I don't think the arrows actually killed anything. I have no idea what their stats were, but it usually required a full attack with power attack for my character to bludgeon one to death and that's in excess of 170 damage.
We were going through something like 6-9 arrows a round with full attack actions for 1-2 rounds ... I forget. Basically, they wouldn't have wanted to sit around smiling, as that was something like 1d8+8+3d6 from my +2 Mighty Composite Longbow, 1-2 times a round, and the fighter has one as well, but they could have retreated. The GM had them try the logical tactic that had worked in the past of hitting us up with Dispels, but the AntiMagic Field rendered that useless, as we didn't actually have any functional magic on us anyway.
AMF would usually be a higher level tactic, but OldDrewID's character gets it as a 6th level domain slot. If my character could, I'd be using it quite often. I'd rather go in without any spells lately, than get hit with TDMs again and again.
