Recently over at the Greyhawk Grognard, there was a discussion of how to deal with “the 15-minute workday.” This is a situation in which PCs become so risk averse that they immediately retreat to a safe haven after expending any resources at all in the dungeon, nickel-and-diming their way through the even the shallowest dungeon levels.
In the comments, Talysman responded:
*Discourage* the players from returning to town every time they run a little low on resources? I’m trying to *encourage* them to do that! It doesn’t have to be easy, and things can certainly change between visits, but I think there should be a series of short expeditions instead of “hanging on until the last hp”.
I agree with Talysman that this behavior is precisely the kind of careful management the lethality of an old-school dungeon requires, but I’m sympathetic to Joseph’s concerns that the necessary risk of a dungeon expedition can be eroded if the PCs are risk-averse in the extreme. The solution I would suggest is to make the dungeon itself a resource to be managed: If the PCs appear to be hauling loot up risk-free, others will be emboldened to try their luck in the dungeon’s depths.
The linked document details what it is essentially a random encounter roll when treasure is brought up from the dungeon; the likelihood of encounter is modified by the secrecy of the dungeon’s location, the party’s health on returning, and the amount of treasure retrieved. The latter is variable by market class (ACKS’s I-VI reckoning of market size, with I being global metropolises and VI being tiny hamlets), and based on the monthly wage of three heavy infantry and the number of said infantry on the market. The translation of other ACKS-isms to B/X-like games should be fairly transparent.
Since returning to town from the dungeon is typically a call for a short break in the games I’m in, it should also afford me the opportunity to roll some dice and replace a defeated group of orcs with a NPC party eager to get in while the getting is good.
