I'm GMing Pathfinder 1e this weekend and my players will be delving through a cave that was once a silver dragon's lair. I want to have a bunch of encounters planned out so that I can stretch this crawl out to the end of session, since we have a guest player who we don't want in the story for too long or too short.
Stuff they will find so far:
-Group of Frost Giants in the entrance. They don't speak common, but are pretty chill guys if a player remembers to cast Tongues.
-SO MANY SPIDERS, while escaping down a spiraling cavern. I'll have them crawling out of the walls and stuff.
-A Black Pudding. Never used one of these, and I don't think my players would know what to do immediately.
-Long underwater cave with some aberrations in it, maybe gibbering mouthers. Also a gigas clam with a huge pearl to lure in the party ninja.
-Big ending surprise - it's not a silver dragon's lair, it's a black dragon's lair, and this whole plot was him luring you to get eaten. Why is this cave so long? Because the black dragon just uses his underwater secret entrance/exit for his schemes.
Party is level 10 and there will be 5 of them, 6 with animal companion. Does anybody know any good encounters for a group like this? Doesn't need to be system specific - I'd love ideas for cool cave traps and stuff.
that's how you really get em. They've succeeded the perception/dexterity/seduction rolls to deal with the Mario 64 eel, come out into a larger, safe-seeming underwater space, and then bam! Mario Sunshine eel
Time to brush your teeeeeeeth
