Ah, Charisma. The classic "dump stat".

For those who don't know this term, Dungeons & Dragons characters are described by six numerical statistics: Strength, Dexterity, Constitution, Intelligence, Wisdom, and Charisma. During character creation, players often get some leeway in assigning scores to these stats, in order to generate a character who will be suited to their desired adventuring and loot-collecting profession.

• Strength controls how well you hit and how much damage you do in combat. Important.
• Dexterity controls how well you fire ranged weapons and how good you are at avoiding being hit in combat. Important.
• Constitution controls how much damage you can take and how well you resist poison. Important.
• Intelligence controls how well you can cast spells and how easily you learn skills. Important.
• Wisdom controls how well you resist bad magic and how keen your senses are. Important.
• Charisma controls how good you look and how well you can play music.... Yeah.

So guess which stat gets the lowest score? Anyone who doesn't put a low score into Charisma must be treated with suspicion. They might be into evil stuff like "interesting character concepts" and "struggling against adversity" and "roleplaying".
