Hi! Thanks for your kind words.
About damage in combat:
It doesn't matter who's attacking and who's defending; if the hunter rolls under the difficulty score takes damage, should they roll above they inflict damage. The initiative is important in order to be the first deciding what to do. Once you engage in combat, anyone could get hurt.
Ranged combat is a bit different, cause your victim is not usually close enough to counterattack, so you won't take damage. In this case, losing ammunition seems bad enough to me if you fail the roll.
Rolling a 9 in combat:
When you roll a 9 in combat you still succeed with dire consequences. The GM decides what happens in these situations. If I were the one ruling, and 9 is above the difficulty score, the hunter would inflict damage as usual, and lose their weapon, trip (rolling with disadvantage in the next turn), get blinded by their victim's blood... If the 9 is under the difficulty score, the hunter wouldn't inflict numerical damage, but make their victim fall, retreat... and suffer a dire consequence.
I hope this helps you! Have fun playing the game and let me know if you have more questions.
It helps me a lot to know where should I be more clear in the future.
Cheers!
