Why do I call most of my reviews Mini Reviews? Because I don't break the product down to its components and pieces like some others. I'd rather give you my impressions and feelings then inadvertently drop spoilers. Besides, I don't don't have the time or energy to write a magazine length review. Wish I did 'tho, and god bless those that can and do.
Anyhow, on to the Mini Review of Stonesky Delve, an Advanced Adventure for 6-10 characters of levels 4-7. The module assumes the group will have access to the AD&D core rulebooks and / or OSRIC, but I see little reason why it couldn't work with Labyrinth Lord, especially with the Advanced Edition Companion. with what little conversion is needed done on the fly.
The module itself was run as a 2 part tournament module at the 2010 GenCon Convention and as such it comes with pregen characters, or, as I like to call them - new NPCs for my collection.
This is one of those adventures that the DM should know very well before running. The caves in the module are more then the standard D&D 2 dimensional fare (yes, it is advised to let the players know to prepare for spelunking).
If run for the standard gaming group as part of a campaign, it would probably last one long session or two shorter sessions in my estimation. If run for a gameday or convention, it should take two 3 1/2 to 4 hr slots to finish. Included is a tournament scoring system.
Its a nice change from the standard dungeon crawl as it forces the players to think in three dimensions. It should be fun to run and play in, but the DM must have a good handle on the adventure before running it. Yes, I am repeating this piece of advice. It bears repeating ;)
