Encounter - The Agath Ring (Patreon)

Face a demonic entity in an ancient ring of standing stones!

This is a simple traveling encounter for a party at around Levels 9 or 10. It should work in any fantasy setting, but I think it's particularly suited to a dark, Gothic campaign, especially one in which demons and devils play a role. 

As always, you can find the full encounter walkthrough and all necessary battle maps attached to this post.

Enjoy!
