I actually did link a lot of the up/down ones in the Sea of Despair...

Quite a few of them aren't linked all that well (go down, go up, and you're somewhere else). It's very fun.

In the Great Illithoid Prison, there's that green-colored room (Descending a broad, precipitous stair). Southeast from there (Springs of bubbling, black fluid), you're missing a few rooms to the in.

EDIT: In lvl 0.

Thanks a lot, that is now added.

I love Undervault, I've just started bashing down here... and the XP is great, especially the kraken!

Edit: moved map here

Thanks to a great response, the 1597th (and final!) room is on the undervault map, I got to sample the delights of a lava pit in the serpent skull, discovered raezon's temple, added a room missing in the black tower in Glomdoring and have added the whole (I hope!!) of Viravain's temple to the map!

Edit again: Emperor's glory, Temple of Isune.

Hmpf, as I thought the area around the wreck has changed, there definately wasn't a single room with no exits there when I first mapped it.

Oh, oh. You need the Spirit World!

So far as I can tell it just consists of two rows and two columns. The rows are X (I think like 10) rooms long and the columns are X-1 'cause if you squint all the way northeast you can see yourself. It's one of those non-euclidean places that loops in on itself too. I don't think you can really map that, heh.

I think I might have seen it on another post once, but can someone give me an idea of the afflictions and damage type down in the tosha pits/spirit plane?

You need to add the Tomb of Isune.

At the Intersection where the northern mountains meet Avechna's peak (the bottom of the path that lead down from the peak to the northern mountains), go NW and then up.

Jeez, you've really mapped the world out well.

Hmmmm, so that's where it went to! I've relabeled the other room (the one where we fought the 2 dimentional things) to just "glowing seal". Thanks.

The Glomdoring map seems a bit out of date.

YOu still have the Master Ravenwood labeled as the "Blasted trunk" and you don't have the Glomdoring guild halls.

Here you go.

I don't have any others apart from the Shadowdancer's I'm afraid. Glomdoring has been a bit of a problem, until recently, due to Caffrey being a Serenwilder. I haven't been able to just wander around like I usualy do looking for new things. I had to have an armed escort to map the Arena! However, any guild that would like it's guildhall mapped is more than welcome to contact me. I would preffer to be allowed in to have a look around myself, but if you really don't want to on account of me being a Seren, then please send me an accurate map and I will include it in the update.

Quick question: how are you not a planeswalker yet?

Heh, good question. Mostly because I was very unlucky... I wasn't as quick off the mark as Kaervas, and only got a few of the guildhalls in during open beta (I'm assuming here that he did - I haven't asked him), and then there was the whole thing with the explorer ranking system breaking, so when I realised it would be a good idea to get any guildhall still open... it didn't count anyway.
If you think about say an avarage of 15 rooms per guildhall... well your looking at over 200 rooms easily, I have only a fraction of that.

However I reckon I might get Planeswalker if I could get catacombs and tosha. Catacombs is about 130+ rooms and tosha pits are.. 20? Those two should bring me pretty close to Planeswalker. I would like to get it, but I enjoy the mapping anyway so I'm not too bothered.

Tried Tosha today... the damage wasn't a problem at all, I was tanking a hunter, a shark and a spider at once... but I can't cure afflictions to, well, literally save my life.

I thought the catacombs were broken or something? There sure wasn't anything near 100 rooms last I checked.
Speaking of catacombs, on Spectre Isle, in the palace (I think), there is an IN room you are missing.

Thanks for that, I had the room connected to the library (which I recently removed), but that explains where the mystery square came from!

I'm not sure about Catacombs being broken, I haven't tried to go down there for quite a while. However, some people who have explored the whole thing gave me that size.

I'm pretty sure it's about 100 rooms or so. You have to open up the various passages and tediously bash the gar-stuff in the way. There're three levels if I recall correctly (the second one is a doozy).

Running around in the undervault when it first opened was so confusing. Thanks, though. Now I see how much of it I wasn't even aware of.

Now if only I didn't have to run from every single fisher.

Interesting. I can never work out how to get to the third level. Only levels I can get to is the one with the gatekeepers (from rift on Spectre Isle) and the one with the levers (from Shallach)

edit: moved

My only consolation is I have one more room than you there.
