Cleon
Legend
This is a weirdish monster. I think that I'd rather keep the actual HD of the master fixed and use negative levels to enhance it per minion (or else use positive levels per minion missing as a penalty).
Yes, I thought that would be easier than recalculating the HD each time they lose a minion. Since the original monster was always summoned with a full complement of minions, it seems to make more sense starting them off at max HD and then having them gain positive levels as they lose minions.
Hmm, come to think of it does mean that an Advanced Bloody Bones has additional minions? We can worry about that when we get to it.
Also, if the masters are 8 ft tall and Large, wouldn't that make them pretty heavy?
Hey! You know the Master tries to watch his figure, but those souls of the damned are very fattening to a fleshless skeleton...
We could always make him taller. Say, 9 feet like an Osyluth.
Or maybe he's a minimum of 8 feet tall, and grows taller the more minions he has.
