Item Drop Rates?

I remember a few months back when I used to be more active on the game (starting back up slowly nowadays again), I had seen a forum post in this forum somewhere about how to find out drop rates of certain items from certain quests and even gave examples, but I can't find it anymore.
I was wondering if anyone could either explain the method of doing this to me (if it's still even possible) or if someone could get the drop rates of some Nulgath items for me, I'll follow up with a reply if that's the case.

If you're using Grimoire: Grimoire > Loaders/grabbers > Quest items and drop rates

You need to load the quests first.

How about the item drop rates that the monsters drop?

Just check the wiki for that info.
You could also try lurking in the battleon forums.
