Thanks for the quick reply. It was the Barnabus' cave puzzle. Just after I posted, I gave it another try, and by some fluke got through the first (sinking) platforms. That made me more hopeful, so I persisted, making LOTS of saves along the way, and finally succeeded. The game rewarded my persistence with a good piece of armour in the chest, and in another area an undead dropped epic level earrings, so I'm happy. I think the problem is simply that I'm in my sixties, which is hardly the target demographic for these games. If they made it so I could do these puzzles with no trouble, younger players would be bored to death!
Oh, I'd met Hermaphroditus - his? voice is hilarious.
