I know the frustration, Charis. Those doors can be a pain.
One approach is to write down the possible combinations, and then try them out. Reload when you run out of Serpin coins until you get the key to all five doors.
A second approach is to use the list in Best Tips, as Bsftcs suggested. I'd do that, if I didn't already have 'em written down from my own experiences.
As was mentioned, you missed just one step in the process: putting an empty flask underneath the egg press to capture the spider nectar.
BTW, spider nectar also works as a cure poison potion. You may want to make a couple of extra ones, if you've got the flasks...
And if you haven't done so yet, get your cleric or ranger up to level 4 Vine and learn the Cure Poison spell. It's more than a wee bit important...
Good luck getting going... and when you're ready to ask about the remaining area you're having problems with, fire away [img]smile.gif[/img]
