question about bows in diablo 1

[Nystul]

Also the massive swiftness is very difficult to find.

In a sense. Most characters are too high level to shop for it and don't item hunt in areas where it would drop. If one shops persistently at the appropriate level, a decent swiftness bow should be very easy to obtain. Trying to get one that is massive AND long war bow AND swiftness will be extremely difficult like any ideal item with 3 requirements. That is a really frustrating thing to try to force (still not nearly as bad as trying to get such an item from Wirt!). A nice bow of heavens can be bought by a high level character in the course of normal play or found in the hell levels in the course of normal play.
