Trait system

A system with only flaws, traits, general attributes (intelligence, charisma etc) and levels.

The main feature is the traits, photographic reflex's, memory, etc.

You can have world specific ones, for Harry Potter you could have something like 'the mind' with gives +10 levels in occlumency and legilemency(probably spelt them wrong haha) and complete knowledge in both.

Lesser versions like 'closed mind' +5 in oclumency and moderate knowledge in it.

Another example; 'illegitimate child of the force' if anikan is the official child then you are a powerful accident, 30,000 midiclorians count but -5 to darkside resistance roles.

Makes you strong but comes with a downside, get creative and have fun, this can be used in many world since there are no stat points on level up only through hard work and traits.

You could use it in dragon ball a very high powered world or SpongeBob, Star Trek or the flint stones even supernatural or Buffy the vampire slayer( Xander wakes up with the system a year before Buffy comes with visions of 'his' future, only what he in the show was there to witness personally)

Have fun with it.
