Tomb of the Serpent Kings: My Adaptation Notes for OSE - Part 1

 Tomb of the Serpent Kings by Skerples, with art by Scrap Princess, is an awesome dungeon adventure which you should immediately grab if you haven't already.

It's a very good dungeon per se, and is also famous for being a "learning" module both for players and GMs who want to familiarize with the OSR style of play.

It is available as a free pdf, but I've grabbed the A4 Print-on-Demand version and I'm very happy with it. I'm preparing to run it for a group of total newbies, and see how good it is at its intended job!

And since I'm going to use Old-School Essentials, I've prepared a few adaptation notes, so why not share them?

Here's also my very quick map (made with the awesome Worldographer) to have a bit of a backdrop "world" to just start playing.

The tomb is the dolmen icon just southeast of the starting town of Fortana, and the Brandonia town in the woods northwest is a renaming for Brandonsford, which I hope to play next!



So, here are the notes for the False Tomb and Upper Tomb sections.

The lower tomb will be covered in the next post! is available here!

Room 18: Stairs trap. 1d8 damage, save vs death halves.

Room 19: Stone Cobra Guardian. This is supposed to be very strong, so I had originally decided to give 1d8+3 melee damage, but after some feedback on Reddit I've decided 2d6 is more in line with similar instances in BX.
