If you're bored as all hell (as I often find myself) there's a couple fun things you can do with your archer type characters;
Go out in the open, and shoot an arrow directly up. Try to catch it on it's way down. (By catch, I mean 'take' it, but while it's still in mid-air.)
An easier way, or for practice, you can shoot at a high wall, when it bounces off, catch it.
A more useful thing to do would be train Marksman, but this one is a little complicated, and you need Adoring Fan for it.
Things you will need: Hundreds of arrows, a bow, dozens of paintbrushes, Adoring Fan, wilderness.
What you must do:
1. Take all the items listed, as well as Adoring Fan, and go out into the wilderness. Maybe even a cave, somewhere a guard will
never stop by. A place no one will ever stop by. If it's a cave, clear it of bandits or whatever.
2. Make Adoring Fan 'wait' in the middle of a large opening.
3. 'Drop' paintbrushes all around him in a circle. Unless you have the Unofficial Patch, they'll float. Make sure he's completely surrounded.
4. Turn up the difficulty slider all the way, and begin shooting him, he can't escape, as he's trapped in a bunch of floating paint brushes.
5. Heal him when his health gets too low.
You can do this for as long as you want, and become a Master of Marksman in a couple of hours.
