Binding Domination

This spell is the most dangerous necromancy spell, capable of breaking the mind from splitting one’s will up between all of their necromantic minions permanently, in order to increase their numbers drastically and make their will among them absolute. Choose any number of undead that are under your control for which you have a soul pearl for within range. Your spell binds them to this plane and your servitude for until they die, and makes them leave a corpse behind when they die, regardless of whatever the spell that made them says in its description, and if that corpse is raised again, then the creature's perma-bound status is kept between reanimations. In addition, if you attempt to target more than 5 undead at a time, then you must make an Intelligence saving throw, with the DC being 10 plus 1 for every target you’re attempting to cast this on at a time. On a failed save your mind is torn apart, causing you to take 10d12 psychic damage, have all potential targets of this spell have your control over them lost, and causing you to be frightened by all undead for 1 hour. On a successful save the spell completes as normal on the chosen targets.

On each of your turns, you can use a bonus action to mentally command any creature you bound with this spell if the creature is within 300 feet of you (if you control multiple creatures, you can command any or all of them at the same time, issuing the same command to each one). You decide what action the creature 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 creature only defends itself against hostile creatures. Once given an order, the creature continues to follow it until its task is complete.
