I have a 47-135 shadow bow and a 55-153 normal bow for the shadow resistant enemies. Even with normal arrows these bows can carve through most enemies long before they get within range of my heros axe. When you reach act 3 and realise that you will never be able to use your money anyway, drop the "convert arrows and sell them doctrine" and instead just use them. then you will have a one shot-one kill weapon even agains the nasty things you will meet later in the game.
