Good Natured

Good Natured is a Fallout, Fallout 2, Fallout Tactics and Lionheart Trait.

You studied less-combative skills as you were growing up. Your combat skills start at a lower level, but other skills are substantially improved.

Fallout 1, Fallout 2, Fallout Tactics
First Aid, Doctor, Speech and Barter get a +15% bonus. You get a -10% modifier to starting combat skills (Small Guns, Big Guns, Energy Weapons, Unarmed, Melee Weapons, and Throwing). This is a one-time bonus only.

This trait is useful, as it is unlikely for even a combat-oriented character to use more than 3 of these skills, and in all likelihood only 2. As such, 20% is "lost" while at least 45% (Speech, Barter and Doctor) is gained. In fallout 2, first aid is mostly useless as one can Wait indefinitely. This is not the case in fallout 1, and so in fallout 1 all 60% of this is useful.

Lionheart
Your combat skills start at a lower level, but Barter and healing rates are substantially improved. Barter gets a 25 point bonus. You also get a negative 5 point modifier to starting melee combat skills (One-Handed, Two-handed and Unarmed). This trait cannot be selected with Nasty Disposition.
