Advanced Adventures: Under Shattered Mountain (OSR)

Advanced Adventures: Under Shattered Mountain (OSR)

This adventure clocks in at 13 pages, 1 page front/back cover, 1 page editorial, 1 page SRD, leaving us with 10 pages of content, so let’s take a look!

This review was requested by one of my patreon supporters, to be undertaken at my convenience.

So, as always for the Advanced Adventures-series, this module is intended for OSRIC-rules, but adaption to another OSR rule-set is very much possible. Nominally intended for 5 – 8 characters level 9 – 12, the adventure is very modular and represents more of a sandboxy backdrop than a unified narrative, and it should be noted that, difficulty-level wise, the adventure ranks in the upper echelon. There are a few encounters herein that are very dangerous and that will potentially destroy careless or unlucky players. These are not always telegraphed that well in advance, so an old-school mindset that can deal with character-death is very much recommended. On the definite plus-side, it should be mentioned that the more intelligent adversaries do get tactics that set them apart and help the GM render them appropriately dangerous, making them stand out a bit more than they’d otherwise would.

As far as supplemental materials are concerned, we get 4 new monsters – a pretty deadly toadstool critter, cavern crows that can be driven into a frenzy by the scent of blood, the lightning devil, and a unique devil are provided, all with appropriate stats. As far as adversaries are concerned, some beloved classics can be encountered, and a few of them are surprising – but I’ll get into that below.

The pdf does contain two new magic user spells: At 3rd level, we have Hestler’s Verbal Disruptor, which generates a white noise style acoustic-dead zone, is an interesting one. Black Embrace, a 7th level spell, booby-traps a corpse, which will embrace the living, draining their life-force. Cool visuals there.4 magic items are included as well, with experience and GP values noted properly. One of them, a flask that can be used to poison targets or be harmless, is nice, though here, a deviation from OSRIC’s default assumption of save-or-die for poisons would have imho made sense from a design perspective. A cooldown or countdown of sorts would have certainly made falling prey to that item less frustrating. One of the items is cursed, and honestly, it may actually be fairer than this one.  A bloodsucking dagger (with rather nice mechanics) and a rod are also part of the deal here.

Now, before we go into SPOILER-territory, let’s briefly talk about how this is set apart from most modules: Shattered Mountain is vast, and as such, it contains miles upon miles of tunnels that lead from a) to b) – in a way, it is reminiscent of a wilderness crawls inside a mountain, limited by the claustrophobic tunnels. This structure allows and encourages insertion of your own adventure modules and scenarios and characterizes this firmly as more of a backdrop than a primary narrative. This is also further emphasized by the random encounters table, which is pretty hefty and feels down to earth enough.

In fact, the lion’s share of the adventure is taken up by a variety of not necessarily connected encounters, each of which comes with its own functional little map. These are NOT aligned in a linear manner, which, once more, represents a big plus as far as I’m concerned. On a downside, the respective areas (10 of which are provided) are designated with letters: “Area F”, for example. However, on the respective maps, we have starting positions of dynamic adversaries, for example, also denoted by letters. When you look are the map of “Area B” and read “A, B, C”, you can’t help but feel that this choice of labeling wasn’t too wise. Using Roman or Arabic numbers, glyphs, whatever, would have been more comfortable for the GM in these cases.

Beyond these encounters, there is a more conventional 2-level mini-dungeon included here…

But in order to discuss more of the details of this adventure, I will have to go into SPOILER-territory. From here on out, I strongly urge potential players to skip ahead to the conclusion to avoid SPOLERS.



