Hey,

I'm looking at running a one-shot for some of my friends recently (one of whom has never played D&D or any tabletop RPG before). I figured a dungeon crawl is probably the best way to introduce people to the game, so I'm after some fun, low-level dungeons to pilfer. Looking at starting them around 3rd level but anything for 5th and below would be good. Worst comes to worst, I'll try and design one myself but I'm not the most experienced at building dungeons, so any tips in that area would be greatly appreciated as well.

Hi HumesHefner, welcome to the forums o/

I cannot offer much-much help, I am afraid, but maybe having a look at the One Page Dungeon Contest entries can give you some good ideas.
There you can find all kinds of dungeons that whose map and description fits just one page, and with a wide thematic  range as well.

Hope it can be of help to find something suitable :)

Thanks heaps LeK, that looks like it'll be super useful :)
