OK, I made it through reim by punching everything fortunately. But it really stunk to not have my main weapon be able to work. I tried shooting probably 100+ times, both a stack of mesile bolts with my crossbow and the stack of faewood arrows with my longbow. None of the shots would land, they all had the "has no effect message."

Obviously, since the bless changes everything should have effect whether its blessed or not. But I did try voln blessing everything, the ammo, the longbow, the crossbow, etc.

I do eblade my bolts/arrows. I stripped the eblade off with 417, and then blessed. But again, everything should hit undead now regardless.

Thats a good hypothesis. If so what do I do to resolve? Eblade my arrows to hit undead???

Lol, I bet that's the problem. Because I have also had the bodkin bolts not work on treekin, which require magical weapons, after the eblade runs out. I didn't get that either, since they are faewood, but I just ebladed them and kept going.

The tip material always used to be the determinant. I haven't used archery for ages, but using vultite tips to make arrows magical was common when I did.
