ryu,
If I understood you correctly, I need to tell you that when I went back to the monestary for the wheel key, I forgot to go down to the beach where we started and hunt for venom crabs...later on I went there and reloaded just the lower monestary area until there were venom crabs on the beach...it took ten tries...reloading the Trynton Upper Branches area has been absolutely fruitless in my quest for Spider Silk so I gave it up...sometimes it works...sometimes it doesn't.
I don't normally reload unless someone gets killed unnecessarily or, as in the case of my first trip into the cemetery dungeon in this game, when low-level monsters were there and running away from us! A simple reload before I stepped into the teleporter resulted in scorchers and the like...things that would take us on thinking they had a chance...had I not reloaded, I would have been chasing Apuses and Rats LOL...not much fun.
