One of the tough aspects of roleplaying a genius is that the character's "smartness" is only as flexible as the player's own understanding of what being smart means. I've run into this with a player whose character has the Math Wiz trait… they get a hefty bonus of 30 to any action that involves on-the-fly calculations, but what does that mean? What kinds of situations would involve on-the-fly calculation, and how do I keep the trait from being under or over powered? My first thought were that Freefalling and Gunnery involved plenty of complex instinctual geometry and physics to determine trajectory, although having a +30 bonus apply to every use of the skill seems to not be the intended purpose. Any opinion, forum?
