Agree! I'm kind of stuck as I don't want to build anymore and I'm just not good enough to kill Moder... sailing disconsolately around and waiting for fish to jump into my longship
Moder is not that hard to beat to be honest, you just need a shit ton of arrows, and a good enough bow like the Draugr Fang. Then it's just spam on her until she goes down.
Though Yagluth is even more laughable. The frost hammer destroys him.