All right, only GMs around? Great! So, among the encounters, we have, among other things, a slightly loopy fungal druid (including the series’ by now traditional deviations from OSRIC’s formatting conventions), a tribe of troglodytes, aforementioned cavern crows in conjunction and cohabitation with gargoyles, trolls, earth elementals, stone giants – the aesthetics here seem to be deliberately close to what you’d expect from a classic AD&D adventure – whether you consider that to be a bug or a feature depends on your own tastes. For the most part, I have to admit to being not exactly blown away by them, as the terrain simply doesn’t matter as much as it probably should. Compared to the fantastic “Stonesky Delve”, the caverns under shattered mountain feel quite a bit more sterile. I did mention that this module can be really deadly, and perhaps unfairly so. This claim primarily stems from one of the encounters, which springs not one, but two very old red dragons on the PCs – once they pass a certain threshold, they’ll be blasted by not one, but two breath weapons. No, the dragons are not hostile to another; they work together.

While it is “realistic” in a way that going down the wrong tunnel may get you killed, I did not consider this one to be particularly fair or enjoyable. There is no foreshadowing here, and I’d strongly advise GMs to seed some warning signs for the players. Otherwise, this is pretty much one of the bad “Lol, you die”-type of old-school encounters that doesn’t earn its lethality.

More fair, if certainly no less deadly, would be aforementioned mini-dungeon: Sheth, aforementioned unique devil, has his own little complex that spans a total of 21 keyed locations. This mini-dungeon is a hackfest in the purest sense, and if you’re looking for some good ole’ murder hobo-ing, this’ll do, perfectly. From the gorgon guardians to a lamia to twin rooms housing no less than 6 (!!) stone golems in total, this complex is brutal. Said lamia has btw. high-level adventurers and a trolls charmed, making the encounter function somewhat akin to handling rival adventurers. We even find nilbogs here, and as a whole, this dungeon is deadly, but cool – there is for example a really cool trap, where a collective of screaming magic mouths may render the PCs unconscious. While this can TPK a group, mundane means to offset the trap (as well as magical brute-forcing) are viable tactics, making this a cool example of a trap that has more than one step, and one that rewards player skill over PC luck. I really liked that one. Sheth and his cohorts are similarly a challenging and cool final encounter. Here is a lost chance, though – the lightning devils and the pool featured in the final encounter don’t really interact, and as cool as some of the trap/hazard-related aspects of the complex are, they don’t extend to actual interaction with the creatures, which makes them feel a bit more sterile than they’d otherwise seem.


Editing and formatting are good of a formal level, though there are deviations from OSRIC’s formatting conventions. On a rules-language level, I’d consider this to be precise and well-crafted. Layout adheres to the two-column b/w-standard of the series, and the pdf comes fully bookmarked for your convenience. The pdf features no interior artwork beyond the editorial page, and cartography in b/w is functional and solid. However, no player-friendly, unlabeled versions have been provided.

James C. Boney can write really, really cool dungeons. The author gets the theme and tropes of classic fantasy really well, and I am particularly enjoying the tactics of his adversaries, as well as the creative and fair traps that his modules mostly seem to feature. At the same time, I couldn’t help but being somewhat unimpressed by this offering.

I love the notion of Shattered Mountain. The crawling through labyrinthine, lengthy tunnels is something I really love. Heck, I’ve written more than one book devoted to the theme of subterranean gaming. That being said, this feels, whether by design or by lack of inspiration, somewhat cookie-cutter in what the encounters offer. They are pretty segregated from one another, and theme-wise, there is no encounter within that I couldn’t have improvised on my own. On the plus-side, the mini-dungeon makes for a rather enjoyable hackfest – I can see that one work great for a fun convention game, for example. If you’re looking for a hard, but fun hackfest, the mini-dungeon included certainly delivers.

Still, this module has the somewhat unfortunate timing of having been released after “Stonesky Delve”, which not only offers a more alive, terrain-wise interesting adventure with verticality, nooks and crannies to explore, etc. – it also offers much more bang for your buck. This is by no means a bad adventure or hub/backdrop, but it also could have been much more. If “vanilla” AD&D flavor is what you’re looking for, then this delivers – if not, then you’ll be better off with “Stonesky Delve” or similar adventures. As such, my final verdict will clock in at 3 stars.

You can get this adventure toolkit/framing device here on OBS!

Endzeitgeist out.
