Change the NPC's damage for certain weapons

[ArenaMaster]

I've been playing on master mode, and when I'm fighting a large group of bandits the melee bandits don't really do that much damage like 1/7 of my hp damage. But when it comes to their archers, holy crap, they do like 3/7 of my hp in damage (they kill me in 3 hits). Now what I want to know is, using skyedit or something else, what can I do to change the damage all NPC archers do? What variable should I change?

For archers, either reduce the damage of the bows or the arrows (they are under ammo), or reduce both. Remember to use the batch edit function if you want to change several (highlighted) items to the same value, at the same time.
