Longbow

You need at  least two hands to use a bow, regardless of its size. A longbow is too unwieldy  to use while you are mounted. If you have a penalty for low Strength, apply  it to damage rolls when you use a longbow. If you have a bonus for high Strength,  you can apply it to damage rolls when you use a composite longbow (see below) but not a regular longbow.
