Some time ago I got a pdf copy of Dyson’s Delves. I didn’t have to pay for it — it was a consolation prize to replace something else he’d tried to send to me and which was apparently lost or stolen in the mail — and he didn’t ask for a review, but it’s only fair to post one now because I have had some time to look it over and have even used one of the scenarios. <Edit: There is also a Dyson’s Delves II? I didn’t know about that until just now when I went looking for links. So this review is just about the first one.>
Anyway idea behind Dyson’s Delves is to provide both a set of usable dungeon adventures and a set of maps, ready to be keyed and stocked (with sheets of blanks provided on facing pages for those who want to keep a permanent record in their copy). Some of the maps and adventures have already been published on Dyson’s blog. They are all pretty good. There is a “mini-mega-dungeon” that was originally published on the blog as “Dyson’s Delve,” and which consists of eleven smallish levels (with room for expansion). This mini-mega-dungeon has multiple entrances, so higher level adventurers could bypass the goblins-infested uppers, and there are multiple paths through the dungeon — the party may need to go “up one, down two” to find everything. This dungeon could easily serve as the centerpiece to a dungeoneering campaign, and yes there is dragon in there somewhere. The dungeon is designed to take a party from first to sixth level. (I have a copy of the “deluxe edition” printed out that I keep on hand just in case I ever need to run something with no preparation… though I’d probably swap out the goblins for almost anything else.)
There are several other keyed dungeons, ranging from single-level adventures to multiple-level dungeons. The dungeons have a variety of difficulties, which is very nice for DMs looking for a quick side-adventure in a campaign, as I am often am because I did not have time to prepare or because the players go so far afield of what I expected. There is a surfeit of first-level one-page-dungeons, so it’s nice to find delves here for mid-level parties. My favorite is probably The charmed grotto (for level 5-8 characters), which I ran in my home campaign and provided a decent challenge to a mid-level party, but you’ll also find adventures for 3rd-6th level parties, ranging from the award-winning one-page The worm’s gullet to another multi-level crawl, Erdea Manor.
The blank maps are generally very good. Anyone who has visited Dyson’s blog will have seen his work, so there is not much for me to add about that.
It’s available in PDF, softcover, and hardback. No-one asked me, but if he did I’d tell him to see about offering in a spiral bound edition, as my experience with perfect-bound print-on-demand has been that they do not hold up well to use at table, especially if you’re writing in them. As it is I guess you could get the pdf and print yourself a copy and have it spiral bound at an office supply store. Or just three-hole punch your printout.
In any case Dyson’s Delves is great idea, well-executed and worth a look.
