Moder often gets stuck on the ground where she can't hit you, especially if you're lower than she is.

I just fought Moder as well, but she didn't get stuck very often. Using full Fenris armor and a silver knife. It was actually easier than I expected with the knife, but it took longer than using a sword.

I also fought bonemass a few hours ago, with the same equipment, and that, of course, was a cakewalk.

Tomorrow might be Yagluth, since I already found two alters, and I'm playing all light armor/weapons, and I don't think there's much to make in plains. Maybe a new dagger, and some lox pies, but I can't think of much else.

FWIW, full Fenris armor was a huge grind. I don't know if this is just a bad map, or if more of the larger mountains are locked behind the wall of mistland now, but I sailed to the mistland barrier 5 or 6 times before I found enough mountains/caves to max the full set. It is nice armor, but I'm sure I coulld have made multiple sets of wolf and/or padded in the time it took.

I also made the flesh rippers, which are a disappointment. They look good on paper, but they're just not (IMO) as good as a good knife, especially combined with a buckler.
