Tech Wizard

Tech Wizard is a Fallout Tactics Trait, available only to Ghouls.

You spent your formative years hunched over a bench learning tech stuff. Trouble is you've ruined your eyes! You get a bonus to Science, Repair and Lockpick skills (+20%), but a penalty of -1 to Perception.

Despite the racial restriction, both Ed and Slim boast this trait. This is probably an oversight.
