Valhelsia Structures generates a variety of abandoned structures, ruins and dungeons in your world. It gives you something more to explore in the game and look forward to finding. Plus you may come across some rare loot! Some of the structures are fully formed homes that look recently abandoned or even still lived in with fires still blazing. Perfect for setting up camp or starter city.
And dungeons below have gotten a massive overhaul with this mod. There are typically more spawners so they can be much more treacherous. They’ve been completely overrun by moss and spiderwebs but the loot can be more than worth the risk.
