I'm creating a necromancer wizard player character and searching for the most optimal amount of undead to control. I searched for the lore of the monsters, and found that Ghasts tend to be leaders in packs of ghouls. But I couldn't find how a Ghast does that, or how many can it can maintain in order.
So that makes me wonder. Can a controlled ghast be the boss of an uncontrolled pack of ghouls? And if he can, how many could it command?
That could significantly boost the amount of undead my necromancer could control by indirect means:
The idea I have is to create ghouls using my 6th level spell slot, and maintain the superior slots for a ghast, who will introduce the newcomers to the pack, so when the next day comes, they already are in a group controlled be the more powerful undead, who will in turn be controlled by me.
