The point of a negative trait is that it's purely for IC, not that it's the downside to a better quirk. If there was to be an advantage it'd be best to have it as a tier 2 trait and/or earned after a certain condition, like Disgraced Knight -> Regained Honour or how Sentimentality (Weapon) works.

Also that 'Nerd' trait concept is just overpowered for anyone playing Hexer.

You are right, it was a concept just for the sake of saying we need a reason to actually invest in such trait. Like others said, people would just avoid it and RP it out. The "Nerd" Trait would be surely overpowered if one does not take into fact that other traits like that could be done and that it could've been done with adjustments, as you said and I expected, it would be too strong the way I designed it.
