Ohh … I’ll be avoiding the plains for a while now.

My bonemass is about half a days sailing from the plains area where I died. I was looking for a spot to make a base when I was attacked by the serpent and as I was hugging the shoreline I thought I’d step onto land … my mistake.
I can just see a slight outline of swamp to the north of me … and there’s a little island (meadows) nearby to use as a staging post.
I enjoy the exploring part and don’t use an internet map of my seed.

If I can ask another quick question? ….
If I continue to explore swamp tombs … will I find other bonemass locations that could be nearer to my home location?
The one listed on my map is quite a distance away and although it’s fun to explore the map for all I know there might be another bonemass very near to me in unexplored land.

And thank you for those tips, GunForBucks.

Yes, there are random spots for all Boss spawn points. I've found a few Elder spots very close to each other. Best of luck in your adventures
