This is one of the adventure ideas I had based around using a very specific creature, and a creature that doesn’t feature that often.
In Gemsting Cave, characters explore a cave once haunted by Gemstings – Giant Scorpions – which have now returned after many years.
The cave can be dangerous, as the Gemstings are able to climb on the walls and roof, attacking from three dimensions.
Gemsting Cave is meant to be a stand-alone combat encounter but has plenty of role play potential. I also liked the idea of attacking the players from all three dimensions!
Combine this adventure with one of many free cave system map makers you can find online and you have a full drop in location to use in your campaign. The Gemsting stats you can take straight out of Creature Law.
