This is for people who need good arrows, but can't buy or find them.

First you need an archor enemy, then find out what kind of arrows he/she has.

If said person has arrows you like, find a good high wall to back up agianst then when he/she shoots step to the side and pick the arrow.

This will almost always work - I've never had someone run out of arrows while doing this.

I always got bored after 50 or so though... this is great for glass, ebony and other powerful arrows.
