Archery
From UO: Origins - Wiki
Gaining Archery Overnight
To GM archery you will need around 3k - 5k arrows, most easily acquired by buying out the arrow stocks of Provisioners or Bowyers.
You will also need a safe house to run this in where you can block off a tile with wooden boxes.
Once you have blocked off an area in the safe house, cast Blade Spirits (or have someone else cast this) in the blocked off area, and equip your bow.
The blade spirit should begin attacking you automatically causing you to fire back, however if there are other people around, you may need to include a "Target Closest Red" and "Attack Last Target" in your macro.
