The archer AI is mysterious to me; sometimes they're really responsive (like, the thralls around my house will shoot at a mob sneaking up behind me that I didn't even know about), and sometimes they just don't notice anything even if it's right in front of them. Having eight of them seems to drastically increase the odds of at least one of them locking on, though. I think at one point I had three of them shooting at once.
If anyone wants to take a whirl at upgrading their equipment be my guest. Right now I have snake arrows on half and fire arrows on the other half.
