Good question!
There are no Morale stats for monsters in C&C, however, on pages 80-81 of the
Castle Keeper's Guide, one may find rules to adjudicate this sort of thing.
Castle Keeper's Guide wrote:Morale-reaction
Monster creatures are the only creatures which need to roll morale.
Morale does not affect deities and magic items. Monsters, however, can
suffer from poor morale or good morale, whether they are antagonists or
protagonists. Creatures serving as henchmen or hirelings and working with
the characters can become demoralized and quit the characters’ service or even be encouraged to remain longer or under more difficult circumstances.
Creatures who are fighting the characters can suffer the same.
Make morale checks for creatures serving as henchman or hirelings
more frequently than for other NPCs. Creatures possess a host of
cultural, linguistic, religious, and racial attributes they do not share
with players of any stripe. Thus, situations tend to affect them more
dramatically. Roll morale during every combat, during any dangerous
situation or one posing a threat to the creature’s well being, and at the
beginning and end of adventures.
To check a creature’s morale, the character must make a successful charisma save to keep the creature from fleeing; adjust the check by the challenge level of the situation, as determined by the Castle Keeper, as well as the loyalty rating, the character’s level, and any attribute bonus.
What follows this text is a table of recommended modifiers to this roll. Hope this helps!
