Of all the Dwimmermount supplements this one is a must have. The others are nice, I bought the map book and the illustration book as well, but this is a MUST if you are trying to run Dwimmermount. I got back into the game after a decades long absence. I hadn't been a DM since the Gipper was in the White House. This took all the stress out of running a megadungeon for my OSR group. Maps are keyed, there is a random encouter table, everything you need to run the level is included in two pages. ALL megadungeons should have something like this. Money very well spent in my opinion.

A great tool for running Dwimmermount. For each level you get a high resolution (designed for printing at 11x17, but still readable at 8.5x11) map with much more detail than the maps in the Dwimmermount book. Each room is keyed with its number, all the monsters and NPCs (NPCs that will talk first are even keyed as a different color than straight combat encounters), a room description of 1-5 words is printed directly on the map, and it it even has icons showing you the locations of magic and treasure. You also get a one page summary of each dungeon level showing you the random encounter table, and summaries of major features, factions, and level entry points.

I noticed at least one minor error. An NPC (Melissa in the Halls of Lesser Secrets) is shown on the map but is not in the key.

It's said the product is designed to have the level summary printed on the back of the level map, but I would probably print it spiral bound so that the summary for each level was on the back of the map page of the next dungeon level, so that they are both visible at the same time when the dungeon tracker is open on the table.

I would definitely get this if you bought the Dwimmermount book and you are planning on running the dungeon in person. It's not a must have if you are playing on a virtual tabletop but I'd imagine it would still be useful.

There is nothing in the dungeon tracker that is specific to D&D, LL, ACKS, or any specific ruleset.

I'm currently 7 sessions in to a Dwimmermount campaign. While the dungeon itself is remarkable, I would say the same of Barrowmaze, in which I've also run a campaign. What has set this experience apart is the Dungeon Tracker. I have a copy printed and laminated, and I keep behind my screen the two sheets appropriate to the level that the characters are exploring. Being laminated, I'm able to use wet erase markers to easily make notes and track time while having all of the most necessary details of the level right in front of me.

While I still keep a copy of Dwimmermount open on a small table to my side so that I have access to detailed room descriptions, the Dungeon Tracker seriously reduces the amount of page flipping I have to do during a game. That has translated into a tighter game and a more enjoyable experience for the entire table. The Tracker has also allowed me to keep my notes on the dungeon much better organized. With Barrowmaze, my copy of the book was littered with Post-It Notes, one per room that the PCs had explored, on which I had written what PCs had taken and defeated, what was left behind, and what may have moved in afterwards. Using the Dungeon Tracker with Dwimmermount, I can do a better job of maintaining a living dungeon environment while spending less time doing so.

I don't know how much value the Dungeon Tracker would have in purely electronic format, but printed, laminated, and perhaps bound using coil stock, I've encountered few game aids that come close to providing this much utility. For a referee running a game in Dwimmermount, or for anyone interested in tools for helping games play as easily as possible, I'd give this a very strong recommendation.

what about the monsters and mayhem happening in the dungeon? What the hell are you going to do when you've got those twenty orcs baring down on you and the PC's are with their back to the pit trap or the flame spells? There's a the dungeon tracker for this situation and another thing that makes this series unique in a way. I can hear the grognards howling in anger and frustration at the inclusion of such a thing being included in an OSR campaign. Believe me I'm howling along with you but hear me out. The Dwimmermount Megadungeon Tracker is pretty neat, it allows you to keep the party seemingly off kilter while actually neatly organizing the whole affair nice and concisely all in one go. Here's the product description: The Dwimmermount Megadungeon Tracker is a unique play-aid designed to help you get the most out of a 13 levels of Dwiermount. For each level of the dungeon, the Megadungeon Tracker provides a double-sided reference sheet, with a specialty keyed map on one side and a level summary on the other. The map provides brief descriptions and contents for each room on the level; the level summary covers each level’s history, factions, wandering monsters, access points, and special areas, and allows the dungeon master to easily track turns and marching order. This brings up the motives, reasons, hatreds, rivalries and high OSR monster weirdness of Dwimmermount. There are reasons for everything here and not unlike an Edgar Rice Burroughs novel those reasons bare out over the time as the PC's go deeper and deeper into Dwimmermount. If and only if they get that far. They're going to need a ton of luck, plenty of magic, and a butt load of healing potions. The dungeon tracker is one handy little device to have and its a nice addition to a DM's arsenal. The lessons of the tool box are there to be used and I for one I'm planning on making my own version of the Dungeon tracker. A very handy device to have at the table.
