Hey I ran this in a session for the second time a bit ago and I have a few comments/questions/ points of confusion. I'm about to run it again so I'd like to keep improving it.
Something I only realized after my second running is the "The Adventurers" is not a reference to the goblins, but a reference to the NPC adventuring party that is entering the temple! I think I'd only read the lowercase adventurers as the NPCs for some reason.
I don't understand the pacing, in terms of how many actions should be attempted. The group very quickly entered the tower by breaking and window, looked around each room, but kept going down. They successfully broke or picked the door to get down. By the time they were down with the spider people it was probably only turn 3. They also made it back up by turn 5. Perhaps I wasn't throwing them enough obstacles, but it seemed like they wanted to go up or down steps in a room really shouldn't be an issue or even a roll.
Also a more general question is how should we treat fairly simple actions that have the chance of not working? I ended up mostly saying they risked breaking it, or the item they were using, but that felt very uncreative after a few times. It also because confusing whether they could reattempt things. Particularly in the firey lab, they kept failing to escape, but it felt silly to just kill them for failing to leave a room, but there wasn't any other way out. I ended up saying they had to burn away an item each time, and then the fire died out. I guess I could have injured them, but I think that would have wiped the whole party.
As a twist/ mistake I made the orb a bit more magical and the ooze was a bit afraid of it when they waved it or the replica. They didn't linger long, but I think if they messed with the ooze it would have attacked the item it was once afraid of. In the moment I couldn't describe the runed chamber well, so the orb became the most important device for containing the ooze.
As a funny note, one of the goblins drank the ooze in the runed bottle. I had to talk to a friend not in the game to figure out something for the next session. We decided to cause the stomach ooze to drag the player to the big ooze. That ended up being funny. A leg was lost.
Thanks for your creation by the way! I've been enjoying it and trying to get more people to play.
