5. Flags.
Flags are various characteristics that don't affect characters personalities, but affect events and actions.
Magic Gift: an ability to use magic. Characters without this flag cannot use any spells.
Psychic: an ability to read minds, like telepathy for example. There are others, but all they go here.
Nerd: yeah, well, bookish characters and so on.
Combat Training/Adventurer/Assassin: special training flags.
An example: anyone can use weapon, even at 0 skill, but either after special training or with enough experience it becomes natural and effective, especially for self-defence.
Half-Sister: nuff said.
Heavy Drinker/Always Hungry: flags for autobuying system.
Virgin: a temporary flag.
Kleptomaniac: for thiefs.
In case if you wonder where artificial body or alien flags are, they are a part of race system. Like, all angels are aliens, and all androids are artificial.
