Exactly as the title suggests. How do you get the contracts? Do you have to get caught by the shopkeeper or whatever.

Also the more rare DB Contract. How do you go about that bad boy.

I'm out to piss off everyone in the game and have thugs and assassins jumping from behind every bush in Skyrim at me...LOL

The Dark Brotherhood Assassins coming after you just happen randomly.

Thugs can be contracted to come after you if you kill someone or steal from them, but those are both one time events if I remember right.

Tell a wizard you hate adventures, wait for 13 dwarves to knock at your door, feed them, get contract.

This is pretty accurate.

I always got the Assassin's coming after me.
