Intelligence/Fallout

Intelligence is one of the seven primary statistics in the SPECIAL system.

Gameplay
Modifies: the number of new skill points per level, numerous dialogue options, and many skills.

Low levels of Intelligence impacts gameplay. In some cases, where a character with normal vocabulary would need to persuade them or offer a service in exchange, these characters will often give the character gifts or allow them entrance in certain areas for free out of pity.
