First of all, big big thank you for playing the adventure and for your feedback! I'm always happy to hear playreports! I mean I create these little things to be played! :)
I don't know if you noticed but the troll and the goblins are taken straight from the corebook of Cairn.
This adventure, the cave part at least, was originally part of the German translation of the game as an introductory adventure. I extended it with a small town und the woods for the jam.
During playtesting, I had some character deaths occure as well and a stealthy approach proved to be generally more successful indeed.
That said it's the first time somebody got the help of Blil during the fight and that really is exciting to hear!
I hope you and your players had fun nonetheless! ;)
