These bosses are also easy to cheese tbh. Bonemass, build a treehouse and stay there with poison potions. Make 200 frost arrows, stay behind a tree that fell down, he'll just stay there.

Not sure that you can argue that the game is fine to play solo if you have to exploit the AI to do so. But if that's how you enjoy playing the game... each to their own.

I play solo and, as others have said, careful preparation has paid off. Any deaths I've suffered have been from recklessness... and I can't fault the game for that.
