Player: "Ok, McSneaky wants to get inside the estate without raising an alarm. I'll be prowling, trying to enter through the back door"
GM: "Great. It's dark out and there are not too many guards. But it's a big estate so there is always a chance someone comes along. We'll call it risky position, standard effect."
Player: "Ah, I got a 4. Success with a complication".
GM: "You pick the lock and enter, smooth as silk, but it turns out the cook is here, preparing for tomorrow's breakfast. He looks at you in alarm and seems like he may scream. What now?"
