More megadungeon mechanisms

Happy New Year!

After yesterday's post on the last lantern-bearer (the one who always gets away), I've been thinking of a few more mechanisms for the episodic megadungeon campaign I plan to run this year. These are mostly fairly arbitrary-seeming rules that will - I hope - add tension, excitement and a bit of grit to the game.

I'll probably use some variant of the original D&D rules for this (possibly Whitehack). I want to strip things right back, so that hit points are low and deadliness is high. In our regular D&D campaign, I use STR in the Into the Odd style: with characters losing STR points after their hit points are gone and having to make a STR save each time they take STR losses. That works really well - but for this campaign, I might go for maximum deadliness, so that starting PCs may well just have 1 or 2 hit points each. That should amp up the risks nicely.

So here are some of these mechanisms.

1. Adventuring parties are always accompanied by an equal number of non-combatant porters/lantern-bearers and the same number of pack animals. There's no point going on a treasure-seeking expedition to the Underworld if you don't have the means of carrying off the loot. And - in meta-game terms - that gives us the pool of reserve PCs, the encumbrance and lighting solution, and the continuity mechanism that I outlined yesterday. The pack animals also carry plenty of food, water and fuel.

2. Party casualties are always replaced from the lantern-bearer pool, with a new character rolled up on the spot. Such replacements can be of any class (hitherto hidden talents) and are equipped from what can be salvaged from the dead or provided by the rest of the party. The pack animals are likely to carry a few spare spears and bow. I'll probably have hand-to-hand weapons do damage by class rather than type (fighters d8 or d10 for two-handed; clerics, elves, dwarves and thieves d6 or d8; magic-users d4 or d6), to avoid any class restrictions on weapons.

3. Expeditions always end when the session ends. This isn't an original idea, of course, but I think it'll provide a nice rhythm and aid continuity, especially as the players aren't likely to be exactly the same each time. I might provide some narrative cover for this ("You need to get out by nightfall - the place is crawling with monsters after dark"), or I might just leave it entirely arbitrary.

4. Escaping lantern-bearers don't bring party treasures or equipment with them. They are assumed to have fled as fast as their legs can carry them. But they do know where the loot was last seen - and are able to guide a new party back to that point. It's unlikely, of course, that the loot will still be lying around. But if Baldros the Bold and his men met their end at the hands of the Iron Hand hobgoblins, it's a fair bet that the hobgoblins now have the golden idol that Baldros stole from the troglodyte tribe.

5. Gold provides XP - but only when it's spent (on training, better equipment, magical research, etc.) Living costs are included in this it's assumed that the PCs pay for their upkeep during the course of their training or studies. I'll probably seriously revise whatever armour and weapon list I use so that better weapons (two-handed swords, etc.) and - especially - better armour is seriously expensive. That way, there should be a nice dilemma for expedition survivors: better gear or character advancement? And of course, this mechanism keeps the focus squarely on loot - which incentivises dungeon-crawling.

6. All parties have a nominal leader - the PC with the highest CHA. This is largely for "historical" atmosphere in the dungeon: "That's where they got Captain Juras and his lot. That's him there - turned to stone!" or "See the tarred head on the spike up there? That's Chardro. 'Prince of Thieves,' he called himself. But the orcs are no respecters of royalty". The leader also has total control of the lantern-bearers/porters and pack animals, however. They go where he tells them to (except when they flee, of course), which should help to keep the party together - especially in light of the following.

7. There is safety in numbers. In the dungeon, large groups are much safer than small ones. You might think that a couple of thieves could sneak off on their own, relying on stealth and guile to get in and out with choice items of loot. But the dungeon ecology is against you. Wandering monsters - dangerous vermin of all sorts, including kobolds (or equivalent) - are always ready to pick off the isolated. And these creatures can see in the dark and are ever watchful from the safety of their burrows. Stragglers or break-off groups incite regular wandering-monster checks - and those monsters are numerous and emboldened. This makes plenty of sense: small creatures like kobolds are unlikely to risk frontal attacks on large, well-equipped groups (the kobolds don't know that the lantern-bearers won't fight). But ambushing a couple of thieves in the darkness? It's a near certainty. 

The point of all of this is to create a game in which the dungeon, rather than the party, is the focus, and in which 'victories' over the dungeon are to be prized. A total-party kill should come as an exhilarating last stand - and a successful expedition should feel like a real achievement. So too should taking a character up to second or third level - gaining the chance of surviving a hit or two in combat.

I'll be running this with 1/72 miniatures, which offers more space for all those pack animals and lantern-bearers on the table - and especially over Zoom. That scale is also somewhat "depersonalised", with the miniatures being more generic and interchangeable - which I see as a good thing for RPGs. 

The key, though, will be creating a megadungeon with plenty of interesting features and perils beside its inhabitants. I started work on this last year, and I hope to make it a major focus in 2021.
