The functions of distance: some reflections on Tomb of Annihilation

I've now read the latest WotC campaign-in-a-book, Tomb of Annihilation. The premise is that PCs have to slog through a massive jungle to get to a lost city (a reimagined version of the 1981 Dwellers in the Forbidden City), beneath which is a massive dungeon (a reimagined version of the 1975/1978 Tomb of Horrors). If you want a full review of it from an OSR perspective, Gus L has a very thorough one here.

Like Gus, I thought that TOA was one of WotC's better offerings. I've written before about how trap dungeons strain my credulity - if the traps represent a serious attempt to kill intruders, why do almost all of them have built-in escape systems which are accessible from within the traps themselves? Are we supposed to believe that Acererak cares about playing fair? - but if you want a dungeon full of traps, there's plenty here to borrow ideas from. The ruined city isn't as good as the 1981 original, being marred by a silly CRPG-style collect-all-the-magic-keys quest, but the yuan-ti temple is pretty well-done. My favourite bit of the book is actually the jungle section, which features a bunch of good locations and random encounters: I liked the sheltered princess being raised in isolation by bird-men, the delusional medusa living in her ruined garden, and the floating rock inhabited by an elf who claims to be a normal wizard but is actually a lich with cupboards crammed full of animated corpses, while the undead tyrannosaurus which vomits up zombie warriors in battle looks like it would make for an especially memorable encounter. But the jungle? That jungle is just too fucking big.

I know I've written a lot on this blog about the potential advantages of long distances. I am totally on board with the idea of making a party of PCs slog for weeks or months through the jungle in order to reach the Forbidden City. What I can't see the point of is having hundreds of miles of monster-infested jungle between the main adventure sites. Putting two hundred miles between the starting city and the bird-men is fine: but the bird-men live fifty miles from the medusa, who lives seventy miles from the floating rock, which is almost two hundred miles from the ruined city itself, all in an environment where the standard movement speed is ten miles per day, and where you'll have an average of two random encounter every three days. I haven't counted the exact number of ten-mile hexes in area covered by the adventure, but it can't be less than two thousand, across which are scattered thirty-odd adventure locations.What's the point of that? Quite apart from the sheer drudgery of playing through an interminable jungle trek every time the PCs leave one location for another, it makes it much harder to get the inhabitants of these various areas involved in one another's lives: instead, each of them functions almost like an isolated little world. (Compare and contrast Curse of Strahd, where the whole campaign takes place in an area that would fit into just two hexes in Tomb of Annihilation, meaning that everyone is constantly up in one another's faces and events from one area can easily cascade into another.)

If you're going to do a hexcrawl, especially one which covers a huge area and involves long journeys from place to place, I really think that the percentage of hexes with stuff in them needs to be quite high - that, or you need a random encounter generator robust enough to fill all those blank spaces on your map with genuinely memorable encounters. The locations in TOA are good, and the random encounters are pretty good as well, but there's just not enough of either of them to prevent the journey through this two-thousand-hex map from dissolving into either tedium or abstraction. (And once you reach the stage where the GM just starts saying 'OK, after twenty days in the jungle you reach the ruined city', why are you even running a hexcrawl?) I find it very hard to believe the module was actually run as written by the playtesters. No group would tolerate forty random encounters with wandering monsters on their way to the actual adventure.

Tomb of Annihilation campaign map. Imagine trekking through all that with a 66% chance of a random encounter every single hex.

If I was going to run TOA, I think I'd split it into three: the 'home base' city on the coast, a month-long but largely-abstracted journey through hundreds of miles of jungle, and then a single 'adventure zone' for hexcrawling, with all those thirty-odd adventure sites packed into a grid of, say, forty-nine ten-mile hexes. That's still a huge amount of territory - over three thousand square miles of jungle! - but it means that every time the PCs explore a new hex, they have a better than 50% chance of finding something interesting in it, and that it's much easier to get all those interesting things to interact with one another. Rally the bird-men against the goblins. Get the lich to adopt the princess. Trick the medusa into making a surprise visit to the yuan-ti temple. It's much easier to make all those things happen when all those groups are living quite close together, rather than being separated by an entire Amazon Basin's worth of impenetrable jungle. The large distances still matter, because safety and resupply are a month's travel away and the PCs have to plan accordingly, but they no longer get in the way of entertaining play.

Otherwise, even encounters with zombie-vomiting undead dinosaurs are going to get boring pretty fast...

  1. Anything more sprawling than X1 just seems to fall victim to abstraction. I'm interested to see if Yoon-Suin and it's approach can handle distances.

    1. Yoon-Suin kinda dodges the issue, because there's no distinction between 'key locations' and 'everywhere else': everywhere is equally adventure-worthy. So there's no inherent need to abstract long distances, because whatever is nearby should be just as interesting as whatever is further away...

  2. I just started running it but only after I beefed up the random encounters, particularly to not make them so combat focused. I really like 5e as a system but it really does not do hex crawls well if they are all combat focused, because most of your resources reset on 8 hours. One way to handle it would be to use the optional rules of 7 days = long rest, 1 day = short rest, which would make the resources management from combat reasonable to challenging players.

    1. It would, but it'd still be a slog to hack through that many random encounters, regardless of whether they were challenging or not. As mentioned above, I'd suggest either reducing the encounter frequency, the travel distances, or both - otherwise the actual adventure locations are just going to be islands in an endless sea of random zombie encounters!

  3. I just started running this last week as well, and I completely agree that the map is a howling emptiness of random encounters. But, as I don't care much for the purported goal of the adventure ("find the Tomb in Omu"), I'm just going to run it as a vast jungle hex crawl, dropping in other dungeons (like Tamoachan, Tomb of the Lizard King, Against the Reptile God, etc.), and adding my own locations. Because I am intrigued by the various locations in the book, and excited to try my hand at hexcrawling without having to come up with the entire map myself.
