A normal person has something in them that stops them from taking the lives of others, wheather it is morals, instincts or fear. You do not. The only value that other's lives have for you is what they can give you, and you're ready to take it by force. It's not even that you take pleasure from killing - it's just as normal for you as cutting down trees is for a lumberjack.

Murderer:

• Starting equipment: A dagger painted black, clothes that are easy to get blood washed off, a one shot tiny crossbow, a disarming smile and 10 victims buried where no one but you will find them.
• Starting Skill: (roll d4) 1. Butcher 2. Farmhand 3. Criminal 4. Soldier
• Gain +1 to stealth for each level in this class
• A: Drop of the hat, Perfect target
• B: "Innocent"
• C: Getaway
• D: Clean, +1 attack

Drop of the hat: Most of the people you meet have to convince themselves before they use killing force - not you. You gain a free attack and a step at the beginning of each fight that represents your ability to kill others without a second thought. This attack is considered as if it is a surprise attack.

Perfect target: Most people do not always have their guard up. You know how to exploit that. Whenever you attack a creature that is unable to defend themselves (this includes surprised targets) if your attack hits it is automatically considered a critical hit.

"Innocent": You've never felt guilt, but now you know how to show nothing that suggests that it was you did it. It is impossible to detect any crime that you committed from your behaviour, unless magical means are used.

Getaway: You don't want to be caught red-handed - this is why you've learned to flee by instinct after doing your deed. After attacking, you can move for 30 ft for free (once in turn).

Clean: It's one thing to kill someone in a way that they don't even realize what has happened. It's another to do it so that nobody knows - if you spend 30 minutes cleaning a crime site, no one investigating it can get any clues as to who did it.
