can someone point me towards said dungeons, im guessing its cave... no clue where its located.
if you follow the path east from town and then eventually upwards it leads to flooded cave dungeon. There is another in the mountains but you need to find 3 key fragments and combine them to enter that I think. No idea which one the item to talk to Acacia is though, but I think there is another dungeon nearer to her lair?
If you're looking at your map. Locations tend to get a cloud over the tile they are in. Caves to the east is straight forward. There's a Glacial Fortress in the High Mountains you need a key to get in and I believe way in the bottom right there is something to find in the swamp. The swamp is kicking my teeth in, so I have yet to risk it.. Flooded Cave gave me half a key for Glacial, I assume the Swamp is hiding the other half. Also, I think Orson's house (Way North West) Gets a cloud sometimes.. I dunno, the map is rough, I need to take a close look at it.
Blah, it's night on my save. Either way, you might be able to see hints of stuff by looking closely at it. I only really know about the cave, the fortress and I've been murdered in the Deep Woods to the north.
Map markers? I don't see that working out.
The maps are largely generative and the area's contents change every day. Whatever you marked won't be there when it changes the next day, defeating the purpose. If you mean to mark dungeon locations, the map kind of already does that for you. The cloudy areas are where dungeons are, and their entrances never change, though the surrounding area might. So I'm not sure how useful this idea would be in practice. Unless, I'm missing something.
Maybe dev could make visiting dungeons remove the clouds on the map and tell you the name of the dungeon when players hover the mouse over it? No point keeping it hidden once you've seen the place.
