Highlight of Sunday’s session: the PCs spent a good half hour+ inspecting what turned out to be a troll’s toilet. The dwarf used talk to stone to ask the cave about it: “the leader comes in and leaves vile abominations in there.” Massive locked door with “BOSS ONLY” on it. Druid turned into a mouse and snuck under and managed, after some doing to unlock it for the rest of the party. They climbed up and ended up using Spirit Talker to talk to the stone slab that was covering the hole, “HELP! SAVE ME FROM THIS HELL!”
Also managed to make goblins challenging for level 6ish PCs with lots of traps, makeshift barriers, flaming things, etc. The fights with goblins turned out to be way more interesting than the troll fight, which was kind of anti-climatic due to the fact that we needed to wrap things up quickly.
