The World of Dreams

I have been doing a lot of AG quests recently and found that hyloth pops up quite a bit. The problem with the hyloth quests are that the bottom of hyloth only has like 10 creatures spawn when it spawns and it only seems like 1/2 of those monsters drop the item. Is there a way to possibly increase the spawn in there a tiny bit? I also find that the bottom level of a dungeon should be a little more difficult that that.
