In roleplaying games, the dump stat is the ability attribute you put your characters lowest score into.
It is the the attribute that might be least useful to the kind of character you want to play. In real life, the same term is used as a funny slang for something that you might feel like you're great at. Charisma can be used to describe a character’s force of personality, persuasiveness, personal magnetism, ability to lead, or physical attractiveness. This vintage design is for those that feel that they might be a little lacking in one or more of those departments.
