Swoop down, that last arrow way to close for comfort

Since the last arrow wasn't too far away from your heart, you decide to swoop down to the clearing. You descend fast, your wings folded around you. A few meters above the ground you throw them out, nearly stopping your fall. You run into the thick foliage and hide behind a tree. After dressing, you crouch and move silently through the foliage. You search your knowledge of magic. Is there anything that could be of use right now?

After a short moment, you remember a spell that makes shadows dance around you, making you incredibly hard to see in the faint moonlight. Another spell comes up, this one allows you to track something almost anywhere, if you can mark it. If you can touch the archer or throw something at him you could switch the roles. You would be the hunter and the archer your prey.

You pick up a small stone and pull out one of your knives and continue searching.

A twig snaps to your right, you turn to look. Its the archer! What do you do?
