Find the witch

You help the Amazons in taking the castle while making your way to the witch.
If you can take her out this will all be over and the fight will be won.
Sneaking through the halls of the castle you take out many soldiers who are on guard.

As you sneak through the hall you suddenly notice a woman with a green hood up ahead.
She has red hair and a sly smile on her face.
Her green leather clothing tightly hugs her slender frame. She has a quiver full of arrows on strapped to her back and a bow in her hand.
In a swift motion she pulls an arrow from her quiver and nocks it on her bow.

Before you can say something she shoots the arrow towards you.
