Bugs

 * If you use this at the beginning of the game, you will have the normal effects. However, if you re-apply it before going into the wasteland, the positive effect doubles and the negative effect doesn't double, remaining at -10% Experience. The trait can also be later reapplied at The Sink for a total of 15 points to all skills, while the penalty remains at -10%. (Confirmed on PS3 version 1.07.) In addition, if Skilled is removed via the Sink autodoc, the skill bonuses stay while the debuff is removed (this does not effect XP already missed, it merely means that the -10% penalty no longer applies).

J.E. Sawyer's Fallout RPG
You gain an additional Tag skill. However, you gain -1 skill points every level because you often spread yourself too thin.
