I'm on my 2nd stoneskin potion, so i'm guessing its been 45 minutes of me pulling those cat people out around 3 small buildings in the desert. I've checked each building and I've scanned using the select object button and I can't find the entrance. (The wiki says one of the ingredients for 20% sword boost potion is in there)

Also...Ive tried the Gazluk City castle a few times...I've slowly pulled and killed and have ran around the inside of the castle...can't find that entrance either.

Thanks for any help!
