Going to run some undead for a boss fight, and while I was looking through some potential bosses I found the Obzedat Ghost. They seemed pretty interesting, in particular this ability:
Convene the Ghost Council. The ghost summons the other four members of the Obzedat. At the start of the ghost's next turn, the other members appear in unoccupied spaces within 30 feet of the summoner. The ghosts each roll initiative when they appear.
Seems like a pretty good way to have a single boss turn into a squad of 5, but it got me thinking: if it summons other Obzedat Ghost, do those ghosts also have this ability, and in turn could summon another four, and so on and so forth?
I know from the story there's only 5 of the original counsel, but this boss isn't going to be in Ravnica so I'm wondering if RAW, it's technically possible for the ghosts to summon more ghosts and just overwhelm with sheer numbers.
