Spoiler !!

Hi, in Act 3 I got stuck in this Encrypted manuscript quest. This is my second playthrough so I have created the sword before. The first playthrough I already got all the items,

On the second however, I seems to lack harpy egg/ Rotfiend tongue. I see there are rotfiends in the sewer and Harpies in the town /mountain I killed loads of them but couldn't get the item drop at all. Is it still possible to get the last ingredients?

Or does anyone kindly have a save file Roche's route and act 3 with the ingredient /sword ready before the final showdown?
