I knew about dungeons, but I didn't watch any deep dive or anything about it. I wanted to try my hand at it with little information. Here's my experiences, which hopefully will be helpful. Harry and I knew where these things usually start. They're craftable, so therefore, we want recipes. We set out for Ardoris. We checked out the crafting merchant, and moved onto the carpentry merchant. Seemed logical, but nothing there either. I tried Owl's Head, since sometimes it differs by town. Nope. Housing and decoration merhants? Nope. I decided to check out POT merchant towns for recipes. I shopped till I dropped, and found nothing (I think I just got unlucky here). I decided to try the COTO merchants... and found nothing dungeon related. I broke down and asked The Universe for a hint. The Book Merchant, I'm told. I would not have guessed. Books? Are dungeons made out of books? I found such a merchant and bought one of each, whereupon Harry and I recalled back to the house. First things first, I needed an entrance. I appeared to have a recipe for that. Though, I didn't have the gems (and apparently 50 consecutive player vendors didn't either). I ended up buying the coffin entrance from someone else. I plunked it onto the ground, and tried to open it. It wanted some kind of "deed" for the dungeon. I didn't have one. I looked through my recipes for some kind of start room, and didn't find anything. They weren't labeled as "deeds". I must have missed something. I made the rounds through the book merchant, COTO merchants, housing deeds merchant, etc. Nothing labeled "deed" or like it might be one. I looked at the SOTA store, wondering if it was a store-only thing that had to be purchased. Yes, there's several dungeon related thingies there... including a couple "foyers". The hell is a foyer? It looks like a room, with the crafting icon looking like the others... is that what I needed? I had a recipe for that, and its granite requirements were steep. Sounds like promising. Sure, enough, the entrance accepted that as a selectable option. For dumb people like me, maybe the title of the "foyer" should include something about "dungeon start room"? So then I was inside my first, one-room dungeon. I had another room to attach, but there's no instruction as to how to do this. I stumbled across it accidentally. I was at the connecting-hall join, and randomly clicking, a panel appeared which gave me some options. I closed it. I glanced over at Harry and asked, "How did I do that?" I didn't actually know. The wall seemed to have a small hitbox where my cursor lit to green. Looking closer, I saw it. It was an extremely faint blue symbol floating in the air. Apparently that's what I clicked. It'd help if it glowed, or wasn't in the dark. I selected my 1x1 room, and I was well on my way!
