Defenseless

You are considered defenseless when you are completely unaware and oblivious about an incoming attack (or several of them), for example, if your someone manages to approach you stealthily from behind. You are also considered defenseless when you are somehow unable to react, for example, if you are Stunned, Knockout, or asleep.
In this state, you are a viable target for a Sneak Attack.
The GM determines when a character is Defenseless.
For example, if someone managed to successfully sneak next to you while you are sleeping, or behind you while you are alone, cooking in a campfire, you should be considered Defenseless.
