack role against the caster.

On each of your turns, you can use a bonus action to verbally command the vampiric familiar you made with this spell if the creature is within 60 feet of you (You can only control one familiar at a time). You decide what action the familiar will take and where it will move during its next turn, or you can issue a general command, such as to guard a particular chamber or corridor. If you issue no commands, the familiar only defends itself against hostile creatures. Once given an order, the familiar continues to follow it until its task is complete.

The creature is under your control for 24 hours, after which it stops obeying any command you've given it. To maintain control of the creature for another 24 hours, you must cast this spell on the creature again before the current 24-hour period ends. If the spell ends or the familiar is dismissed, the target will travel to your home castle to join your army's ranks.

At Higher Levels. When you cast this spell using a spell slot of 7th level or higher, the con save increases by 1 for each 2 level above 5th.
