"Charisma is a combination of appearance, personality, and so forth. Its primary function is to determine how many hirelings of unusual nature a character can attract. This is not to say that he cannot hire men-at-arms and employ mercenaries, but the charisma function will affect loyalty of even these men. Players will, in all probability, seek to hire Fighting-Men, Magic-Users, and/or Clerics in order to strengthen their roles in the campaign. A player-character can employ only as many as indicated by his charisma score"If the primary function of charisma is to determine the number and loyalty of hirelings, and charisma itself was important enough to make it one of the six attributes, then hirelings must be an important part of the game, right? On the other hand, M&M later speaks of
"acquiring a regular entourage of various character types, monsters, and an army of some form."That makes me question whether hirelings were in fact a vestigial hold-over from Chainmail, and little-used in actual D&D play. I'd love to hear anecdotal evidence one way or the other. Did you use hirelings in your games back in the day? Do you use them now?
