Skilled (Fallout: New Vegas)

Skilled is a trait

Effects
You gain +5 to all skills, but you gain 10% less Experience Points.

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 but the negative effect doesn't, remaining at -10% XP. 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%.
 * In addition, if Skilled is removed via the Sink Auto-Doc, the skill bonuses remain while the de-buff is removed (this does not affect XP already missed, it merely means that the -10% penalty no longer applies).
 * In addition, if Skilled is removed while leaving Goodsprings for the first time, then selecting the Rebuild Character option, and creating a character that is the exact same as your current one with the exception of the removal the Skilled trait, you will retain the +5 to all skills and lose the -10% XP reduction.
 * If a skill magazine effect is in play, it counts as the base value. For example, if someone didn't have the Comprehension perk and they had an 85 base Science skill, 85+10+5=100 and it would stay that way.
