Skilled

Skilled is a Trait which appears in Fallout, Fallout 2, Fallout Tactics, Van Buren, Lionheart, J.E. Sawyer's Fallout RPG, and Fallout: New Vegas add-on Old World Blues.

Fallout
Since you spent more time improving your skills than a normal person, you gain more skill points. The tradeoff is that you do not gain as many extra abilities. You will gain a perk every 4 levels but start with an additional 10% in all skills.

Fallout: New Vegas/Old World Blues
This trait was not in the base game, but was added with the add-on Old World Blues.

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.
