Thievery

Effect: 

You have the Thief background at its full possible bonus of +5, without having to spend your normal background points on it.

Adventurer Feat: 

Regardless of your level, you gain the bonus power thief's strike in addition to your normal number of powers.

Champion Feat: 

Once per day, you can deal full damage with thief's strike instead of half damage.

Epic Feat: 

Twice per level, you can steal something with a successful thief's strike that you would not be able to steal ordinarily, but that would require a bit of magic, e.g. a dream, a spell, someone's hope, a memory. The theft won't be permanent. Every day, roll a hard save to determine whether you can keep what you stole for that day. Also, you can never steal the same thing twice.
