As the troll begins to whirl, its dagger-like claws rending the flesh off of the surrounding wolves, you try to get up and out of the way of the viscious attack but are too slow to react. The shock of the sheer ferocity of the rending claws is more than you have ever faced before, and before you know it the troll has ripped your blade from your hand and rends your body mid-flight. With a screeching snarl, it pitches you to the water below, where you hit the bottom with a thud. The water rushes into your open mouth, and you taste the scum and disease-laden water nearly entering your lungs, but at the last microsecond you catch your breath and stumble backward.

Ooooor not. This is gonna end fantastically.
