You get 5 more points to spend on your stats, but all skills are reduced by 10% in addition to receiving 5 less skill points per level.
J.E. Sawyer's Fallout RPG[]
You gain +7 points to spend on primary attributes, but you earn perks only once every four levels.
Lionheart[]
Because you have more innate abilities than most, you have not spent as much time honing your skills. Your statistics are better than the average person’s, but your skills are lacking. All stats have a +1 modifier. All non-spell skills are lowered 10 points. You receive 4 fewer skill points per level.[1]
Notes[]
The trait provides an extreme starting advantage. The extra seven attribute points far outweigh the relatively minor skill penalties.
