This is how I utilize weapon ranges:
The three ranges represent short/medium/and long range respectively. At short ranges, apply +1 bonus to damage; at long ranges, apply -1 to damage.
YMMV, do what feels right at your table.
Cool thanks. That's what I'd guessed the idea was, but (unless I'm missing something very obvious!) the rules don't specify. I know I can make it work however I want/need, I just wanted to make sure I wasn't overlooking something in the text.
